Commentaire - Cause possible
Voltage > U between the TEST key and PE: the measurement
L
is disabled.
One of the voltages, U or U is < 90 V : the measurement
LN LPE
is impossible.
U is AC and > U : the measurement is impossible.
NPE L
The frequency of U , U , or U
LN LPE
65 Hz : the measurement is impossible.
The rod is not connected, the measurement is stopped.
U > U : the measurement is disabled.
P L
Resistance of the auxiliary rod too high: the measurement
is stopped.
Connection of a current probe after selection of measurement
without tripping: the instrument automatically reverts to
measurement with tripping and reports the fact.
During the measurement, U exceeds the value set in the
F
SET-UP mode: the measurement is stopped.
During a selective measurement, the product of the current
measured by the current probe and the measured voltage is
too low: the measurement is stopped.
During a selective measurement, the current measured by the
current probe is too unstable: the measurement is stopped.
The temperature of the instrument is too high: the masurement
is stopped. Pressing the TEST key has no effect until the
temperature of the instrument is again below 60°C; another
measurement can then be started.
