A. Under insulation resistance measurement condition and without testing voltage
output, press to progressively decrease at the step of corresponding range
(decrease by 50% at a step of 10% each).
B. When setting time or resistance, button is used as a cursor button to adjust
time and resistance.
C. After polarization index or absorption ratio measurement is completed, press
to cyclically display polarization index or absorption ratio, insulation resistance in
Time2 and Time1.
A. Under insulation resistance measurement condition and without testing voltage
output, press to progressively increase at the step of corresponding range
(increase by 120% at a step of 10% each).
B. For time or resistance setting, button is used as a cursor button to adjust time
and resistance.
C. After polarization index or absorption ratio measurement is completed, press
to cyclically display polarization index or absorption ratio, insulation resistance in
Time2 and Time1.
READ
Without high voltage output, short press “READ” to read latest group of saved data,
and press
▲
and
▼
to select different data.
SAVE
Short press “SAVE” to save current displayed data. The LCD shows the symbol “FUL”
and the number of group “999” to indicate full storage. To save next group of data,
please clear the saved data.
Backlight button
Short press this button to turn on/off the backlight.
Setting confirmation button
For setting parameter in non-testing state, short press “ENTER” to confirm the setting
and exit the current setting.
Setting cancellation/exit button
For setting parameter without high voltage output, short press “ESC” to cancel current
setting and exit. Under “TIME” and “COMP” modes, short press “ESC” consecutively
for twice to return to the interface of continuous insulation resistance measurement.
Data deletion button
In “READ” state, short press “CLR” and then press “ENTER” to delete current data,
press “ESC” to exit data deletion function. In “READ” state, the symbol “CLR” and
the storage capacity symbol “2Hz” flash when “CLR” is long pressed for 2 to 3
seconds, press “ENTER” to confirm clearing all saved data, press “ESC” to exit data
deletion function. Note: To delete all saved data after short pressing “CLR”, please
long press “CLR” directly to enter after pressing exit button.
Data upload button
Short press this button to select USB data transfer mode, current transfer mode
can be displayed on the LCD synchronously , select current mode to transfer data
through confirmation button.
When connected to the computer software, press and hold this button to upload all
stored data to the PC.
USB: Active uploading for the tester.
Timer setting button
The default mode of the tester is continuous insulation resistance measurement
mode. Under insulation resistance measurement condition and without testing voltage
output, perform time setting for insulation resistance measurement mode.
Short press “TIME” to cyclically select “Continuous Measurement”, “Timer
Measurement”, “Polarization Index Measurement” and “Absorption Ratio
Measurement”, press “ENTER” to confirm the selection, press “ESC” to unselect
and return to default measurement mode.
Comparison measurement button
Under insulation resistance measurement condition and without testing voltage
output, short press “COMP” to select resistance comparison measurement as
insulation resistance measurement mode, the default comparison value is 10M
Ω
.
Measurement button
This button is used to turn on/off insulation resistance measurement or capacitance
measurement. Long press “TEST” for more than 2 seconds to start measurement.
If current measurement function is enabled, the red warning light illuminates the
background of “TEST” button. Short press “TEST” to exit measurement.
