Autocalibration
Autocal has been programmed using functions
40 ff.
The LED “autocal” flashes during the automatic
calibration.
The calibration is repeated at an interval defined
in function 42.
Factory setting: 0
An autom atic calibration (zero, calib ration
gas(es)) is triggered. The autocalibration cycle
is not influenced by this.
The cyclic repetition of the calibration procedure
is defined here. If a time setting which has alrea-
dy been imported is modified, the new time only
becomes effective following the next autocal.
This time can be defined using function 41.
Factory setting: 168
