SECTION 1

INTRODUCTION

1.1 PURPOSE AND SCOPE.

This Technical Order (TO) is to be used with TO 33K-1-100-2, TMDE Calibration Notes, Calibration Interval, Technical Order and Work Unit Code Reference Guide, as a guide for determining calibration responsibility, Work Unit Code assignment, Calibration TO, and calibration interval for Test, Measurement, and Diagnostic Equipment (TMDE) and other Support Equipment (SE). It applies to all work centers possessing TMDE. Items are listed by model number, type number, part number, drawing number and Military Specification (MIL-SPEC) number in alphanumeric order. CAGE codes are listed as info only (manufacturer name takes precedence over the CAGE code when they are in conflict). All Calibration Interval listings are in months. See Section 7 for details on TO 33K-1- 100-2 distributions through the Air Force Calibration Authority Viewer (AFCAV).

NOTE

The AFLCMC/WNM AFMETCAL Division, Air Force Metrology and Calibration (AFMETCAL) program is referred to as AFMETCAL throughout the document.

1.2 GENERAL.

Calibration responsibility and applicable TOs for TMDE are listed in TO 33K-1-100-2 and weapon system Calibration Measurement Summaries (CMS). See Section 4 of this TO for applicable CMS.

1.2.1 If a new item of TMDE cannot be supported using the guidelines of this TO and TO 00-20-14, the calibration responsibility, applicable TO reference, and Work Unit Code (WUC) will be obtained by the Precision Measurement Equipment Laboratory (PMEL) Chief by submitting an AFTO Form 45 in accordance with (IAW) TO 00-20-14, except as indicated in Section 3 of this TO.

Questions about specific TO 33K-1-100-2 listings may be directed to the appropriate TCM or to the appropriate email address: AFMETCAL.K100.ELEC@us.af.mil or AFMETCAL.K100.Mech@us.af.mil. General questions regarding TO 33K-1-100-1 may be directed to K100@us.af.mil.

1.2.2 Calibration responsibility or TO requests submitted by all activities, including DOD and contractor agencies, will include as an attachment technical data, manufacturers handbooks or any commercial data indicating specifications, accuracies, ranges, and parameters of the equipment. Calibration determination and/or preparation of a calibration procedure will not be accomplished unless data is furnished with the request. All data furnished should be plainly marked with the return address. After action is completed, the data will be returned to the originator.

1.2.3 Requests for determining calibration responsibility and/or the applicable TO will not be submitted for:

1.2.3.1 Equipment part numbers having options (or is the base model) that are subsets of a part number already listed.

For example, a determination request would not be submitted on part number 123OPT001 if part number 123OPT001- 002 is already listed.

1.2.3.2 Options such as the following where parameters are the same as the original equipment and a 33K-series TO exists.

a. Rack mount options (R at the end of a part number, OPT-908, etc.)

b. Warranty options (OPT-W30, OPT-W55, etc.)

1-2

c. Service Manuals

d. Front Handle Kits (OPT-907 etc.)

e. Rear Panel Connectors unless the option changes the equipment specifications

f. Connector Type options unless the option changes the equipment specifications

g. Cable length or No Cable Options unless the option changes the equipment specifications

h. IEEE Bus connector

i. Calibration Data (OPT-890, etc.)

j. Shipping Instruction Options

k. Options that provide extra Probes

1.2.3.3 Equipment part numbers already covered by a SERIES entry in the TO 33K-1-100-2.

a. Base part number followed by or proceeded by SERIES is a conscious effort to consolidate like items and reduce the number of entries in the TO 33K-1-100-2. SERIES entries will be used to identify equipment part numbers containing characters used by the manufacturer to designate or identify features of the product when those features do not affect the calibration uncertainty of the original equipment. If the manufacturer’s literature for the item in question uses Options to specify additional features, the SERIES entry is not applicable to the item.

