Test Leads – Markings

The 1744/1743 Logger includes built-in, labeled test leads for voltage terminals L1 or A, L2 or B, L3 or C, and N, as well as two for the internal power supply. The Flexi Set or current clamp sets are connected by a seven-pin plug to the Logger. Color coding clips are provided for your convenience.

Connecting Current Probes

Connect current clamps and Flexi Set probes so that current will flow in the direction marked by arrows on the probes. Current must flow from the energy generator to the energy consumer (the load) in order to maintain a positive active power. (The polarization of the test lead for neutral conductor current is not significant, because the phase angle of the neutral conductor current is not evaluated.)

Note

Make sure the clip-on probes are connected to the appropriate phase:

VL1 with IL1 for a P-N measurement or VL12 with IL1 for a P-P measurement.
