CALIBRATION
The PQR D52 monitors are designed to test the Power Line with a high degree of accuracy. In
this unit all measurements are referenced to a state of the art, temperature compensated voltage
source. It is recommended that each unit be calibrated annually by the factory as certain
components may require calibration. The procedure typically takes seven days and will be
provided upon request for a nominal fee. Mention CALIBRATION PROCEDURE when
calling for an RMA number.
