Page 5: Introduction
• Flicker (IEC 868 / IEC 61000-4-15) - Optional The PowerPro is an 8 channel power quality data logger. It can monitor 3 phases of voltage and current as well as a neutral voltage and current. Measured parameters are updated every ½ cycle to ensure that nothing is missed. -
Page 6: Safety
Please read and UNDERSTAND the following information before operating this instrument • The PowerPro uses a membrane keypad that could be damaged if a sharp object is brought into contact with it. This may expose the operator to potentially hazardous voltages. -
Page 7: Quick Start
PowerPro with PowerFlow Firmware Quick Start Connecting the PowerPro 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’... - Page 8 PowerPro with PowerFlow Firmware Quick Start continued 8. To stop logging press the ‘RECORD’ key and then F4 followed by F1 to confirm the stop command. Note: Static discharges may occur when connecting leads, communication cable or memory card, depending on environmental conditions.

Page 11: Hookup Diagnostic Warnings
PowerPro with PowerFlow Firmware Hookup Diagnostic Warnings Before the logger starts recording it does a number of checks on the connected signals, if it detects a potential problem a message is displayed and the operator must select either ‘Retry’ or ‘Ignore’ – if the operator presses ‘ESC’, ‘SETUP’, ‘DISPLAY’... - Page 12 PowerPro with PowerFlow Firmware Hookup Diagnostic Warnings continued ‘V3 Inverted’ -Voltage leads on channel three are reversed. ‘-ve Power Check CT#1’ ‘-ve Power Check CT#2’ ‘-ve Power Check CT#3’ -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 ‘Retry’.
- Page 13 PowerPro with PowerFlow Firmware Hookup Diagnostic Warnings continued ‘Volt Event Triggered’ -This indicates that an under/over voltage condition is active. This may indicate that the trigger levels are not set up properly (to view them press ‘SETUP’ and ‘F2’).

Page 14: Power Flow Firmware Features
Power Flow Firmware Features RMS Data Storage The PowerPro stores RMS data at set intervals which can be adjusted from 1 to 30 seconds or 1 to 30 minutes. The minimum, maximum and average values are stored at the end of each storage interval. The averaged values are calculated from the sum of the RMS values (updated every ½... -

Page 18: Logger Operation
PowerPro with PowerFlow Firmware Logger Operation Turning On and Off The PowePro should be put into low power (or sleep) mode when not in use. In low power mode only the real time clock and keypad interface are active. Current consumption from the battery is reduced to less than 100 microamps. - Page 19 PowerPro with PowerFlow Firmware Logger Operation (Memory Card) When the logger detects a card being removed it changes the screen to the initial screen if the logger was not recording. If the logger was recording when the memory card is removed it displays an error message: ‘RAM Card Error Please Re-Insert RAM Card...

Page 20: Setup
PowerPro with PowerFlow Firmware Logger Operation Setup Pressing the ‘SETUP’ button calls up the main setup screen. From the main setup screen you can select ‘LOGGING SETUP’, ‘TRIGGER LEVELS’, ‘FLICKER SETUP’, ‘SCALE FACTOR’, ‘SYSTEM SETUP’ or ‘COMM SETUP’. If a computer is connected to the serial port, then run PowerView software and select 'Logger' and 'Configure' to check and modify any of the setup parameters. -

PowerPro with PowerFlow Firmware Logger Operation (Setup - Logging setup) Connection Type (1P2W, 1P3W, 3P3W, 3P4W and 2.5E) This allows the logger to be configured for the five most common configuration types: 1P2W 1 Phase 2 Wire 1P3W 1 Phase 3 Wire (Edison circuit) -
Page 22: Line Frequency
PowerPro with PowerFlow Firmware Logger Operation (Setup - Trigger Setup) continued Line Frequency This allows the operator to set the nominal line frequency (50 or 60 hertz). The under/over frequency levels are automatically adjusted as a fixed offset from this value. For example, if the nominal line frequency is 60 Hz with an over frequency setting of 60.50 Hz and the... -
Page 23: Over Frequency
–0.10 Hz, -0.25Hz, -0.50 Hz and -1.00 Flicker Setup Flicker firmware is optional. If the PowerPro does not have Flicker firmware installed this menu will not appear. Setting up the flicker parameters involves setting the short term flicker calculation interval (PST), the long term flicker calculation interval (PLT) and the nominal line voltage. -
Page 24: Line Voltage
Ext PT To measure voltages greater than 750V external PT's must be used. The ratio of the external PT is entered here so that the PowerPro can display primary side values. The maximum ratio that can be entered is 200:1. If this is not sufficient the PowerView software can change this ratio after the data is transferred to the computer. -
Page 25: Neutral Ct
Setup Lock The operator must enter the lock code to enable or disable the setup lock. This code is the same for all PowerPro loggers and is not user changeable. The code is ‘4123’. Turning the lock on inhibits any changes to the setup parameters. -
Page 26: Calibration
PowerPro with PowerFlow Firmware Logger Operation (Setup – System Setup) continued Calibration Voltage, current, power and frequency readings can be calibrated. Before accessing this menu a 6 digit calibration lock password must be entered. Once this password is entered it will stay in effect until the logger is turned off (ie. -
