O 2

Loop/Line Impedance I

limit. Toggles the I

limit between 10 kA

and 50 kA. The default is 10 kA.

O 3

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 6.

• 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 b 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.

Note

In locations where polarized plugs and outlets are used, a

swapped lead icon (b) may indicate that the outlet was

wired incorrectly. Correct this problem before proceeding

with any testing.

O 4

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

V. The default is 50 V.

O M

View the tester serial number. Primary display shows the initial

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

O A

Continuity beeper toggle. Toggles the continuity beeper on and

off. The default is on.