An item listed by an individual part number in TO 33K-1-100-2 will take precedence over a SERIES listing.

b. The features to be included in a SERIES entry are similar to the excluded options listed in Para 1.2.3.2 above (i.e. rack mount, warranty, size, case style, etc.).

c. Entries will appear in the TO 33K-1-100-2 as the base part number followed by or proceeded by the word

SERIES (for example E SERIES, 100 SERIES, SERIES 110, SERIES PG25C, etc.).

d. When receiving an item for the first time, the following should be accomplished to determine if a SERIES entry may be used or if a Calibration Determination Request (AFTO Form 45) shall be submitted:

(1) Look up the part number as identified on the unit in the applicable CMS or TO 33K-1-100-2. If a listing for the item is found, STOP - no Calibration Determination Request (AFTO Form 45) is required. If a listing was not found, go to (2).

(2) Look in the TO 33K-1-100-2 to see if the item is identified with the base part number followed by

SERIES. If a SERIES entry is found verify that the manufacturer and noun match the item in question.

If these match, go to (3). If they do not match - submit a Calibration Determination Request (AFTO Form 45).

(3) Locate the 33K-series TO identified as the calibration authority for the SERIES entry. Ensure that the

33K-series TO Table 1 specifications encompass the specifications of the item in question. If the specifications are in agreement, STOP - the SERIES entry may be used and no Calibration Determination Request (AFTO Form 45) is required. If the specifications are not in agreement submit a Calibration Determination Request (AFTO Form 45).

1-3

1.2.3.4 When multiple part numbers appear on a unit and are also listed in TO 33K-1-100-2, the hierarchy for which part number to use is as follows:

a. Manufacturers part number.

b. Government assigned part number.

c. Military assigned part number.

d. Other identified part number.

When the TI is a kit or part of a test stand, apply this hierarchy to the complete assembly. For example: an aircraft tire kit, P/N 1064 is a P/N 1064 when all components are original. If a calibrated part is replaced with a different manufacturer’s part number the most accurate part number for the complete assembly becomes MILG8348SERIES.

This intent is to maintain the system specifications of the complete assembly.

Using individual part numbers may result in over/under specification.

For complex test stations, an AFTO Form 45 may be required to accurately list all the components of the test station.

For items that have two or more part numbers (manufacturer, military or government assigned), not all of which are listed in TO 33K-1-100-2, an AFTO Form 45 may be submitted for the unlisted part number(s). In the AFTO Form 45 remarks section clearly state the part number that is listed in TO 33K-1-100-2 so that the additional (unlisted) part number(s) can be properly referenced.

1.2.3.5 Items designated MIL may have more than one manufacturer. If this is the case, the calibration responsibility and/or 33K-series TO indicated in TO 33K-1-100-2, Calibration Requirements List, will be used regardless of the manufacturer. If the item is identified by MIL number and part number, the part number will take precedence.

1.2.3.6 Calibration responsibility for locally manufactured test and calibration aids; i.e., jigs, fixtures, adapters, loads, etc., will be determined jointly by the User and TMDE Flight Chief/PMEL Manager. Items within this category identified as not being TMDE will not require TMDE related certification or non-certification Labels. Conflicts in determinations will be submitted to AFMETCAL IAW Para 1.2.1.

1.2.3.7 Items designated as Automatic Data Processing Equipment (ADPE) are not considered TMDE and will not be listed in TO 33K-1-100-2.

1.2.4 New equipment entering the Air Force inventory may require calibration, see TO 00-20-14 and review Para 3.1 of this manual for guidance. Some equipment may require calibration methods similar to those used for items covered by existing 33K-series TOs. This equipment may not operate in the same ranges or parameters as those outlined in the existing TO. Activities requesting calibration determination should try using the appropriate TO and advise AFMETCAL if the techniques are satisfactory or if there are recommended changes. This will aid AFMETCAL in preparing revisions or new TOs. If an existing 33K-series TO is used, commercial data would still be the authority used until the equipment can be included in TO 33K-1-100-2 (Equipment Calibration Requirements List). Items listed in TO 33K-1-100-2 are not necessarily identified in the heading of the applicable TO. However, TO 33K-1-100-2 (Equipment Calibration Requirements List) identifies the applicable TO that will be used for accomplishing the calibration. If a published TO contains more than one set of accuracy specifications, the applicable specification will be identified in the NOMENCLATURE column by the abbreviation SSA (Same Specifications As).

