Warning

Press SELECT to choose the first phase

1, see

figure 14.

The triple displays shows the first phase value

of apparent power kVA, AC voltage V and AC

current A..

Then press SELECT again to choose the second

phase

2, see figure 15.

4.Apparent Power (main display) + AC Voltage (left

secondary display) + AC Current (right secondary

display) Measurement

To avoid damages to the Meter or harms to you,

do you measure higher than AC voltage 600V rms

and AC current 1000A rms.

To test for Apparent Power (main display) + AC Voltage

(left secondary display) + AC Current (right secondary

display), connect the Meter as follows:

Press the MENU to select Apparent Power (main

display) + AC Voltage (left secondary display) + AC

Current (right secondary display) range.

Press the lever to open the transformer jaw, and

clamp them to the corrresponding phase of tested

conductor. If user needs to mesaure any phase of

the 3 phase, then clamp them to that phase’s

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 14,
