OPERATION

Key Functions

Turn on or off the Meter. Press and hold the button for 1 second to turn the Meter on. Press
again to turn off the Meter.
ON/OFF
The Meter default range is 500V insulation resistance continuous measurement when turning
on.
Emergency stop button. Press this button when the Meter's operating system crashed and can
E-STOP
not stop measurement.
Press to turn on or off the display backlight
CLEAR /
Press and hold to clear the stored data
Press to store the current measurement value. The maximum number of stored reading is 18.
SAVE When the stored readings memory is full, the Meter shows FULL and stop storing. Press and

value.
• Press once to recall the first stored value.
LOAD • Press again to exit Load feature.
• Load feature can only be used when there is no high voltage output.
• When the insulation resistance measurement has no testing voltage output, press to select
one voltage range up.
• Under load mode: press to recall the previous stored value.
• When the insulation resistance measurement has no testing voltage output, press to select
one voltage range down.
• Under load mode: press to recall the next stored value.
• When set the timer duration for the measurement of insulation resistance or polarization
index, press to decrease the time. The maximum length of time is 15 minutes, the Meter will
automatically carry out measurement.
• When compare feature measuring insulation resistance, press to decrease a resistance
comparing value.
• After polarization index measurement, press to display polarization index, TIME 2 insulation
resistance value and TIME 1 insulation resistance value in sequence.
• When set the timer duration for the measurement of insulation resistance or polarization
index, press to increment the time. The maximum length of time is 15 minutes, the Meter
will automatically carry out measurement.
• When use the compare feature measuring insulation resistance, press to increase a
resistance comparing value.
• After polarization index measurement, press to display polarization index, TIME 2 insulation
resistance value and TIME 1 insulation resistance value in sequence.
• Press once to start the data transferring to the computer via USB, USB symbol shows on the
display.
