Sensor programming
14. SENSOR PROGRAMMING
Since on ALMEMO
®
devices all sensor programming is stored in the ALMEMO
®
connector itself, the user will not normally need to reprogram each time. How-
ever, with humidity sensors it is necessary sometimes to program other humid-
ity ranges than those provided as standard.
Each channel can also be assigned a designa-
tion or smoothing.
In the
Sensor programming
menu these channel
parameters can (so long as the appropriate sen-
sor connector is plugged in) be entered, viewed,
checked, and modified via the keypad.
14.1 Measuring channel designation
Each measuring channel can be assigned a 10-character alphanumerical des-
ignation denoting as clearly as possible the type of sensor, measuring location,
and / or purpose. This designation is displayed in the functions menu. In out-
puts via the interface the measuring channel designation appears in the pro-
gram header as
Designation
.
To enter name in

Designation: Humid temp
14.2 Locking the sensor programming
The functional parameters for each measuring channel are protected by means
of the locking mode; this can be set to the desired locking level (see Manual,
6.3.12) Before programming you must lower the locking mode to an appropri-
ate level.

For the measuring channel M01 of a psychrometer (TT), the psychrometer
constant will be displayed instead of the locking function:
Function psychrometer constant:
Psychr.Const.:
0.000640
With D6 sensors the measuring channel is locked again automatically
at level 5 as soon as programming is finished.
14.3 Selecting a measuring range
If you want to change a measuring range you must first clear the locking mode
for the connectors concerned, i.e. set to 0. (see 14.2) To activate a new mea-
suring channel you must first activate all channels by pressing
<MALL>
