3.4 Transducer Adjustment: If the VSK has the ability to be adjusted beyond zero adjustment, such adjustments procedures will be provided.

3.5 Zero Adjustment: The VSK shall have capability to zero the transducer(s) by push button either on the transducer(s) or gauge display.

3.6 Stand-alone Operation: All functions of the transducer shall be integrated; no gauge display shall be required to operate the transducer.

4.0 Physical/Mechanical Requirements

4.1 Dimensions and Weight: The VSK transducer shall measure no greater than 8 in x 5 in x 5 in and shall not exceed 5 lbs. The VSK gauge display shall measure no greater than 12 in x 6 in x 6 in and shall not exceed 5 lbs.

4.2 Ancillary Components: The VSK shall consist of the following necessary cables to connect all components, at a minimum: All cables shall be at least 5 feet in length

4.2.1 Communication cable from gauge display to computer

4.2.2 Communication/power cable from each transducer(s) to computer (this cable is used for stand-alone transducer operation when connected to a computer)

4.2.3 Cables to connect the transducer(s) to the gauge controller

4.2.4 Power cable for gauge display

4.3 Material: All components directly associated with the vacuum gas shall be made of a corrosion resistant material.

4.4 Design and Construction: The VSK shall be designed and constructed of materials that meet the requirements of this specification and in accordance with the best practices for industry approved equipment. It shall be the contractor's responsibility to assure the government that such design objectives as reliability, accuracy of operation, maintainability, and ease of operation have been given due consideration in the manufacture of this equipment. All parts shall so work together that the equipment shall supply the rated requirements without unnecessary strains, vibrations, and overheating. They shall be able to withstand the conditions met in shipping, storage, installation, and services. · All materials and parts of this equipment shall be capable of withstanding environmental testing requirements of this specification.

4.5 Power Requirements: The VSK shall operate on line power of approximately 120 VAC, 50/60 Hz source.

4.5.1 Safety: Documentation shall be provided to support the means by which electrical safety considerations have been addressed. This documentation shall consist of a minimum of a citation of a UL or ANSI identified standard or equivalent United States Standard to which the equipment conforms.
