If this is not detected the unit will display a flashing

If the earth resistance meas
ured is greater than
the selected PASS limit for
earth bond (0.1Ω/0.2Ω/0.3Ω), the meter will display “×Earth Cont”, which is a
FAIL. If this occurs, re-check the connections between the pin of the plug to the
bodywork of the appliance and that the crocodile clip is attached to clean earthed
metalwork on the appliance (try attaching the clip to an alternative piece of
metalwork). If all connections are OK the appliance earth connection may be
faulty.
The PASS limit for the earth bond test can be set to 0.1Ω, 0.2Ω or 0.3Ω for a
Class 1 appliance. (See page 17.)
If the reading is less than the selected PASS limit, the meter will display “√ Earth
Cont”, which is a PASS.
The unit will then automatically attempt to proceed to the insulation test. If it
detects that the appliance’s power switch is in the ON position it will carry out the
insulation test automatically.
