TOS9200/9201 Basic Operations 3-23
Setting the upper current (UPPER)
• If the upper current is set to above 5 mA, the protective circuit may be acti-
vated. To avoid this, set the output time to 1 minute or less and provide a
pause longer than the test time.
The upper current can be set to 0.01 mA through 11.0 mA (at a resolution of 0.01
mA for the 0.01 mA to 9.99 mA range, and 0.1 mA for the 10.0 mA to 11.0 mA
range).
Once a current exceeding the upper current is detected, the test ends with a FAIL
judgement.
If the cursor is at the upper current, the rotary knob can be used to make settings.
1. If the upper current is not displayed, press the F3 key (UPPER) to dis-
play it (while 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.
• With the lower judgement function on, if the upper current is set at or below the
lower current, “READY” disappears and “UP<=LOW” fl ashes at the top right of
the LCD to indicate that testing cannot be performed (the lower current is factory-
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 55 W, “READY” disappears and “OVER 55 W” 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 the upper current.
