MI 3152(H) EurotestXC (2,5 kV) Instrument operation
28
Instrument is overheated. The measurement is prohibited until the
temperature decreases under the allowed limit.
High electrical noise was detected during measurement. Results may be
impaired.
Indication of noise voltage above 5 V between H and E terminals during earth
resistance measurement.
L and N are changed.
In most instrument profiles L and N test terminals are reversed automatically
according to detected voltages on input terminal. In instrument profiles for
countries where the position of phase and neutral connector is defined the
selected feature is not working.
Warning! High voltage is applied to the test terminals.
The instrument automatically discharge tested object after finished insulation
measurement.
When an insulation resistance measurement has been performed on a
capacitive object, automatic discharge may not be done immediately! The
warning symbol and the actual voltage are displayed during discharge until
voltage drops below 30 V.
Warning! Dangerous voltage on the PE terminal! Stop the activity
immediately and eliminate the fault / connection problem before proceeding
with any activity!
Continuous sound warning and yellow coloured screen is also present.
Test leads resistance in R low / Continuity measurement is not compensated.
Test leads resistance in R low / Continuity measurement is compensated.
High resistance to earth of current test probes. Results may be impaired.
High resistance to earth of potential test probes. Results may be impaired.
High resistance to earth of potential and current test probes. Results may be
impaired.
Too small current for declared accuracy. Results may be impaired. Check in
Current Clamp Settings if sensitivity of current clamp can be increased.
In Earth 2 Clamp measurement results are very accurate for resistances
below 10 Ω. At higher values (several 10 Ω) the test current drops to few mA.
The measuring accuracy for small currents and immunity against noise
currents must be considered!
Measured signal is out of range (clipped). Results are impaired.
Single fault condition in IT system. (MI 3152 only)
