TOS9200/9201 Basic Operations 3-21
3.5.1 Settings on the DCW1 screen
Setting the test voltage for DC withstanding voltage testing
The test voltage to be applied to a DUT can be set to DC 0.00 kV through 6.10 kV
(at a resolution of 0.01 kV).
To make settings, use the rotary knob with the cursor at the test voltage.
1. To bring the cursor to the test voltage, press the F1 (VOLT) key (the
keys can also be used).
2. Using the keys, move the cursor to the target digit.
3. Using the rotary knob, set a test voltage.
• When settings are being made, if the test voltage multiplied by the upper current
exceeds 55 W, “READY” disappears and “OVER 55 W” fl ashes 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 current.
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 current. The lower current is explained
in the following section.
The lower judgement function can be set 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.
