Insulation resistance testing
3
a .Connection of measuring lead
Insert the plug of lead with big probe to “L” socket.
Insert the plug of lead with big clip to “E” socket
The lead with the big measuring clip is connected with the
earth. The lead with big probe is connected to measuring object.
The lead insert in “G” socket is the shield lead to leak current of
testing resistance,connected to ground.
b.DC test voltage select
Select the DC voltage which the insulation resistance you want
to test.
Turn the rotating switch to the needed voltage .
c.Testing
Turn on the power by lightly pressing the button
(TEST/STOP).The power is turned on when the button is
pressed, Press the button once again to turn the power off.
When the power is turned on, measuring high voltage is
generated, measurement is started, and LED on the panel will
light. the value will be showed on the LCD. This is the value of
insulation resistance measured.
If the high voltage indicator LED on the panel is lighting at this
time, it means that the tester is working correctly and correct
voltage has been impressed on the measuring object. This LED
does not light when the batteries have been exhausted or the
contact of batteries is not proper.
d.Finish
Press the button (TEST/STOP) once more after
themeasurement completed. When the red LED off, means the
output testing high voltage has been over. Turn the rotary switch
to “OFF” position. If the load contains capacitance, please short
the testing object first to discharge residually electricity before
move the testing leads.
