3-34 Basic Operations TOS9200/9201
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.
The keys can be used to move the cursor to ON/OFF of the lower judge-
ment function. When the cursor is located at ON/OFF of the lower judgement func-
tion, the rotary knob can be used to make settings.
Turn the rotary knob clockwise : ON
Turn the rotary knob counterclockwise : OFF
• If the lower and upper judgement function is off, no FAIL judgement is
made for that function. Note that a PASS judgement is made when the
timer is turned on.
Setting the lower current (LOWER)
The lower resistance can be set to 0.01 M Ω through 9.99 G Ω (at a resolution of 0.01
M
Ω
for the 0.01-9.99 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 maximum rated current.
When a resistance value at or below the lower resistance is detected following a wait
time, the test ends with a FAIL judgement.
When the cursor is at the lower resistance, the rotary knob can be used to make set-
tings.
1. To display the lower resistance, press the F2 key (LOWER). (When the
lower resistance is displayed, the cursor can be moved using the
keys.)
2. Using the keys, move the cursor to the target digit.
3. Using the rotary knob, set the lower resistance.
• With both the upper and lower judgement functions on, if the lower resistance is
set at or above the upper resistance, “READY” disappears and “UP<=LOW”
fl ashes at the top right of the LCD to indicate that testing cannot be performed.
(The lower resistance is factory-set to 1.00 M
Ω
.)
Reduce the lower resistance or raise the upper resistance.
• With the lower judgement function on, if settings are made so that the test voltage
divided by the lower resistance exceeds 1.1 mA, “READY” disappears and
