secondary display) + AC Current (right secondary

display) Measurement

Warning

To avoid damages to the Meter or harms to you, do

you measure higher than AC voltage 600V rms and

AC current 1000A rms.

Frequency Measurement only measures the

current signal.

To test for Frequency Hz (main display) + AC Voltage

(left secondary display) + AC Current (right secondary

conductor.

The connecting method of 3 phases 4 wires, 3

phases 3 wires or single phase 2 wires, see figure

4, 5 and 6

When measuring 3 phase 4 wires: (see figure 26,

27, 28)

Press SELECT to choose the first phase 1, see
