1736/1738 Users Manual 5. Use the Thin-Flexi current probes and plug the phase A current probe into the phase A/L1 input jack on the logger, the phase B/L2 current probe into the phase B/L2 input jack on the logger, and the phase C/L3 current probe into the phase C/L3 input jack on the logger. 6. Apply the iFlex Probes to the wires in the electrical panel. Make sure the arrow on the probe points to the load. 7. Connect the voltage test leads to neutral, phase A/L1, phase B/L2, and phase C/L3. 8. With all of the connections done, check that the voltages for phases A/L1, B/L2, and C/L3 are as expected. 9. Read the current measurements for phases A/L1, B/L2, C/L3, and N. 10. Push Verify Connection to check and correct the phase rotation, phase mapping, and polarity of current probes. Most installations use a clockwise rotation. 11. Push Live-Trend to display a chart of the last 7 minutes. 12. Push  to determine the power values, especially active power and power factor. 13. Push Live-Trend to display a chart of the last 7 minutes. 14. Push  for 3 seconds to take a snapshot of the measurements. 15. Push  and change the default configuration with Edit Setup. Typical setup: - 1 week duration - 1 minute for average calculation interval - 15 minutes for demand interval 16. Push Start Logging. You can review the live data with  or . Return to the active logging session with . Once the logging session is completed it is accessible in Memory/Settings - Logging Sessions. 17. Review the logged data using the softkeys V, A, Hz, +, Power, and Energy. See page 36 for more information. 18. To transfer and analyze the data using the PC software, attach the USB flash drive to the Logger and copy the logging session and screenshot. Note You can also use the USB cable or the USB WiFi dongle to transfer the measurement data. 50
