Operating Instructions
Primetest 220
11
During an insulation resistance measurement a
high voltage is applied between the Live/Neutral
and Earth of the EUT. It should be noted that
this voltage can also be present on the bare
metalwork of the EUT.
8.1.10The insulation resistance of the EUT is measured
over a period of 2 seconds. The large display 2
indicates digital insulation resistance, M
Ω , the
small display 3 indicates a PASS/FAIL status. An
additional visual display of a ✓ or a ✗ also indicates
PASS/FAIL status.
8.1.11The insulation resistance value will remain
displayed until another rotary switch action.
8.2 Protective Earth Conductor Current
See figure 4.
Attention - The Black 4mm test socket must not
be used whilst the PrimeTest 220 is performing
a leakage test. Electric Shock Danger.
Attention - before a protective earth conductor
current test is performed on a Class I EUT the
operator must ensure that the EUT has already
passed a Class I safety test.
Attention - An RCD may be triggered if the EUT
is defective.
Warning - it is important that the user verifies
that an appliance with moving parts (e.g. an
electric drill) is safely mounted to allow
movement without causing damage to
equipment or personnel.
8.2.1 Plug the supplied mains power lead into the mains
power socket 13 on the PrimeTest 220 .
8.2.2 Plug the other end of the supplied mains power
lead into a mains power socket.
