Key Functions
Table 7. Key Description
ON/OFF
Turn on or off the Meter. Press and hold the button for 1 second to turn the
Meter on.
LIGHT
Turn on and off the display backlight
CLEAR
Press to clear the stored data
SAVE
Press to store the current measurement value. The maximum number of
stored reading is 18. When the stored readings memory is full, the Meter
shows FULL and stop storing. Press
CLEAR
to clear the stored value in order
to store the next measurement value.
LOAD
l
Press once to recall the first stored value.
l
Press again to exit Load feature.
l
Load feature can only be used when there is no high voltage output.
Ʒ
l
Under insulation resistance measurement mode: press to select one
voltage range up.
l
Under load mode: press to recall the previous stored value.
ͩ
l
Under insulation resistance measurement mode: press to select one
voltage range down.
l
Under load mode: press to recall the next stored value.
l
When set the timer duration for the measurement of insulation resistance
or polarization index, press to decrement the time. The maximum
length of time is 30 minutes, the Meter will automatically carry out
measurement.
l
When compare feature measuring insulation resistance, press to
decrement a resistance comparing value.
l
After polarization index measurement, press to display polarization index,
TIME 2 insulation resistance value and TIME 1 insulation resistance
value in sequence.
l
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 30 minutes, the Meter will automatically carry out
measurement.
l
When use the compare feature measuring insulation resistance, press to
increment a resistance comparing value.
l
After polarization index measurement, press to display polarization index,
TIME 2 insulation resistance value and TIME 1 insulation resistance
value in sequence.
STEP
Press to display S1->S2-S3 in sequence.
l
When the Meter is under timed measurement or polarization index
measurement:
Ø
S1 means increment of 1, then each press of
increase 1 or
decrease 1.
Ø
S2 means increment of 10, then each press of
increase 10 or
decrease 10.
Ø
S3 means increment of 30, then each press of
increase 30 or
