4.2.3 AC+DC voltage
60 mV range
: The measurement of high currents or over a long period can cause certain components to heat. In this case,
a certain waiting time is needed to return to the specified metrological conditions. It is possible to check whether the offset
has returned to an acceptable value by short-circuiting the + and COM terminals. A reading (R) of < 5 D should be obtained.
