4.4 Perform a Calibration
Before performing any actions, make sure the required calibration gas is applied
and fl owing!
Supply all calibration gases with the same fl ow and pressure as the sample gas (re-
commended: approx. 1 l/min), and utilizing
the correct gas fi tting.
Ensure the warm-up time after switching on has elapsed! Warm-up time depends on
installed measuring system and confi guration, „1.8 Measurements Specifi cations“
at page 1-14!
Do NOT calibrate the TRACE MOISTURE sensor!
The sensor is completely calibrated with all calibration data stored in its fl ash memory
and does not require recalibration:
If the sensor is included into a calibration procedure, it might end up with a wrong ca-
libration and unusable sensor. Therefore the analyzer's trace moisture measurement
channel has to be excluded from any autocalibration procedures! You have to care for
not calibrating the trace moisture sensor each time a calibration is performed!
For proper measurement results we recommend to exchange the sensor regularly
after 12 months of operation. For instructions on how to exchange,

X2 instruction manual
Do NOT calibrate the TRACE OXYGEN sensor without prior reading the instruc-
tions!
Together with each sensor an installation manual is shipped, also giving comprehensive
calibration information.
Read these information prior intending to activate calibration procedures!
OPERATION AT LOW TEMPERATURES
When operating an instrument at temperatures below 0 °C (32 °F), do NOT
apply gas nor operate an internal pump before the warmup time has elapsed!
Violation may result in condensation inside the gas paths or damaged pump
diaphragm!
