When the cursor is at the lower reference, the rotary knob can be used to make settings.

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 rotary kno
b
, set the lo
w
er reference.
• 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 s 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.

The lower reference can be set to 0.01 M
Ω
through 9.99 G
Ω
(at a resolution of 0.01 M
Ω
for the 0.01 M
Ω
to 9.99 M
Ω
range, 0.1 M
Ω
for
the 10.0 M
Ω
to 99.9 M
Ω
range, 1 M
Ω
for the
100 M
Ω
to 999 M
Ω
range, and 0.01 G
Ω
for the
1.00 G
Ω
to 9.99 G
Ω
range), but below the max-
imum rated current.
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).
When a resistance value at or below the lower
reference is detected following a wait time, the
test ends with a FAIL judgement.
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.
•
With the lower judgement function on, if set-
tings are made so that the test voltage divided
by the lower reference exceeds 1.1 mA,
“READY” disappears and “O
V
ER 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, “O
V
ER 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.
•
No lower judgement is made during the volt-
age rise time.
