Procedure: 

Item Comment 

 

Prepare test system. 

See 

chapter 4.3 Working 

with the adapter.

 

 

Connect power supply plug of tested appliance into 
proper test socket. 

 

Connect probe to accessible isolated conductive 
part of the appliance. 

See 

figure below.

 

 

Prepare and start measurement on the master 
instrument. 

 

 

Wait until measurement is finished or stop the 
measurement. 

 

 

Check result(s). 

 

 

Store result(s).
