Calibration Methods
Calibration Method An analyzer module (detector) can have one or more (gas) components with one
or more measurement ranges each.
To calibrate the analyzer module, establish whether the components and ranges
should be calibrated jointly or individually. This decision is based on the
calibration method configuration.
Single Calibration The analyzer module start and span values for each measurement range are
calibrated individually for each sample component.
Single calibration has no effect on other measurement ranges for the same
sample components and on other sample components.
Single calibration is only possible and practical in the manual calibration mode.
Single calibration is required if there are skips in the readings during measurement
range switches because these indicate differences in the calibrations of the
individual measurement ranges.
Note: Skips in readings during measurement range switches do not occur in the
Uras26, Limas11 and Magnos206 since these analyzer modules have only one
physical measurement range.
Common Calibration Only the analyzer module start- and end-points in one measurement range are
calibrated for each sample component. The start- and end-points of the other
measurement ranges are then corrected electronically on the basis of the values
established by this calibration.
A common calibration has no effect on the other sample components in the
analyzer module.
In general the start-point (zero) is calibrated in the smallest measurement range
and the end-point (span) is calibrated in the measurement range for which a
suitable test gas is available.
Substitute Gas
Calibration
If test gases are not available for calibration, e.g. because test gas containers can-
not be filled with them or because of incompatibilities between their components,
an analyzer module can be set to substitute gas calibration. In this case, in addi-
tion to the sample component measurement ranges, one or more ranges are set
up at the factory for substitute gas components.
One start-point and one end-point are calibrated in the analyzer module’s substi-
tute gas measurement ranges. The start- and end-points of all substitute gas and
sample gas measurement ranges are then corrected electronically on the basis of
the values established by the substitute gas calibration.
Substitute gas calibration must always be used to calibrate all (sample gas and
substitute gas) components for analyzer modules set up for substitute gas calibra-
tion. Single or common calibration either in the sample component or substitute
gas measurement ranges leads to erroneous analyzer module calibration.