1.2.5 The Air Force Primary Standards Laboratory (AFPSL) has facilities, equipment, and personnel to perform calibrations in special branches of the metrology science such as photometry, infrared, ultraviolet, and other applications of the electro-magnetic spectrum. This capability permits technical evaluation of equipment and its characteristics, resolution of technical problems, evaluation of techniques, and establishment of procedures for special application calibration support. The information required to establish a specific plan of calibration support is not always available at the time that special systems are introduced into Air Force inventory. PMEL representatives will contact AFMETCAL (see Para 1.2.1) whenever support is required in any of the special applications. Interim procedures will be developed to be used for the required support. The following will be provided:

a. Identification of TMDE and reference usage and requirements for calibration support.

b. Determination of measurement parameters and applicable tolerance requirements.

c. Determination of techniques and procedures to be used to accomplish the calibrations.

d. Assurance that there is a single point of contact with the National Institute for Standards and Technology

(NIST), traceability and standardization, and compatibility with the Air Force calibration program.

e. Evaluation of equipment capability to provide desired information.

f. Resolution of technical problems and assistance to personnel concerned with the special application calibration.

g. Determination of the feasibility of and provisions for the exchange of standards.

h. Determination of equipment to be calibrated at the AFPSL and scheduling of equipment to the laboratory.

1.2.6 TMDE listed in TO 33K-1-100-2 and CMSs has a Change Code (CC) field with a code that corresponds to the latest action or status of each entry. Change codes are listed in Table 1.1 below. Entries identified by a “D” code are valid entries. They will be deleted in subsequent technical order revisions unless requirements for retention are identified to AFMETCAL.

Table 1.1 Change Codes

Action Code Added A Changed C Not changed N Scheduled for deletion D Changed from NCR to scheduled Cal Interval P New TO being written T

1.2.7 Maintenance TOs are not normally listed in TO 33K-1-100-2. Official guidance to identify Maintenance TOs is provided in the Enhanced Technical Information Management System (ETIMS) Technical Order Catalog via the AF Portal.

1.3 ANALOG TI RESOLUTION.

Unless otherwise directed by the item specific calibration authority, if the TI resolution is such that the manufacturer’s stated accuracy cannot be realized, the TI shall be limited to the "next greater ½ division". This only applies when the TI reading is outside of the nearest ½ division less than the stated accuracy. If during calibration, the TI is found to be within the nearest ½ division less than the stated accuracy, the TI need not be limited.

Provided the dial can be read to ½ division, otherwise the gage is limited to the next greater division. An example when a gage cannot be read to ½ division is when the gage pointer is the same width as the distance between the gage division marks.

1-5/(1-6 Blank)

A limitation is not required if the TI is calibrated by adjusting the Standard for exact cardinal points on the TI, the indications are taken from the Standard, and the Standard (i.e. digital standard) used for the calibration has the resolution required to fully certify the TI.

Example: A 700 psi gage has an accuracy of 2.5% FS and is scaled in 10 psi divisions. The accuracy converts to

17.5 psi, which for this gage is 1¾ divisions. The standard is set to 200 psi, and the TI reads between 185 to 215 psi, i.e. within 1½ divisions. The gage is not limited. If the gage reads outside of 185 to 215 psi the gage is limited to the next higher ½ division than the reading, e.g., if the gage reads between 215 to 220 psi the gage is limited to the next higher ½ division i.e. to 2 divisions. Provided the dial can be read to ½ division, otherwise the gage is limited to the next greater division. An example of when a gage cannot be read to ½ division is when the gage pointer is the same width as the distance between the gage division marks.

1.4 DIGITAL TI RESOLUTION.

Unless otherwise directed by the item specific calibration authority, if the TI resolution is such that the manufacturer’s stated accuracy cannot be realized, the TI shall be limited to the next resolution. This only applies when the TI reading is outside of the smallest resolution less than the stated accuracy. If during calibration, the TI is found to be within the smallest resolution less than the stated accuracy, the TI need not be limited.

Example: An indicator that has an accuracy of 0.0016 and a resolution of 0.002 will be limited to an accuracy of 0.002.

