3-8 Basic Operations TOS9200/9201
Setting the upper current (UPPER)
• If the upper current is set above 50 mA, the protective circuit may be acti-
vated. To avoid this, set the output time to 30 minutes or less and provide a
pause longer than the output time.
The upper current can be set between 0.01 mA and 110 mA (at a resolution of 0.01
mA for the 0.01 mA to 9.99 mA range, 0.1 mA for the 10.0 mA to 99.9 mA range,
and 1 mA for the 100 mA to 110 mA range).
When a current exceeding the upper current is detected, the test ends with a FAIL
judgement.
When the cursor is at the upper current, the rotary knob can be used to make set-
tings.
1. To display the upper current, press the F3 key (UPPER). (When the
upper current 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 current.
• If the upper current is set at or below the lower current while the lower judgement
function is on, “READY” disappears and “UP<=LOW” fl ashes at the top right of
the LCD to indicate that testing cannot be performed. (The upper current is fac-
tory-set to 0.20 mA.)
Lower the lower current, raise the upper current, or turn off the lower judgement
function.
• When settings are being made, if the test voltage multiplied by the upper current
exceeds 550 VA, “READY” disappears and “OVER 550 VA” fl ashes at the top
right of the LCD to indicate that testing cannot be performed.
In such a case, reduce the test voltage or the upper current.
