ACF5000 FTIR ANALYZER SYSTEM | OI/ACF5000-EN REV. A 155
Basic adjustment
NOTICE
The adjustment reset is only possible with the analyzer modules FID and
oxygen sensor.
What does the basic adjustment do?
A basic adjustment of an analyzer module sets the module back in an initial
state. The offset drift and amplification drift are set to zero. The drift history
is lost.
When should a basic adjustment be performed?
The basic adjustment of an analyzer module should only be carried out if
changes were made to the analyzer module that influence the adjustment.
This can, for instance, be the case when replacing assemblies.
Check prior to a basic adjustment
Prior to a basic adjustment, check and ensure
That the analyzer system is in proper operating condition
That the sample conditioning units are in proper operating condition
That the correct test gases are being used.
Test gases
The zero and/or span adjustment test gases are required for a basic ad-
justment.
Carrying out the basic adjustment
The basic adjustment is carried out for a measured component.
The basic adjustment can be carried out
Individually at the zero point
Individually at the end point, as well as
Together (successively) at the zero and end points.
An adjustment reset (see page 154) is also performed in the case of common
basic adjustment at the zero and end points.
