- the instrument checks the connections : if incorrect, the measurement is refused and the
faulty connection symbols flash.
- if an AC or DC voltage > 42 Vrms is detected, the measurement is stopped,
During the measurement,
- in manual mode only, the

key is used to change the polarity of the measurement
current.
Note : if the measurement is unstable or if the measurement results are inconsistent, trigger
the measurement again to check that the problem is not a faulty connection.
On completion of the measurement, the following quantities can be displayed using
