Chapter 2 Precautions on Handling 

This chapter  describes the precautions  to  be  followed  in the  handling  of  this tester.  When  using the 

tester, take utmost care to ensure safety. 

                                                                                                                                                         

 

         

 

！

  WARNING:  The  tester  derives  a  5  KVAC  or  6KVDC  test  high  voltage,  incorrect  or  wrong 

operation can cause accidents which will result in human injury or death. When operating the tester, 

be extremely careful and observe the cautions, warnings, and other instructions given in this chapter, 

keep them in mind to avoid accidents. 

                                                                                                                                                                         

2.1

 

Operation Standards 

1)

 

Wearing Insulation Gloves 

When  handling  the  tester,  be  sure  to  wear  insulation  gloves  in  order  to  protect  yourself  against 

high voltages, even though, please do not touch the live conductor by hand when high voltage test 

is conducting.

 

2)

 

Grounding 

There  is  a  protective  grounding  terminal  on  the  rear  panel  of  the  tester  chassis, 

please  use  a  dedicated  tool  to  connect  it  to  an  electrical  ground  (safety  ground, 

earth). If there is no good grounding, when the circuit of the power is shorted to 
the ground or any device’s power line is shorted to the ground, the tester chassis is 
charged to an excessively high voltage, resulting in extreme danger, anyone who 

touches such tester chassis, will result in electric shock accident, therefore, please 

make  sure  that  the  protective  grounding  terminal  is  connected  to  the  safety 

ground.

 

3)

 

Test Line Connection 

Press

【

STOP

】

first,  confirm  that  DANGER  lamp  is  not  lit,  then  connect  the  test  line.  When 

connecting the test lead wire to a DUT, please connect the DUT with the test lead wire of HV2 

or  RTN/LOW  first.  It  is  very  dangerous  if  the  test  line  connection  of  HV2  or  RTN/Low  is 

incomplete or dropped, because the entire DUT will be charged with high voltage.   

After high voltage plug of the high voltage test lead is inserted into HV1 and HV2, it must be 

rotated 90 degrees clockwise to prevent the test lead wire from falling off. 

Before testing, it is a must to check whether the test lead wire of HV1 and HV2 or RTN/LOW are 

connected, loose or fall off. 

4)

 

Stop (Pause) Test 

       

To change the test conditions, please press the STOP once first, this will take the tester out of 

the test preparation state and ensure that the DANGER lamp is off. If need to take a break or 

leave the test location, please switch off the power, to prevent the accidental contact with the 

start switch and cause a safety hazard. 

5)

 

Remote Control 

Be  very  careful  when operating  the  tester  in  remote  control  mode,  because  the start and  stop  of 

Safe ground
