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, Canada, 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.

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’.
