L-PE loop measurement. This is a way of making a high current, 2-wire 
loop measurement. It cannot be used on circuits protected by RCDs 
because it will cause them to trip. 

•

 

Prospective Short Circuit Current (PSC). PSC is the current that can 
potentially flow if the phase conductor is shorted to the neutral conductor or 
another phase conductor. The tester calculates the PSC current by dividing 
the measured mains voltage by the line impedance.

1.  Turn the rotary switch to the

 

 

position. The LCD indicates that the 

high current loop mode is selected by displaying the  symbol. 

2.  Connect the red lead to the L (red) and the blue lead to the N (blue) 

terminals of the tester. 

3. Press 

 to select L-N. 

4. Press 

 to select between  and m resolution for the test results. 

The m resolution test takes between 30 and 60 seconds to 
complete. 

5.  Use the zero adapter to zero the test leads or the mains cord. 
6.  Press and hold  for more than two seconds until the ZERO 

annunciator appears. 
The tester measures the lead resistance, stores the reading in 
memory, and subtracts it from readings. The resistance value is saved 
even when the power is turned off so it is unnecessary to repeat the 
operation each time you use the tester with the same test leads or 
mains cord.
