Setting the upper current (UPPER)
The upper 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 the cursor is at the upper resistance, the rotary knob can be used to make set-
tings.
1.
To display the upper resistance, press the F3 key (UPPER). (When the
upper 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 upper resistance.
• With both the upper and lower judgement functions on, if the upper resistance is
set at or below the lower resistance, “READY” disappears and “UP<=LOW”
fl
ashes at the top right of the LCD to indicate that testing cannot be performed.
(The upper resistance is factory-set to 100 M
Ω
.)
Raise the upper resistance, reduce the lower resistance, or turn off the lower
judgement function.
• With the upper judgement function on, if settings are made so that the test voltage
divided by the upper 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 upper resistance.
