7.0 OPERATION
Too get rid of such situation, you should enter a new (lower) threshold value. To enter a new
value just use the numerical keys on the keypad followed by enter key (E key). The value must
be between 0 and 16,777,215 counts. The default value is normally just what the system needs
and under normal conditions this value should not be changed.

Minimum: 0 counts
Maximum: 16 777 215 counts
Resolution: 1 count
This value is set by Servomex, and may need to be re-adjusted over the year.
7.6.2 Temperature Coefficient
This menu gives the possibility to enter coefficient that will be used for system temperature
variation. Using these factors, the software will do a temperature compensation to minimize
temperature drift. There are two factors, one for the offset and another for the gain. The
temperature affects the baseline of the instrument and the sensitivity. These factors are entered at
the factory during temperature drift tests. Don’t change them, except if you suspect that they are
not good. There is a procedure to follow to do temperature tests. If you have to do it, call
Servomex to get the exact procedure. It must be done by trained personnel. Most of the time
there is no compensation and these factors are then set to 1.000.
Press F1 to access the temperature offset menu.
