Commissioning
6.4 Commissioning
ULTRAMAT 23
82 Manual, 3/2016, A5E37100388-003
Once all preparatory work for commissioning has been completed, go through the following
checklist:
● The analyzer is set to the correct operating voltage
● All gas preparation elements are connected and ready for operation, and have been
checked for leaks
● All required connections to and from the analyzer have been established
Following successful checking, connect the analyzer to the power supply and switch it on.
Wait for the warm-up phase to elapse (see Warm-up phase (Page 95)).
The analyzer carries out an automatic calibration with the connected medium during the
warm-up phase following switching-on. This AUTOCAL adjusts the zero point and sensitivity
of the IR channels. If an O
2
sensor is present, its sensitivity is additionally calibrated using
the ambient air (20.95% O
2
).
Note
Analyzers with H
2
S sensor
The hydrogen sulfide sensor is not
calibrated during the course of this first AUTOCAL. The
2
S sensor is only calibrated starting from the second AUTOCAL of the
Note
Analyzers without electrochemical O
2
sensor
In the case of analyzers without an electrochemical O
2
sensor, the AUTOCAL can be
carried
out with nitrogen, but in the case of analyzers with an electrochemical O
2
sensor, it is
essential to use air. The correct medium is selected depending on the used configuration
(gas connections) and cannot be parameterized using the software.
Note
Analyzers with paramagnetic O
2
sensor
In the case of analyzers with a paramagnetic O
2
sensor, the input menu can be used to
select whether the AUTOCAL is to be carried out with air or N
2
, and thus whether the
2
) or the zero point of the sensor is calibrated.
