Note on voltage
display in IR test
mode
In Insulation Resistance test mode, this device is used to check whether or not the
electric charge stored in the equipment under test has been discharged. During an
Insulation Resistance test, the voltage value displayed on the LCD above the
resistance measurement is the test reference voltage value.
* NOTE: For 5000V IR measurements, use of the ac adapter to power the unit is recommended.
