ON OFF r
. After the device is switched off all saved values and settings are re-
tained intact; (see 7.4).
If interference (e.g. electrostatic) or a malfunction (e.g. battery failure) causes
the device to behave abnormally, the device can be reinitialized. To activate
RE-
SET press and hold down the key CLR r when switching on. This will restore all
settings to the factory default status. Only the programming of the sensors in
the ALMEMO
® connectors remains unaffected.

Data buffering
The sensor's programming is stored in the EEPROM on the sensor connector
and the device's calibration and programmed parameters are stored in the
EEPROM on the instrument itself, both on a fail-safe basis.

CONNECTING THE TRANSDUCERS
Only certain ALMEMO® sensors can be connected to ALMEMO® input socket
M0 (1), namely those programmed with measuring ranges as per Ch 10.1.2.
Attempting to connect any other sensor here will trigger an error message. To
connect your own existing sensors you simply need the appropriate ALMEMO®
connector.
8.1
Transducers
The ALMEMO® Manual includes detailed descriptions of the ALMEMO® range
of sensors (see Manual Ch 3) and instructions for connecting your own existing
sensors to ALMEMO® instruments (see Manual Ch 4). All suitable sensors with
an ALMEMO® connector (see above) have the measuring range and units al-
ready programmed and can thus be connected to the input socket without fur-
ther adjustment. A mechanical coding system ensures that sensors and output
modules can only be connected to the correct sockets. All ALMEMO® connect-
ors incorporate two snap-lock levers; these snap into position as soon as the
connector is inserted into the socket, thus preventing unintended disconnection
if the cable is accidentally pulled. To withdraw the connector, both these levers
must be pressed in at the sides.
For the ALMEMO® 2450-1L version with the optional seal new specially de-
signed sensors are available with spray-coated ALMEMO® connectors incorpo-
rating a double sealing lip to protect the socket unit against the effects of splash-
ing water. For any unused sockets protective stoppers are available.
