Page 4: Introduction
Power Quality (IEC 61000-4-30 Class A) The PQPro™ is an 8 channel power quality analyzer / data recorder. It monitors three phases of voltage and current as well as a fourth channel of voltage and current. Measured parameters are updated every ½... -
Page 5: Safety
Please read and UNDERSTAND the following information before operating this instrument ▪ The PQPro™ uses a membrane keypad that could be damaged if a sharp object is brought into contact with it. ▪ Frequently inspect the test leads and the instrument for damage. If the instrument shows any signs of physical damage or functions improperly, it should not be used. -
Page 6: Quick Start
PQPro™ User Manual Quick Start Connecting the PQPro™ to the circuit to be measured is a straightforward process. 1. Connect the voltage leads for each phase to be measured. For proper operation V1 must always be used. Three phase circuits can be connected in either a ‘wye’ or 'delta’ configuration. Refer to the ‘Hookup Configurations’... -

PQPro™ User Manual Hookup Configurations The PQPro™ can be used to monitor any single phase or three phase power configuration. Following are descriptions of the five most common field setups: - 4 -... -
Page 8: Hookup Diagnostic Warnings
PQPro™ User Manual Hookup Diagnostic Warnings From the ‘RECORD’ screen the operator can select ‘SYSTEM CHECK’. The instrument does a number of checks on the connected signals, if it detects a potential problem a message will be displayed in the RECORD screen. - Page 9 PQPro™ User Manual ‘-VE POWER CHECK CT1’ ‘-VE POWER CHECK CT2’ ‘-VE POWER CHECK CT3’ ‘-VE POWER CHECK CT4’ This usually means that the relevant CT has been connected in reverse. To fix the problem remove the CT, rotate it 180 degrees, reconnect it and then press ‘SYSTEM CHECK’ again. In some cases this is not an error (i.e.

RMS and Waveform Data Storage The PQPro™ stores RMS data at set intervals which can be adjusted from 0.2 (continuous) to 30 seconds or 1 to 30 minutes. The minimum, maximum and average values are stored at the end of each storage interval. -
Page 11: Interharmonics
PQPro™ User Manual Interharmonics Interharmonics are calculated by the software from the waveform snapshots that are stored every storage interval. The Interharmonic calculation requires multiple cycles of waveforms. If Interharmonics are turned off only one cycle of waveforms is captured and the software can only calculate the harmonics. -
Page 12: Under/Over Voltage Events
½ cycle resolution, for events less then 2 seconds and in seconds for longer events. The PQPro™ uses a hysteresis value of 0.1% of full scale to determine when the event has finished. For example if the under voltage trigger level is set at 228.0 volts the instrument will start recording an event when the voltage goes under 228.0 volts and will stop recording the event... -

PQPro™ User Manual PQPro™ Front Panel The front panel of the PQPro™ has a colour graphics display, a 10 button keypad and a memory card interface. The colour graphics display is 270x480 pixels. The keypad has two types of buttons. The bottom row of 4 keys are fixed function buttons and the top row of 6 keys are function keys that change function depending on the active screen on the display. -

When it detects a card being inserted (or a card in the socket immediately after power up) the instrument checks the card size and the number of files on the card. The PQPro™ supports from 2GB to 64GB SD memory cards. Each file is allocated approximately 0.5GB on the card so that a 2GB card can hold up to 4 data files and a 64GB card can hold up to 128 data files. -
