Legend of displayed symbols:
WITHSTANDING VOLTAGE DC
Name of selected function
SETTING PARAMETERS:
Ustart
2000
V
Start test voltage, step = 25 V
Ustop
7000
V
Stop test voltage, step = 25 V
Tstep 00min 00s
Duration of test voltage per one step
Tend 01min 00s
Duration of constant test voltage after reaching
stop value
Itrigg 1.500mA
Set trigger leakage current, step = 10 A
Setting up parameters for Withstanding Voltage:
- Press the SELECT key, (the set-up menu (Fig. 29)
appears on the display).
- Select the parameter (line) to be set using the  and 
keys;
- Adjust the parameter using the  and  keys or skip
to the next sub-parameter by pressing the SELECT
key.
- Complete the parameter adjustments by pressing
either the ESC or the START/STOP key (to run the
measurement directly). The settings displayed last will
be saved.

Withstanding Voltage function
Tstep and Tend are independent timers. The maximum time for each timer is 30 min
60 s. Tend begins after the completion of the ramp period. Ramp period can be
calculated from:
Tramp  Tstep(Ustop – Ustart) / 25 V
If Tstep is set to 00min 00s, then the ramp voltage increases by approximately 25 V
every 2s.
