NOTE 
z  When "Over" is displayed for Ohms, this signifies that a valid measurement was 
not obtained because either an open connection was detected or that the 
measurement was not within range. Readings greater than 9.999 Ohms will be 
displayed as Over.   
 
In Case of Failure 
Once it reaches the limitation, stop using and inform the Customer Service Engineer for 
analysis and disposal.

A.5 Earth Leakage Test 
Run an Earth Leakage test on the device being tested before performing any other leakage 
tests. 
 
Leakage current is measured the following ways:   
  Earth Leakage Current, leakage current measured through DUT outlet Earth   
  Earth Leakage Current AP-EARTH (ALL Applied Parts connected to Earth), leakage 
current measured through DUT outlet Earth   
There is no need to attach a test lead; the 601PRO automatically connects the measuring 
device internally.   
 
To Perform the Test 
1.  From the MAIN MENU, or with the outlet unpowered, plug the DUT into the 601PRO 
front panel outlet, and turn on the device.   
2.  Attach the device's applied parts to the 601PRO applied part terminals if applicable. 
3.  Press shortcut key 4.The Earth Leakage test appears on the display, and the test begins 
immediately:
