Adjustment methods
Adjustment method
In an analyzer module (detector) one or more (gas) components with one or
more measuring ranges can be implemented.
For the adjustment of the analyzer module, it needs to be defined whether
the components and measuring ranges are to be adjusted jointly or individ-
ually. This definition takes place using the configuration of the adjustment
method.
Single adjustment
The analyzer module is adjusted individually for each measured component
in every measuring range at the zero point and at the end point.
The single adjustment has no effect on the other measuring ranges of the
same measured component and on the other measured component.
The single adjustment is only possible and practical for the manual adjust-
ment. The single adjustment is necessary if jumps in the display of meas-
ured value during the measuring range switching indicate that the adjust-
ments of the individual measuring ranges differ from one another.
Common adjustment
The analyzer module is adjusted in one measuring range each at the zero
point and at the end point for each measured component. The zero and end
points of the other measuring ranges are then corrected electronically by
the values established during this adjustment.
The common adjustment has no effect on the other measured components
of the analyzer module.
In general, the zero point is adjusted in the smallest measuring range and the
end point in that measuring range for which a suitable test gas is available.
Substitute gas adjustment
If the test gases for the adjustment are not available, e.g. because they can-
not be filled in test gas bottles or because their components are not com-
patible with one another, an analyzer module can be set at the plant for ad-
justing with a substitute gas in accordance with the order. In addition to the
measuring ranges of the measured components, one or more measuring
ranges are then set for the substitute gas component at the plant.
The analyzer module is adjusted in the measuring ranges of the substitute
gas and/or the measured components at a zero point and at an end point.
The zero and end points of the measuring ranges of all substitute gas and
measured components are then corrected electronically by the values estab-
lished during this adjustment.
NOTICE
In order to adjust all (measuring and substitute gas) components for analyz-
er modules that are set for adjustment with a substitute gas, the substitute
gas adjustment must be carried out at all times. A single or common ad-
justment either only in the measured components or in the substitute gas
measuring ranges results in an erroneous adjustment of the analyzer module.
