calibration set-up. The calibration tasks are set-up while operating in
Measure mode.
Notice the following:
1. Before starting to set-up a calibration task you must make sure
that you choose the correct FILTER BANK NO. to store the
calibration factors which will be calculated during calibration (see
section 12.3.3).
2. If you answer “YES” to PERFORM ZERO-POINT CALIBRATION
?, then the installed optical filters (“A”) will be zero-point
calibrated, and the concentration offset factor for the filter will
be stored in the filter bank no. which is active for that filter
during the practical calibration task.
3. If you answer “YES” to PERFORM HUM. INTERFERENCE
CALIBRATION ?, then the installed optical filters (“A”) will be
calibrated for humidity interference, and the humidity gain
factor for the filter will be stored in the filter bank no. which is
active for that filter during the practical calibration task.
4. If you answer “YES” to PERFORM GAS SPAN CALIBRATION ?,
then you can choose (1) whether this calibration should be a
single-point or a two-point span calibration. The concentration
conversion factor calculated during span calibration for a par-
ticular gas using a particular filter), is stored in the filter bank no.
which is active during the calibration procedure.
12.5.1 Retaining Existing Calibration Factors
In some case, you may wish to keep the calibration factors already
present in your monitor. If this is the case, use the following
instructions.
