Page 6: Introduction
To monitor the AC line with the PQR D52, plug the line cord provided into a standard 110 volt or 220 volt outlet. After running an internal self test, the unit will start testing the Hot and Neutral line and the Temperature and Humidity. -
Page 7: Calibration
Page 7 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. -

AC power connector located on the back of the unit. Data will continue to be gathered until the unit is unplugged. Long term voltage testing is known as Data Logging. The PQR D52 samples the voltage on each of the 4 inputs continuously, and stores the average voltage once each minute. There is enough data storage capacity in the unit to collect these readings on all 4 input channels for up to 20 days at 1 minute per sample. - Page 10 Status LED Apply AC Power: There is a Unit Status LED on the front of the PQR D52. This led is used to indicate system diagnostics status, and Unit operational status. When the PQR D52 is first connected to AC power (110VAC or 220 VAC), it will go through a series of power on diagnostics.
