Model UT233: OPERATING MANUAL

Reactive Power (main display) + AC Voltage (left

secondary display) + AC Current (right secondary

display) Measurement

Warning

Press the MENU to select Reactive Power (main

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

Current (right secondary display) range.

Press the lever to open the transformer jaw, and

When measuring 3 phase 4 wires: (see figure 17,

18, 19)

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

(left secondary display) + AC Current (right secondary

display), connect the Meter as follows:

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.

Press SELECT to choose the first phase

see figure 17.

Figure 17

The triple displays shows the first phase value

of reactive power Kvar, AC voltage V and AC

current A.

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

you measure higher than AC voltage 600V rms and

AC current 1000A rms.
