6.5 Switching ON / OFF, reinitialization

To switch ON press key(s) :
block. The measuring menu most recently selected always appears first in the
display.
To switch OFF press and hold down the same key(s)
vice is switched off the real-time clock continues to run and all saved values
data and settings are retained intact; (see 6.6).
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

Reset press
tings will be lost. To restore all device programming (including device designa-
tion, user menus, process control, etc.) to the factory default settings press
when switching on. In so doing many parameters will be lost or be restored to
their defaults : Language = German, Illumination = off, Device address = 00,
Atmospheric pressure = 1013 mbar, Temperature compensation = 25°C, Hys-
teresis =10, Measuring rate = 2.5 mops semi-continuous. Only the program-

6.6 Data buffering

The sensor's programming is stored in the EEPROM on the sensor connector;
the internal data memory and the device's calibration and programmed param-
eters are stored in the EEPROM on the instrument itself, all on a fail-safe ba-
sis. Date and time-of-day settings and the individual values memory are re-
tained intact if the device is just switched off but are lost when the device is re-
set or the batteries are replaced.

strument. To connect your own existing sensors you simply need the appropri-

ALMEMO range of sensors (see Manual Ch 3) and instructions for connecting
your own existing sensors to ALMEMO
standard sensors with an ALMEMO
range and units already programmed and can thus be connected to any input
socket without further adjustment. A mechanical coding system ensures that
sensors and output modules can only be connected to the correct sockets. All
®
ALMEMO connectors incorporate two snap-lock levers; these snap into posi-
tion as soon as the connector is inserted into the socket, thus preventing unin-
