4.  Press and hold  until the reading settles. If the continuity beeper is 

enabled, the tester beeps continuously for measured values less than 2 

Ω

 

and there is no stable reading beep for measured values greater than 2 

Ω

. 

If a circuit is live, the test is inhibited and the AC voltage appears in the 
secondary (lower) display. 

In the Extended Documentation mode, the Tester stores the measurement 
result with the measurement location: R1+R2, R2, r1, r2 or rn. You can select 
the information before or after the measurement with . The definitions are: 
R1+R2 = Rx1/2, R2 = R/2, r1 = x1, r2 = /2, rn = x5.

Loop impedance is source impedance measured between Line (L) and 
Protective Earth (PE). You can also ascertain the Prospective Earth Fault 
Current (PEFC) that is the current that could potentially flow if the phase 
conductor is shorted to the protective earth conductor. The tester calculates the 
PEFC by dividing the measured mains voltage by the loop impedance. The 
loop impedance function applies a test current that flows to earth. If RCDs are 
present in the circuit, they may trip. To avoid tripping, always use the Zl No Trip 

function on the rotary switch. The no trip test applies a special test that 
prevents RCDs in the system from tripping. If you are certain no RCDs are in 
the circuit, you can use the Zl Hi Current function for a faster test.