A limitation is not required if the TI is calibrated by adjusting the Standard for exact cardinal points on the TI, the indications are taken from the Standard, and the Standard (i.e. digital standard) used for the calibration has the resolution required to fully certify the TI.

1.5 TYPICAL SPECIFICATIONS.

Manufacturer’s typical (or operational) specifications generally indicate the manufacturers expected performance of a given product. Typical specifications are not warranted or guaranteed by the manufacturer. Specifications listed as typical are not normally calibrated, unless directed through an official means such as technical order.

1.6 CALIBRATION OF TI WITH MULTIPLE ENGINEERING UNITS

Unless otherwise directed by the item specific calibration authority, if the TI has a digital readout with the ability to display multiple engineering units (e.g. inches and millimeters), it shall be calibrated to the engineering units as per AFCAV Table 1, CTO, or commercial data. All other engineering units are inherently calibrated. AFMETCAL has determined the risk is sufficiently low that a conversion error would exist and would result in significant measurement error.

If there is reason to believe there is a conversion error, other engineering units can be checked at a single cardinal point along the full-scale range of the TI during the calibration. Such a check can be performed at a stable test point while switching through the various engineering units and comparing the value to the calculated conversion.

Reference for conversions are in NIST Special Publication 811, 2008 Edition, Appendix B.9, which is posted on the AFMETCAL SharePoint.

SECTION 2

MAINTENANCE DATA COLLECTION CODES

2.1 GENERAL.

The Maintenance Data Collection (MDC) system codes contained in this TO are primarily for recording calibration and repair actions performed by Precision Measurement Equipment Laboratories (PMELs) on Test, Measurement and Diagnostic Equipment.

2.2 SECURITY.

When maintenance is being performed on classified equipment, the listing of a Work Unit Code could possibly lead to a breach of security, such as betrayed mission capability. Extreme caution should be exercised and, if any question exists, contact your local Operations Security Program Manager (OPSEC PM).

2.3 USE OF CODES.

It is necessary to use codes for recording PMEL actions into the MDC system. That data is entered into the PMEL Management Information System such as PAMS. The collected MDC data is used to produce reports in support of various management functions such as setting and adjusting calibration intervals for TMDE. PMELs shall document MDC in accordance with Appendix A.

2.3.1 The Standard Reporting Designator (SRD) consists of three alphanumeric characters and is used to identify equipment for MDC purposes. Typical PMEL used SRDs are "HPA" (Air Force TMDE), "HTE" (Air Force Equipment used in resident training) or "HPB" (non-Air Force TMDE).

2.3.2 The Work Unit Code (WUC) consists of five alpha numerical characters. WUCs listed in 33K-1-100-2 are assigned by AFMETCAL and are used to define TMDE calibration and repair responsibility. Otherwise, the applicable WUC listed in Section 3, Table 3.1, or Section 3, Table 3.2 will be utilized.

2.3.3 The Type Maintenance Codes, defined and listed in Table 2.1, consist of one alphabetic character and are used to identify the type of maintenance being performed.

2.3.4 The When Discovered Codes defined and listed in Table 2.2, consist of one alphabetic character and are used to describe when the discrepancy or maintenance requirement was discovered.

2.3.5 The Action Taken Code, Calibration Condition Received, and Calibration Condition Returned codes, defined and each listed in Tables 2.3, 2.4a, and 2.4b respectively, each consist of one alphabetic or numerical character and taken together are used for calibration interval analysis.

The combination of accurate Action Taken, Calibration Condition Received and Calibration Condition Returned Codes as recorded in the Maintenance Data Collection system is very important. The combination of these three fields is used for calibration interval analysis. Appendix A of this TO lists valid combinations of Action Taken, Calibration Condition Received (by the PMEL), and Calibration Condition Returned (to the owner) Codes. Once the Action Taken Code is selected, the selection of Calibration Condition Received Codes should be restricted. Once the Action Taken and Calibration Condition Received Codes are selected, the selection of Calibration Condition Returned Codes should be further restricted.

Example: If the Action Taken Code is K (Calibrated--Adjusted), the Calibration Condition Received Code is A (In Tolerance), and the Calibration Condition Returned Code is G (In Tolerance), we deduce that a minor adjustment (peak or tweak) was performed, but the item was within tolerance at the start of the calibration.

