SAFETY WARNINGS
Safety Warnings and Precautions must be read and understood before the instrument is
used. They must be observed during use.
Continuity of protective conductors and earthed equipotential bonding of new or modified
installations must be verified before carrying out an earth fault loop impedance test, or RCD
test.
Do not leave the instrument connected to the mains supply and switched to a loop
impedance range when a loop impedance test is not being performed.
Circuit connections and exposed metalwork of an installation or equipment under test must
not be touched.
Do not move the rotary selector switch position while a test is in progress.
The LCD 'neon' voltage indicators cannot reveal a Neutral-Earth reversal.
The instrument should not be used if any part of it is damaged.
Test leads, probes and crocodile clips must be in good order, clean and with no broken or
cracked insulation.
NOTE
THE INSTRUMENTS MUST ONLY BE USED BY SUITABLY TRAINED AND COMPETENT PERSONS.
