Standby
status
Push ‘CLOCK’, ‘TIMER’ button to
select STEP 2.50kVSET, STEP5.00
kVSET.
Tips
Note 1: Data of the last step is held and displayed (HOLD symbol is lit up).
Note 2: When TC symbol is displayed (under the temp. compensation mode), the tester cannot conduct test under the mode
of step-voltage measurement.
Note 3: If you need to check the set voltage during measurement, just push ‘ ’ button, and the set voltage will be displayed
for about 2 seconds; At the end of measurement, push ‘ ’ button to switch between the last input voltage and the last
measured voltage.
Operation procedures:
Push ‘MEASURE’ and hold it
>1s to start step-voltage test.
Use ‘ ’,‘ ’ button to adjust
the test voltage to 5 kV.
Test voltage increases in preset steps,
and afterwards the test will be
automatically stopped.
Push ‘ ’ button, and the
set test voltage will flash.
Push ‘Enter’ button to switch to mode
of step-voltage test, and ‘Step’ symbol
