Insulation resistance measurement
1. Connect the red test wire and black test wire to reciprocal
terminal socket.
2. Setting the function switch to proper position according
to the content of insulation material, (you can take a try
follow the sequence 500V/ 1000V/ 2500V/5000V if you
do not know the resistance range) for example, 2500V:
