6.5.3. Anomalous situations
1. If the instrument fails to generate the nominal voltage, it
emits a long acoustic signal to indicate the negative result
of the test and displays a screen like the one at the side.

t the end of the test, if the measured resistance value is
lower than the set limit, the instrument emits a long
acoustic signal to indicate the negative result of the test
and displays a screen like the one at the side.

3. In AUTO mode, if the insulation measurement L-N is
<50k = 0.05M, all the tests are completed or if the
STOP key has been pressed, if RL-PE and RN-PE> Lim
and Vt> Vnom, the instrument shows a screen like the
one at the side. Disconnect the loads and resume the
test.
