4.7 Analyser Calibration
Note:
It is recommended to calibrate the analyser once a month.
Click on
Calibration
on the menu bar and then select
Calibration
to access the
CALIBRATION-CALIBRATION
menu (see Figure 39). This menu is used to calibrate the
system for the different gases being analysed.
The analyser must be properly started and purged before the execution of a
calibration. The calibration procedure consists of the Noise Threshold Calibration
followed by the Span Calibration.

4.7.1 Noise Threshold (THRSH) Calibration
This calibration step determines the noise level used for the peak detection
process.
No injection
will be made as this is a noise baseline on range #1. The
highest gain applied is always on this range. When starting the cycle, it will
automatically switch to range #1.
