9. Warning and status messages
9.1 Loop test inhibit or premature termination of a loop test:
A loop test may stop or even be prevented from starting if there is a connection problem with the test leads or
instrument fuse, an earth problem on the circuit being tested, or a supply voltage or frequency out of range.
Test inhibit
If an out of range voltage or frequency exists on the circuit under test, testing will be automatically inhibited and
the corresponding information will be displayed.
The following ‘Exceptions’ and ‘Warning’ screens may be displayed during testing:
UNSERVICEABLE - Instrument needs to be returned for repair.
Circuit voltage may also be displayed.
Test aborted due to excessive noise present during test. Retest or
investigate source of noise.
Instrument needs calibration. Further testing is possible but not recommended.
Noise symbol [
] displayed at end of test indicates result may have been
adversely affected by electrical noise during test. Test should be repeated.
Instrument overheated. Allow to cool down.
Hot warning. Thermometer symbol [
] flashes. Allow instrument to cool
down, but testing can continue if necessary.
Supply interrupted or lost during test (eg test probe slipped). This will
disappear after 2 seconds and the tester will attempt to repeat the test.
Ready to test No-trip loop test. No supply voltage connected.
Ready to test using High Current loop test. No supply voltage connected.
‘TEST IN PROGRESS’
messages.
Supply voltage missing or low.
UNSERVICEABLE - Fuse failed.
Circuit voltage may also be displayed.
Touch voltage limited measurement to 1000
Ω
. Check earth bonding of
installation before further testing.
