To select a power-on option, press  and the function key simultaneously and 
then release the  button. Power-on options are retained when the tester is 
turned OFF. See Table 8.

Loop/Line Impedance I

K 

limit. Toggles the I

K

 limit between 10 kA 

and 50 kA. The default is 10 kA. 

  

Line and Neutral Swap mode. Two modes of operation are 
available. You can configure the tester to operate in L-n mode or 
L-n n-L mode, see Figure 7. 

•

  In L-n mode, the L and N phase conductors must NEVER be 

reversed. This is a requirement in some regions including the 
UK. The  icon appears on the display indicating that the 
system L and N conductors are swapped and testing is 
inhibited. Investigate and rectify the cause of this system fault 
before proceeding. L-n mode also changes the RCD x1/2 trip 
time duration to 2 seconds as required in the UK. 

•

  In L-n n-L mode, the unit allows the L and N phase conductors 

to be swapped and testing will continue. 

In locations where polarized plugs and outlets are used, a 
swapped lead icon () may indicate that the outlet was 
wired incorrectly. Correct this problem before proceeding 
with any testing. 

  

Fault voltage limit. Toggles the fault voltage between 25 V and 50 
V. The default is 50 V.

four digits and the secondary display shows the next four digits.
