Setting the test voltage for DC withstanding voltage testing
The test voltage to be applied to a DUT can be set to 0.00 k
V
through 10.5 k
V
DC
(at a resolution of 0.01 k
V
).
To make settings, use the rotary knob with the cursor at the test voltage.

v
oltage, press the F1 (
V
OLT) key (the
keys can also

3.
Using the rotary kno

, set a test
v
oltage.
• When settings are being made, if the test voltage multiplied by the upper reference
exceeds 55 W, “READY” disappears and “O
V
ER 55 W” flashes at the top right of
the LCD to indicate that testing cannot be performed. In such a case, reduce the
test voltage or the upper reference.
Turning the lower judgement function ON/OFF
The lower judgement function can be turned on/off.
When the lower judgement function is on, the test ends with a FAIL judgement if
the measured current drops below the lower reference. The lower reference is
explained in the following section.
You can set the lower judgement function to ON/OFF using the SHIFT + F2 keys,
regardless of the location of the cursor. Each time the SHIFT + F2 keys are pressed,
ON and OFF alternate.
The
keys can also be used to move the cursor to ON/OFF of the lower
judgement function. If the cursor is at ON/OFF of the lower judgement function, the
rotary knob can be used to make settings.
