Using the Features
Insulation Resistance Measurement Test Button (Yellow Button)
Press to apply the test voltage to the item to be tested. Release to terminate the test.
• While the yellow insulation resistance test button is pressed, the symbol will appear
on the display.
• See the Indicator Table for results of the insulation test.
Alarm
Press
ALARM
to turn the alarm on. Press again to turn the alarm off.
Note: Pressing the Test button activates the alarm if the meter is in continuity test mode. Press the
HOLD button to turn off the alarm while grounding.
Alarm Setpoints
1. Press and hold
ALARM
to review the setpoints.
2. Press
p
and
u
to change the setpoints. Press and hold
ALARM
to save the settings.

< 1 MΩ, < 2 MΩ, and < 4 MΩ
Note: The megohmmeter will correct any setting that is entered improperly.
Timed Insulation Resistance Test
Pressing the
TIMER
button activates timed test mode. This is only active for
insulation measurements.
1st Press: This locks the
TEST
button. When you press the
TEST
button, the unit will run without
requiring you to hold the
TEST
button down. The test will run for 15 minutes, or until you
press the
TEST
button again.
2nd Press: This activates timed test mode. You can set the test time with
u
and
p
to between 1 and
39:59 minutes. Use the
u
button to begin and move to the next digit. Use the
p
button to
change the digit.
3rd Press: This enables the
PI
function. This is used to calculate the polarization index (ratio of the
measurement at 10 minutes to the measurement at 1 minute.)
4th Press: Enables the
DAR
function. This is used to calculate dielectric absorption ratio (ratio of the
measurement at 1 minute to the measurement at 30 seconds.)
5th Press: Exit timed test mode.
