TMDE Certification_TRANSCAT.pdf

These are Certificates of Calibration issued by Transcat, Inc. for various electrical and electronic testing equipment belonging to a company located at 3010 Santa Fe Court, Missoula, MT 59808 under Purchase Order XT-PO-001. The certificates document calibration services performed on multiple instruments between April and June 2026, all conforming to ISO/IEC 17025:2017, ANSI/NCSL Z540-1-1994, ISO 9001:2015, and ISO 10012:2003 standards.

The equipment calibrated includes transformer ratio test sets (Model TTR3-ADV and TTR310), an ohmmeter (Model MTO330A), a voltage measurement device (Model VIDAR), and a digiphone/underground cable fault locator (Model DIGIPHONE), along with associated reference standards including decade transformers, temperature and humidity data loggers, digital multimeters, resistors, and current shunts. Seven certificates show passing results with various test points ranging from low-voltage and resistance measurements to transformer ratio testing and excitation current verification. Two certificates document equipment failures: a digiphone with excessive corrosion in the battery holder requiring repair, and an MRCT unit with a damaged display unable to perform calibration. All calibrations were performed at either onsite or lab locations with calibration dates typically 30-45 days prior to due dates in 2026 and 2027, and all testing was conducted under manufacturer specifications using manufacturer procedures with environmental conditions documented for each calibration event.
