Operating instructions ULTRAMAT 23 gas analyzer
C79000-B5276-C216-03
Using this function it is possible to calibrate the IR channels of the
ULTRAMAT 23 using one or more calibration gases, and to reset the
sensitivity. In addition, you can calibrate the oxygen sensor and the
pressure sensor and also define the AUTOCAL parameters. Fig. 5-5
shows the associated menu sequence (see Section 5.7 for description
of display elements).
Calibration is only possible if you have enabled code level 1.
In this menu you can:
S
Set, in line 2, the setpoints of the calibration gases for the individual
ranges or select a total or single calibration.
S
Start a calibration procedure in lines 3 and 4.
This function is specific to the component.
S
Total cal.: In the first line of this dialog, you can select either a total
or single calibration.
ON means that one range is calibrated and that this calibration is
used for the other ranges (total calibration).
OFF means that each range is calibrated separately (single
calibration, e.g. with different calibration gases).
S
With AUTOCAL: You can define here whether you wish to carry out
an AUTOCAL prior to the calibration procedure (YES or NO). An
AUTOCAL is not necessary here if it has already been carried out
shortly before the calibration procedure, e.g. a calibration procedure
has taken place directly previously.
S
Span1, Span2: Here you can enter the setpoints for the individual
measuring ranges (these are the concentrations of the components
in the respective calibration gas). They should be set to a value
which is between 70 and 100 % of the full-scale value. If Total cal.:
ON has been selected, the analyzer automatically uses the setpoint
of range 2 for range 1. With Total cal.: OFF any input is possible
between the start-of-scale and full-scale values of the respective
range.
