Turning the upper judgement function ON/OFF
The upper judgement function can be turned on/off.
When the lower judgement function is on, the test ends with a FAIL judgement if
the measured insulation resistance or the value of the leakage current that flows
through the insulation resistance drops below the lower reference.
The upper reference is explained in the following section. You can set the upper
judgement function to ON/OFF using the SHIFT + F3 keys, regardless of the loca-
tion of the cursor. Each time the SHIFT + F3 keys are pressed, ON and OFF alter-
nate.
The
keys can be used to move the cursor to ON/OFF of the upper judge-
ment function. If the cursor is at ON/OFF of the upper judgement function, 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 functions are off, no FAIL judgement is made.
Note that, when the timer is turned on with both functions off, a PASS judgement
is made.
