Model UT231: OPERATING MANUAL

20

To avoid damages to the Meter or harms to you, do
you measure higher than AC voltage 600V rms and
AC current 1000A rms.

Warning

To test for Apparent power (main display) + Reactive
power (secondary display), connect the Meter as follows:

Press the 

MENU

 to select Power factor (main

display) + Phase angle (secondary display) range.
Press the lever to open the transformer jaw, and
clamp them to the power source or the tested
conductor.
Insert the red test lead to 

V

 input terminal and black

test lead to

 COM

 input terminal and connect them

to tbe live wire and neutrual wire of the tested circuit.
The double display shows the power factor value
and the phase angle value of the measured object.
When the power factor value is negative, it means
the loading is capacItive.
When the power factor value is positive, it means
the loading is inductive.
