12. Reverse L-N Polarity (not available on all instruments)
In countries where the power plug can be reversed in the socket (example: Schuko) the earth leakage tests can be configured to test in
normal “forward” polarity or “normal and reversed” polarity.
Checking the “Reverse L-N Polarity” box in the “Add User”, “Edit User” or “Expert Options” screen enables the forward and reverse
earth leakage testing.
Reversing the test is performed automatically and the worse of the two results are recorded.
The display will show the L
→
N and N
→
L symbols during the leakage tests when this mode is enabled.
