Seaward 220 PrimeTest - Manual (Page 24)

Operating Instructions
Primetest 220
During an insulation resistance measurement a
high voltage is applied between the Live/Neutral
of the EUT and the black test probe. It should be
noted that this voltage can also be present on
bare metalwork of the EUT.
8.5.6 The insulation resistance of the EUT is measured
over a period of 2 seconds. The large display 2
indicates a digital insulation M
Ω , the small display
3 indicates a PASS/FAIL status. An additional
visual display of a ✓ or ✗ also indicates PASS/FAIL
status.
8.5.7 Insulation resistance value is held on the LCD
display for a period of 1 second. The displayed
insulation resistance will flash if a FAIL and remain
steady if a PASS.
8.5.8 The result will remain displayed until another rotary
switch or pushbutton action.
8.6 Touch Leakage Current,
See figure 8
Attention - before a touch leakage current test
is performed on a Class II EUT the operator
must ensure that the EUT has already passed a
Class II 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.
8.6.1 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.
