Product Number 3130-001 7
We certify that the above product has been tested and found to conform to the product specification, priorto dispatch
from GenRad. The measurements performed by this equipment are traceable to international measurement
standards. Calibration records, including the date of calibration and the serial numbers of the measurement
instruments are maintained by GenRad and are traceable through the PDU System serial number.
NOTE: The PDU will not require any periodic adjustment in order to maintain specified measurement accuracy.
Calibration Measurements
Ambient temperature during calibration 20±1 °C.
The test resistances in the table below are applied between the red and black probes. The PDU is set to measure
resistance between these probes using the D M M function. The PDU reading must be between the limits shown.
