Testing with the PQR D52
The PQR D52 Single phase Voltage Power Quality Recorder is designed to obtain the
maximum amount of useful data from the circuit under test, while requiring the minimum
amount of setup time.
Data from the Hot, and the neutral line starts being collected as soon as power is applied to
the 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.
The PQR D52 will continuously test the Hot and Neutral inputs for Sags, Surges, Power
Failures, Dropouts, Impulses, High Frequency Noise, Line Frequency, and Phase changes.
Any power quality problems that exceed the preset thresholds will be recorded in FLASH
RAM, with the time and date stamp of the event. There is enough data storage capacity in the
unit to collect up to 32,000 of these readings.
