12.3.2 Checking the Calibration of Each Installed Optical
Filter
A print-out of the calibration data in the Monitor’s memory is useful
to have for reference. It also enables you to find out how “old”
calibration factors compare with the “new” calibration factors
calculated during re-calibration tasks, see
illustrates only part of a typical calibration data print-out. To
simplify our discussion, we will confine our discussion to the
calibration data for a single optical filter installed in position “A”. Note
that there are five different filter banks, which contain calibration
data. These banks are numbered from 1 to 5. This enables each filter
to be calibrated to measure up to 5 different gases. Before the filter
is calibrated to measure any one particular gas, you have to inform
the Monitor about where you wish to store the calibration data for
this gas. The number of the filter bank chosen when operating in
Set-Up mode is called the active filter bank (see
).
When checking the optical filters using the front panel push-buttons,
provides details of how to obtain a print-out of calibration
data using a printer with an RS 232 interface.
Note that calibration data in the active filter bank is always printed
out directly after the optical filter factors data and this data is also
shown under the heading CALIBRATION DATA IN FILTER BANK
: X, where X is the number of the filter bank.
Note: all calibration factors are expressed as exponential numbers.
For example: 104.05E-3, this is the same as the number 104.05 x
10-3 = 0.10405
