Input Connections
The Analyzer has 4 BNC-inputs for current clamps and 5 banana-inputs for voltages.
Self-adhesive decals are supplied corresponding to wiring color codes used in the USA, Continental Europe, the UK, and China. Stick the decals that fit to your local wiring codes around the current and voltage inputs.
De-energize power systems before making connections whenever possible. Avoid working alone and work according to the warnings listed in section ‘Safety Information’.
For a 3-phase system make the connections as shown in Figure 1. First put the current clamps around the conductors of phase A (L1), B (L2), C (L3), and N(eutral). The clamps are marked with an arrow indicating the correct signal polarity.
Next make the voltage connections: start with Ground and then in succession N, A (L1), B (L2), and C (L3). For correct measuring results, always connect the Ground input. Always double-check the connections. Make sure that current clamps are secured and completely closed around the conductors.

distribution system
For single phase measurements, use current input A (L1) and the voltage inputs Ground, N(eutral), and phase A (L1).
A (L1) is the reference phase for all measurements.
Before making any measurements, set the Analyzer up for the line voltage, frequency, and wiring configuration of the power system you want to measure. This is explained in section ‘Setting up the Analyzer’.
