3.3 Switch On/Off, Data Storage, Reinitialisation
The ON/OFF switch (1) on the left side of the device has three positions:
up: ON
down: OFF
For switch-on the slide switch (1) on the left side must be moved upwards.
The device is switched off when the slide switch s moved to the lower position.
Data Storage
When the instrument is switched off the real time clock continues its operation
and the stored data is maintained as long as the available voltage of the 9V
battery is above 6V. When changing the battery the residual voltage is sufficient
for at least one minute. If the new battery is connected within that period no
data will be lost. Otherwise, a reinitialisation must be performed.
Reinitialisation
If the battery supply has been interrupted or if the device is not functioning
properly due to disturbances (e.g. electrostatic charging or wrong connection of
peripherals) or if incorrect programming must be avoided, the instrument can
be reinitialised.
The reset can be achieved if the key
CLEAR
is pressed during switch-on. During
this process the measuring data, time and date, as well as all internal data such
as cycles, conversion rate, atmospheric pressure and function key assignment,
will be deleted or set to their default values. However, the device configuration
and the sensor programming within the ALMEMO
®
connectors will not be
affected by the reset.
