General Operation
4.1
Automatic Settings, Monitoring and Shutdown
The instrument cannot be placed into operation, or it is shut down
automatically, if battery voltage has fallen to below the lower limit value.
Measurement is automatically interrupted and/or the measuring function
is disabled if voltage exceeds the allowable limit in the resistance range
(U > 25 V).
The instrument switches itself off automatically, at the earliest after the
current (automatic) measuring sequence has been completed, and after
the predefined on-time has elapsed (see chapter 3.3). On-time is reset to
the duration selected in the setup menu each time a key is activated.

The selected function
When automatic measuring sequences are used, the measurement
values are displayed in digital format until the next measuring sequence is
started, or until the instrument switches itself off automatically.
If the measuring range upper value is exceeded, the upper value is dis-
played preceded by the greater than symbol “>” in order to indicate over-
ranging (If the actual value is less than the measuring range lower value,
the value is displayed preceded by the less than symbol “<”, e.g. with
10 V or 100 V test voltage).
