First Measurements

At the measurement site, look at the information in the panel and the rating plates on the
machines. Based on knowledge of the electrical supply in the facility, determine the
configuration. The example below performs a measurement on a three-phase wye system.
To set up the Analyzer:
1. Connect the Analyzer to mains power. The Analyzer starts and shows the Main Menu.
See Measurement Line Power Source if you want to power the Analyzer from the
measurement line.
2. In the Main Menu, select the measurement mode as PQ Meter.
The connection verification display shows the voltage, current and frequency readings.
3. Push Topology to configure the three-phase wye and the nominal voltage.
4. Use the cable end with the short fan-out of the 3-phase + N voltage test lead and connect
A/L1, B/L2, C/L3, and N into the Analyzer.
5. Connect the voltage test leads to phase A/L1, B/L2, C/L3, and Neutral.
6. Connect the green test lead into the Analyzer.
7. Connect the green test lead to a good ground source, such as a bare, uncoated part of the
cabinet. Ideally, a grounding lug in the panel.
8. With all of the connections done, check that the voltages for phases A/L1, B/L2, C/L3, and
Neutral to Ground are as expected.
9. Connect the Thin-Flexi current probes to the Analyzer:
Phase A/L1 current probe into the phase A/L1 input jack

Phase B/L2 current probe into the phase B/L2 input jack

Phase C/L3 current probe into the phase C/L3 input jack

N (neutral current) probe into the N input jack

To measure the system:
1. Apply the iFlex Probes to the wires in the electrical panel. Make sure the arrow on the probe
points to the load.
