Device Configuration
10.5.7 Hysteresis
In case of an exceeding of limit values the hysteresis of an alarm condition
can, generally for all sensors, be set in the function
Hysteresis
(s. 10.3.5
and manual 6.2.7) within the range from 0 to 99 digits (standard setting is 10
digits).
Change hysteresis (0 to 99) s. 8.5:
Hysteresis: 10
10.5.8 Operating Parameters
Some operating parameters are software options and can be user-configured
with the function
Configuration
(s. manual 6.10.13.2).
Mains frequency noise suppression 60Hz instead of 50Hz
Configuration: F-------
Clearing all measured values on start of a measurement
Configuration: -C------
Ring memory (overwriting of old data when full)
Configuration: --R-----
Switching off the signal transmitter
Configuration: -----S--
The following parameters can be used to check the device function:
Out of 20 channels 5 are activated:

CJ-Temperature: 25.4°C
10.6 Output Modules
The data logger ALMEMO
®
2690-8 has two
output sockets, A1 and A2, to allow an output
of the measured values as analog or digital
values or as alarm signals. Furthermore, it is
possible to trigger various functions through
trigger pulses. To suit all possibilities, while
keeping the hardware requirements at a mini-
mum, all necessary interfaces have been in-
tegrated into the ALMEMO
®
output con-
nectors.
The output modules, like the sensors, are
automatically detected and displayed in the
menu
OUTPUT MODULES
so that, generally,
no programming is required.
The various connection possibilities are only
listed here, but they are concretely described
in the manual section 5.
