7. Operating Basics
UT-P35&UT-P36 high voltage isolating 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. Guesstimate the voltage to measure and set the correct attenuation
switch. If the input voltage is over range, perhaps it will damage the
probe.
c. Connect the BNC output terminal to oscilloscope or other measuring
instrument. Connect the input cables to the adapt clips well.
d. Connect the AC adapter output to probe power input connector. The
green POWER indicator lights.
e. Select adapt attenuation range according to measured voltage. When
the measured voltage is over range, the red OVER RANGE
indicator lights, the attenuation should increase or disconnect the
power and the input measured voltage.
f. Set the measuring oscilloscope or other instrument sensitivity
according to displayed altitude of signal.
g. Connect the adapt clips to input cables.
h. Connect the clips to measured targets to start measuring. The probe
body should be far from high voltage pulse circuits to reduce the
noise or errors.
i. When the test is finished, disconnect the power at first, then
disconnect input from measured target, disconnect the output BNC
terminal from the oscilloscope or other measuring instrument at last.
