Data logger functions
Please note that alarm displays will increase current consumption
and, depending on the operating period, shorten the battery’s useful
life. To acknowledge - and thus terminate - alarm display when in
sleep mode press the
ON
key. The acoustic alarm signal will end
automatically after 10 seconds.
11.2.5 Date and time-of-day
For logging the measuring time a real-time
clock with date and time-of-day is incorpor-
ated. This real-time clock is buffered by the
power supply to the device; in the event of bat-
tery replacement date and time-of-day are
lost. Having selected the date and time-of-day
functions via key
FCT
information is entered

After a battery change these func-
tions are automatically activated and
unlocked for the purpose of entering
information.
