Message field – battery status
Battery capacity indication.
Low battery.
Battery is too weak to guarantee correct result. Replace or
recharge the battery cells.
Recharging in progress (if power supply adapter is connected).
Message field – measurement warnings/messages
Warning! High voltage is applied to the test terminals.
Warning! Phase voltage on the PE terminal! Stop all the
measurements immediately and eliminate the fault before
proceeding with any activity!
Measurement is running. Consider any displayed warnings!
Measurement can be performed after pressing the TEST key.
Consider any displayed warning after starting the measurement!
Measurement prohibited. Consider any displayed warnings and
check online voltage/terminal monitor!
High electrical noise was detected during measurement. Results may
be impaired.
RCD tripped during the measurement. The trip limit may be exceeded
as a result of leakage current flowing to the PE protective
conductor or capacitive connection between L and PE conductors.
Instrument overheated. Temperature of internal components
in the instrument reached top limit. Measurement is prohibited
until the temperature is lower then that limit.
High resistance to earth of test probes. Results may be impaired.
(MI 3125E)
Fuse F1 is broken.
Result field
Measurement result is inside pre-set limits (PASS).
Measurement result is out of pre-set limits (FAIL).
Measurement is aborted. Consider displayed warnings and messages.
Sound warnings
Continuous
sound
Warning! Dangerous voltage on the PE terminal is detected.