Collectively, Action Taken Code, Calibration Condition Received code, and Calibration Condition Return code identify a unit of work.

SECTION 3

TEST, MEASUREMENT, AND DIAGNOSTIC EQUIPMENT (TMDE) CALIBRATION

3.1 GENERAL CALIBRATION TECHNICAL ORDERS.

Calibration of TMDE involves an extensive variety of technical data. The following information will be used for the identification and use of TMDE technical data.

Some 33K-series calibration TOs reference the manufacturer’s specifications with statements such as "See Commercial Data" as the Table 1 Accuracy. End item Table 1 specifications for many of these items can be viewed in AFCAV as detailed in Section 7. Technicians are encouraged to submit vendor information to the AFMETCAL technical staff for the end items covered by those 33K-series calibration TOs which are listed as N/A in the Specifications field of AFCAV ("Specifications Not Posted"). Vendor information in the form of scanned pages commercial operations manual, facsimile from vendor, and/or websites linking to the operating specifications are preferred. If necessary send hard copies of vendor information to: AFMETCAL/WNM, Attn: Spec Data, 813 Irving-Wick Drive, Horton Building, Heath OH, 43056-1199. Scanned images or links to vendor specification web pages can be sent via email to:

AFMETCAL.K100.ELEC@us.af.mil or AFMETCAL.K100.MECH@us.af.mil (depending on the measurement area). For items listed as N/A ("Specifications Not Posted") continue to use local commercial data until the AFCAV data is updated.

3.1.1 Publication of TOs.

There are instances where two calibration TOs are listed for the same item. This occurs when new measurement technique TOs consolidate like items or when revisions to current publications using new standards or procedures are published. When new calibration TOs are distributed and new standards are available, the previous TOs will be rescinded.

3.1.2 General Calibration TOs.

General Calibration TOs are published to support similar items in one TO. Numerous items may be supported in this manner by grouping the value to be measured and the accuracy and range. TMDE that does not possess sufficient identifiable characteristics; i.e., manufacturer, type number, model number and/or stock number, will be calibrated according to these General Calibration TOs. A request for determination of calibration responsibility is not required for these items. If the accuracy cannot be determined, the User will specify the accuracy requirements. These will be treated as special calibrations. Use the corresponding WUC, Calibration Interval, and Calibration Responsibility for equipment supported by these General TOs.

3.2 SPECIFIC TMDE AND EQUIPMENT.

3.2.1 Aerospace Audio-Visual Services (AAVS) Video TMDE.

AAVS Video TMDE that is used to give visual indications of the video signal and is not used to broadcast or measure broadcast signals is not normally calibrated in the PMEL. The calibration support for this equipment will be mutually agreed to by the TMDE Flight Chief/PMEL Manager and the User. A calibration responsibility request will be submitted IAW TO 00-20-14 to resolve any disagreement.

3.2.2 Automatic Data Processing Equipment (ADPE).

ADPE is not considered TMDE and will not be listed in TO 33K-1-100-2.

3.2.3 Automotive Test Equipment.

Torque wrenches and the more sophisticated engine analyzing equipment that verify equipment performance factors, make absolute measurements, or affect safety are considered TMDE and calibration should be accomplished IAW published calibration determinations in TO 33K-1-100-2 or an appropriate CMS TO. Requests for calibration responsibility determination, AFTO Form 45, should be submitted if no calibration determination has been published and user applications do not allow NPC designation. Test equipment used solely for routine automotive support (tire gages, tach-dwell meters, compression testers, etc.) do not normally require calibration and requests for calibration responsibility determination should not be submitted for these items. If the User requires calibration for this equipment, calibration support will be mutually agreed to by the TMDE Flight Chief/PMEL Manager and the User.

3.2.4 Computer/PC Clock.

Computer/PC Clocks do not require calibration when used for program timing events; i.e., data printouts, delays, settling time, etc.

3.2.5 Electrical Meter.

The Electrical Meters referred to in the General Calibration TOs are those used for measuring voltage, current or other properties as an entity and not those incorporated in combination test sets such as multimeters. General Calibration TOs are being prepared in such a way that calibration may be accomplished with the standards presently available. Calibration TOs for panel meters will not be prepared because the applicable TO for the TMDE, subsystems, or facilities will include calibration of these items. Requests for determination of calibration responsibility should include the application and nomenclature of the end item on which the meter is a component part.

