TOS9200/9201 Basic Operations 3-33
3.6.1 Settings on the IR1 screen
Setting the insulation resistance test voltage
The test voltage to be applied to a DUT can be set to DC –10 V through –1020 V (at
a resolution of 1 V). (The negative (-) mark is not displayed.)
To make setting, use the rotary knob with the cursor at the test voltage.
1. To move the cursor to the test voltage, press the F1 key (VOLT). (The
keys can also be used.)
2. Using the keys, move the cursor to the target digit.
3. Using the rotary knob, set the test voltage.
• With the lower judgement function on, if the test voltage divided by the lower
resistance exceeds 1.1 mA, “READY” disappears and “OVER 1.1 mA” fl ashes at
the top right of the LCD to indicate that testing cannot be performed.
In such a case, lower the test voltage or raise the lower resistance.
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 insulation resistance drops below the lower resistance.
The lower resistance is explained in the following section.
If the lower judgement function is off, the test ends without a FAIL judgement.
