The lower reference can be set to 0.01 MΩ
through 9.99 GΩ (at a resolution of 0.01 MΩ
for the 0.01 MΩ to 9.99 MΩ range, 0.1 MΩ for
the 10.0 MΩ to 99.9 MΩ range, 1 MΩ for the
100 MΩ to 999 MΩ range, and 0.01 GΩ for the
1.00 GΩ to 9.99 GΩ range), but below the max-
imum rated current.
When a resistance value at or below the lower
reference is detected following a wait time, the
test ends with a FAIL judgement.
•
With the lower judgement function on, if set-
NOTE
tings are made so that the test voltage divided
by the lower reference exceeds 1.1 mA,
"READY" disappears and "OVER 1.1 mA"
flashes at the top right of the LCD to indicate
that testing cannot be performed. In case of
the test voltage setting exceeding 1020 V on
TOS9213AS, however, "OVER 0.11 mA"
flashes when the test voltage divided by the
lower reference exceeds 0.11 mA. In either
case, lower the test voltage or raise the lower
reference.
•
No lower judgement is made until the WAIT
TIME has elapsed.
When the cursor is at the lower reference, the rotary knob can be used to make settings.

NOTE
• With both the upper and lower judgement functions on, if the lower reference is
set at or above the upper reference, "READY" disappears and "UP<=LOW"
flashes at the top right of the LCD to indicate that testing cannot be performed.
Reduce the lower reference or raise the upper reference.
• To measure the resistance even when it results in a decrease in the test voltage,
turn off the low judgement. In such a case, if the output voltage deviated from the
range of the output-voltage monitor function by ±(10% of the setting + 50 V), the
measured voltage flashes on the LCD voltmeter to warn of a decrease in the test
voltage. The test can still be conducted, however.

Resistance value-based judgment
To display the lower reference, press the F2 key (LOWER). (When the
lower reference is displayed, the cursor can be moved using the
keys.)
You can select resistance value-based judgement or current value-
based judgement by pressing SHIFT+F4.
Pressing SHIFT+F4 causes the currently selected option to switch between
resistance (R) and current (I) and causes the units that are displayed on the
screen to change.
Using the keys, move the cursor to the target digit.
Using the rotary knob, set the lower reference.
Current value-based judgment
The lower reference can be set to 0.1 µA
through 1.00 mA (at a resolution of 0.1 µA for
the 0.1 µA to 99.9 µA range, 1 µA for the 100
µA to 1.00 mA range).
After testing starts and the testing voltage is
reached, if a current value at or below the lower
reference is detected, the test ends with a FAIL
judgement.
•
No lower judgement is made during the volt-
age rise time.
