Calibration

Recalibration is an excellent way to be sure that the Detector Calibrator has not been damaged. If damage is found, the Calibrator can be repaired and restored to its original accuracy.  We can recertify the factory calibration of the Calibrators in all Biddle PD Detectors [17000, 27000, & 37000] and 6617250 series Master Calibrators.  HV Test Technology uses the same calibration procedures as originally used by the Biddle factory before shipment of new P.D. Detectors.  We have equivalent instruments to those used by the factory and keep those instruments recertified on an annual basis with a Calibration Lab that uses NIST traceable instruments.  We are issued a Certificate of Calibration with NIST Traceability for our instruments annually.  We supply a NIST traceable Certificate with our recalibrations of client’s instruments. 

In the course of recalibration, the calibrator rise-time is checked.  If it does not meet the original Biddle spec, this is an indication of failing components.  We can replace these components and restore the calibrator signal rise-time to Biddle specs, or the more demanding IEC 60270 requirements.
