Standard Specifications
Earth Voltage Check (IR4082 only)
Specifications Chapter 3
Functions
Insulation Resistance measurement:
DC voltage supply, current detection
AC Voltage measurement:
Average responding type
AC resistance measurement (IR4082 only)
Measurement principle, constant AC supply, volt-
age detection (synchronous detection), effective
resistance value indication (can be used in earth
resistance measurement by bipolar method)
Live circuit indica-
tor
When 20 VAC or higher exists between LINE termi-
nal and EARTH terminal or 20 VDC or higher exists
during automatic discharge, the red LED lights up.
Automatic electric
discharge
Automatically discharges the electric charge still
present in the capacitance of the test object.
Auto Power Save
The power will only go off automatically 15 minutes
after the last live circuit alert has been displayed.
Indicator
Meter (Internal magnet type taut band method)
Light device: LED
Light goes off about 3 minutes after MEASURE key
is switched to OFF or when LIGHT key is pressed.
