CAUTION
Even though the test current in the 2000 ohm range (15mA test
current) is low some RCD's may trip due to sensitivity or where
there may already be additional leakage in the circuit being tested.
The Loop impedance in a TN system is small and therefore it is
not recommended to test in the 2000 ohm range. RCD's will have
to be bridged to avoid tripping when using other test ranges.
