Waiting period following automatic adjustment
If the Output Current Response parameter is set to Hold, current output is
halted for a specific time to allow the measured value to stabilize after au-
tomatic adjustment is ended.
This waiting period is
Purging time test gas → measurement gas + 4 x T90 or
Purging time test gas → measurement gas + 1 x T90-1 + 3 x T90-2.
When different T90 times are specified for several sample components the
largest T90 time is used for all sample components.
Adjustment data
The setting of the adjustment data is described in the sections "Configuring
automatic adjustment of the FID" (see page 86) and "Configuring automatic
adjustment of the oxygen sensor" (see page 88). The setting of the T90 time
constants is described in section "Configuring filter" (see page 108).
