Selecting Resistance Value-based or Current Value-based Judge-
ment
You can set the reference values for lower and upper judgement using resistance or
current values.
Judgement that uses the insulation resistance value is referred to as resistance value-
based judgement, and judgement that uses the value of the leakage current that
flows through the insulation resistance is referred to as current value-based judge-
ment.
You can switch between resistance value-based and current-value based judgment
using the SHIFT + F4 keys, regardless of the location of the cursor. Pressing
SHIFT+F4 causes the currently selected option to switch between resistance (R) and
current (I) and causes the units that are displayed on the screen to change.
Turning the timer ON/OFF
Make ON/OFF settings for the timer function.
When the timer function is turned on, the test time can be controlled as specified in
“Setting the test time” in the next section. When the preset test time has elapsed
with the resistance recorded between the lower and upper references, the test ends
with a PASS judgement.
You can be set the timer function to ON/OFF using the SHIFT + F5 keys, regardless
of the location of the cursor. Each time the SHIFT + F5 keys are pressed, ON and
OFF alternate.
The
keys can also be used to move the cursor to ON/OFF of the timer
function. If the cursor is at ON/OFF of the timer function, the rotary knob can be
used to make settings.
