Activation
Automatic calibration is only performed when activated.
The "off" setting applies only to the interval-controlled start of automatic
calibration.
Cycle time
The cycle time shows the time intervals over which automatic calibration is
to be carried out.
Date and time of next calibration
The gas analyzer will perform the next automatic calibration at the time
established here. The cycle time starts from this point of time.
Operating mode
Automatic calibration is based on the function block Autocalibration. This
function block operates either as calibration or as validation (see page 230).
The Technical Information "Function Blocks – Descriptions and configura-
tion" contains complete information on the individual function blocks.
Test gas concentration for the calibration
The zero and span test gas concentrations to be used as set points for au-
tomatic calibration need to be set for the selected sample component and
measurement range.
If the Limas11 IR, Limas21 UV, Limas21 HW or Uras26 analyzer module is
equipped with calibration cells the test gas concentration does not have to
be set.
Components for calibration
The sample components to be calibrated during zero and span calibration
need to be selected.
