Do not remove the test lead immediately. Wait until the discharge 

is complete before touching the circuit under test.  

In order to ensure the measurement accuracy, do not twist the 

test lines together.

Insulation  resistance  test  can  only  be  carried  out  on  an  uncharged 

circuit. Before testing, check that the test leads are good and confirm that 

the circuit under test is uncharged. 

Turn the rotary switch to 

gear, then press 

VSEL

 to select the voltage 

value to be tested. 

One  end  of  the  ground  wire  (black)  is  connected  to  the  instrument 

connection 

EARTH

 and the other end is connected to the ground end of the 

circuit under  test. One end of the  high-voltage rod  test line  (red)  is 

connected to the other end of the instrument 

LINE

 and the head is in contact 

with the circuit under test.If the test has a green branch line as a shielded 

line, the accuracy of connecting the GUARD port during testing is better. 

If the matching test line does not carry this line, it does not need to be 

connected. As shown in the figure, press the 

TFRT

 test button. The LCD shows
