Model UT233: OPERATING MANUAL
D. Power Factor cos (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 Power Factor (main display) + AC Voltage
(left secondary display) + AC Current (right secondary
display), connect the Meter as follows:
1. Press the MENU to select Power Factor (main display)
+ AC Voltage (left secondary display) + AC Current
(right secondary display) range.
2. 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.
3. The connecting method of 3 phases 4 wires, 3 phases
3 wires or single phase 2 wires, see figure 4, 5 and
6.
4. When measuring 3 phase 4 wires: (see figure 20,
21, 22)
Press SELECT to choose the first phase
1,
see figure 20.
Figure 20
The triple displays shows the first phase value of
power factor cos
, AC Voltage V and AC Current
A.
Then press SELECT again to choose the second
phase 2, see figure 21.
