INTRODUCTION
This reference guide is designed to aid PQR D52 users in the interpretation of AC power line
problems.
The PQR D52 monitor is made in the U.S.A. by PowerTronics. This unit will detect a wide
range of power disturbances including spikes, sags, surges, common mode noise, dropouts, and
high frequency noise on the Hot and Neutral line. The PQR D52 will also monitor Temperature
and Humidity
The PQR D52 is one of a series of practical power line monitors, designed and priced to be
outfitted to everyone who services or installs three phase electrical, and electronic equipment.
Electronic equipment is damaged more often by power disturbances than by fire, theft, and
vandalism combined. Intermittent power problems are the most expensive hidden expense to
the owners of microprocessor based equipment.
The PQR D52 is easy to use and provides immediate and long term information for the
technician and customer to understand power line disturbances.
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.

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.

Monitor 2 AC Channels
Hot and Neutral + Humidity and Temperature
 User - Friendly
 Programmable
 Multiple Phase Monitoring
 Fast Impulse Detection
 Easy to Understand Reports
 Made in USA
The PQR D52 Power Line Analyzer provides a
complete analysis of your AC Power for a fraction of the
cost of other Monitors.
Disturbances detected on the Hot and Neutral Lines ,
as well as Temperature and Humidity channels are
recorded by their time, date, magnitude, and duration in a
non-volatile RAM memory. This data is then retrieved
from the analyzer through it’s serial communications
port.
The power to operate the unit comes from any
standard 110v / 220v AC outlet. Once plugged in, the
PQR D52 immediately begins testing the signals on the
input connectors.
Features
 Measures all types of disturbances
* Spikes * AC Voltage
* Sags * Common Mode Noise
* Line Frequency * High Frequency Noise
* Dropouts * Power Failures
* Surges * Temperature
* Humidity
 Simple to operate
1) Plug the power cord into a grounded outlet
2) Periodically connect to a computer for reports
 Stores Disturbance events in non-volatile RAM
* 32,000 Events in all
* Will Data log all channels up to 32,000 readings
(22.75 Days @ 1 sample per minute)
In addition to full Text Detail and
Summary reports, event information
such as the Magnitude, Time, and
Date of each of the disturbances is
also reported.
GRAPHICS SOFTWARE
INCLUDED!
Provided with the PQR D52 is the PQR
HOST COMMUNICATIONS Software.
This software allows you to easily download
the data and display or print the DATALOG
chart over time, the PIE CHART of the
summary of events or the HISTOGRAM of
the detail of events.

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.

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. The status of these tests can be seen in the Status
LED located on the front panel. While the initial tests are being executed, (approximately
10 seconds long) the Red LED will be blinking. After the tests are completed, the LED will
turn off briefly, and then turn on steady.
The LED will blink for ten seconds, whenever there is a disturbance detected on any input,
or the serial port has been accessed.
As soon as the diagnostics have completed, the PQR D52 is on-line, and monitoring the Hot
and Neutral lines, the Temperature channel, and the Humidity Channel. The unit should be
left on-line testing for at least a 72 hour period.

Connecting to the PQR D52
USB:
The USB port on the back of the PQR D52 can be directly connected to the
USB port on your computer. The PQR D52 will register on the USB port
as an additional communications port (COM X)
The USB driver for this port is a standard part of Windows ™ XP, Vista and Seven operating
systems. The driver is also available from the help desk at www.powertronics.com
Connect to the USB port using the USB A/B cable provided with the unit.
RS232 Port:
Some computers are equipped with an RS232 port and the PQR D52 is
enabled for communications with this port as well. (Note, only one port
on the PQR D52 can be utilized at a time).
The serial port connector on the back of the PQR D52 is a 9 pin DB style RS232. The pinout is
as follows:
Pin 2 Receive Data
Pin 3 Transmit Data
Pin 5 Ground
A Null modem cable (provided) must be used to establish a connection between this port and a
PC. This type of cable connects the Transmit Data pin on the PC to the Receive Data pin on the
PQR D52, and the Transmit Data pin on the PQR D52 to the Receive Data pin on the PC. It also
connects the Ground pins together.
Connect to the RS232 port using the Null modem cable provided with the unit.
The PQR D52 is configured to operate at 19,200 baud, with 8 data bits, 1 stop bit, and no parity
checking. Select Xon/Xoff Communications protocol.
