Do not change functions on the test instrument with the test leads in place, i.e. changing from a “dead test”
to a test where the supply is required could damage the instrument.
This instrument has been tested according to the below regulations:
EN 61326: Electrical equipment for measurement, control and laboratory use.
EN 61010-1: Safety requirements for electrical equipment for measurement, control and laboratory use
–Part 1: General requirements.
BS EN61557: Electrical safety in low voltage distribution systems up to 1000V a.c. and 1500V d.c.
Equipment for testing, measuring or monitoring of protective measures.
Part 1 General requirements
Part 2 Insulation resistance
Part 3 Loop resistance
Part 4 Resistance of earth connection and equipotential bonding
Part 6 Residual current devices (RCDs) in TT and TN systems
Part 7 Phase sequence
Part 10 Combined measuring equipment
Various error conditions are detected by the tester and are indicated with the icon, Err, and an error
number on the primary display. See Table 1. These error conditions disable testing and, if necessary, stop
a running test.

Solution
Check the installation, in particular, the voltage
between N and PE.
Wait while the tester cools down.
Switch off all appliances (Loop, RCD measurements)
and move the earth stakes (earth measurement).
Put the stakes deeper into the soil. Tamp down the
soil directly around the stakes. Pour water around
the stakes but not at the earth ground under test.
Return the tester to a Service Center.
