7. Operating Basics
UT-P43&UT-P44 series current probe is very convenient to operate.
But we suggest every new user should read the manual perfectly prior to
begin operating.
7-1 Operation steps
a. Check and affirm the AC adapter input voltage is correct prior to
use.
b.
To get accurate measuring result, degauss and balance the probe

with the arrow on the probe jaw.
d.
After complete the previous steps, power on the wire circuit.
e.
Adjust the oscilloscope to display the signal.
f.
When the measure is over, power off the wire circuit, then open the
