17.6 Clock/Battery
The supply voltage supplies the internal clock of
the meter. If the supply voltage fails, the battery
takes over the supply of voltage to the clock. The
clock provides date and time information, for ex-
ample, for recordings, minimum/maximum values
and events.
The life expectancy of the battery is at least 5
years at a storage temperature of +45 °C (113 °F).
The typical life expectancy of the battery is 8 to 10
years.