3.2.6 Fire Suppression Systems

TMDE installed in Fire Protection systems will be maintained, tested, and repaired in accordance with AFI 32-2001, Fire Emergency Services (FES) Program, Unified Facilities Criteria (UFC) 3-601-02, Operations and Maintenance:

Inspection, Testing, and Maintenance of Fire Protection Systems, and UFC 3-230-02, Operations and Maintenance:

Water Supply Systems. Pressure gauges utilized in the fire protection systems are common and used in other applications. AFTO Form 45s will be submitted on all individual gauges that are not listed in TO 33K-1-100-2. The calibration determination will be made as if it was a normal pressure gauge. The customer will need to identify to the PMEL if it is a Fire Protection Gauge. The PMEL will calibrate these gauges as a special calibration, assign Type Maintenance Code “S” and When Discovered Code “Q”. In the certification label remarks section put the interval of 120 months and make the due date NPC.

3.2.8 Gage Block Packing

All Gage Block sets will be pre-packed before they leave the laboratory to avoid damage of the Gage Blocks. The packaging includes oiling the Gage Blocks and placing packing inside the case to hold Gage Blocks in position. The case will then be taped shut both lengthwise and widthwise.

3.2.9 Gage Block Set.

The number of Gage Blocks in a set will be the part number for that Gage Block Set. All Gage Blocks sets, individual Gage Blocks, and Gage Block accessories will identify the manufacturer as Federal Specifications promulgated by GSA.

3.2.10 Gage Blocks and Gage Block Accessories Individual.

Gage Blocks and Gage Block Accessories are generally listed in the TO 33K-1-100-2 as sets. Individual Gage Blocks and Gage Block Accessories will not normally be listed in TO 33K-1-100-2. Refer to table 3.1 for individual Gage Blocks and Gage Block Accessories calibration information.

3.2.11 Gear Wire.

Gear Wires come in pairs and the individual pairs will not normally be listed in TO 33K-1-100-2. Refer to table 3.1 for Gear Wire pair calibration information.

3.2.12 Liquid in Glass (LIG) Thermometer(s).

LIG thermometers that are to be used for fuel accountability purposes shall be certified using the General Calibration TO at least once a year. Range and accuracy shall be supplied by the user (if not already listed in TO 33K-1-100-2) and annotated on the Certification Label. Part or type numbers for these LIG thermometers shall be listed in the TMDE Calibration Interval, Technical Order and Work Unit Code Reference Guide (33K-1-100-2) and the “Remarks” section shall indicate the thermometer is only to be calibrated if used for fuel accountability. Refer to TO 00-20-14, for further guidance, if needed, with special calibrations.

3.2.13 Medical Equipment (MED)/Unique Medical TMDE.

Equipment unique to the medical industry for patient care, first aid response or test equipment, designed exclusively to simulate human physiology to facilitate testing and calibration of patient care equipment. Some examples (not all inclusive) are: patient simulators, defibrillator analyzers, vital signs simulators, electrosurgical analyzers.

All equipment falling under this definition is managed under the AF Biomedical Engineering Maintenance Program by Biomedical Equipment Maintenance Technicians (BMETs) in accordance with AFIs 41-201 and 41-209. Medically unique equipment will be published in TO 33K-1-100-2 with the Cal TO, Cal Responsibility, and Cal Interval fields all marked as MED. Requests for calibration determinations (AFTO Form 45) may be submitted to AFMETCAL for a determination of Medical TMDE used in Medical Treatment Facilities (MTF). For further information regarding support of medical equipment/unique medical test equipment used in MTFs contact HAF AFMOA/SGALE (AF Clinical Engineering).

General purpose test equipment (not unique to the medical industry such as oscilloscopes, digital multimeters, frequency counters, etc.) used by BMETs to maintain and/or certify medical equipment/unique medical TMDE used in MTFs must be calibrated in accordance with AFI 21-113, TO 00-20-14 and TO 33K-1-100-2.
