Model UT233: OPERATING MANUAL

E. Phase Angle (main display) + AC Voltage (left

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.

To test for Phase Angle (main display) + AC Voltage

(left secondary display) + AC Current (right secondary

display), connect the Meter as follows:

Press the MENU to select Phase Angle (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 23,

24, 25)

Press SELECT to choose the first phase 1,

see figure 23.

Figure 23

The triple displays shows the first phase value of

phase angle AC Voltage V and AC Current A.

Then press SELECT again to choose the second

phase 2, see figure 24.
