6.8 WITHSTANDING VOLTAGE TEST
6.8.1 Setting
of
parameters
1. Switch on the instrument by pressing the
ON/OFF
key
2. Select with arrow keys
or
the item “WITHSTANDING VOLTAGE DC” on main
menu and confirm with
SELECT
key. The screen of Fig. 43 is shown by the meter
Fig. 43: Initial screen withstanding test
Fig. 44: Final screen withstanding test
3. Press again the
SELECT
key to enter in the setup parameters section. The screen of
Fig. 45 is shown by the meter
Fig. 45: Setting parameters
4. Use the arrow keys
or
for the selection of parameters. The herewith Table 9
shows the meaning of the measurement parameters
5. Set the values by using the arrow keys
or
. Press
SELECT
key to select possible
sub-parameters and repeat the settings
6. Press
ESC
key to save the settings and back to the measurement screen or the
START/STOP
key to exit from the settings menu and activate the test
Parameter Description
Ustart
Start test voltage – Range
500V
10kV
step 25V
Ustop
Stop test voltage – Range
500V
10kV
step 25V
Itrigg
Set trigger leakage current – Range
0.001mA
5mA
step 10
A
Tstep
Duration of test voltage per one step
Tend
Duration of constant test voltage after reaching stop value
Table 9: Setting of internal parameters
CAUTION
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:
Ttot-ramp
Tstep * [(Ustop-Ustart) / 25V]
If Tstep is set to 00min 00s, then the ramp voltage increases by
approximately 25 V every 2s
