4.1 Perform a Calibration
OPERATION AT LOW TEMPERATURES
When operating an instrument at temperatures below 0 °C (32 °F), do
NOT apply gas nor operate the internal pump before the warmup time has
elapsed!
Violation may result in condensation inside the gas paths or damaged
pump diaphragm!
Before performing any actions, make sure the required calibration gas is applied
and owing!
Supply all calibration gases with the same ow and pressure as the sample gas
(recommended: approx. 1 l/min and maximum pressure 1500 hPa), and utilizing the
correct gas tting.
Ensure the warm-up time after switching on has elapsed!
Warm-up time depends on installed measuring system and conguration, mea-
surement specications in section 1.6!
Do NOT calibrate the TRACE MOISTURE sensor (tH
2
O)!
The sensor is completely calibrated with all calibration data stored in its ash memory
and does not require recalibration:
If the sensor is included into a calibration procedure, it might end up with a wrong cali-
bration and unusable sensor. Therefore the analyzer's trace moisture measurement
channel is congured to be excluded from autocalibration procedures, by default calibrat-
ing all channels. This exclusion is done by factory setup and cannot be changed.
For proper measurement results we recommend to exchange the sensor regularly
after 12 months of operation. For instructions on how to exchange, X-STREAM

Do NOT calibrate the TRACE OXYGEN sensor (tO

) without prior reading the
instructions!
Together with each sensor an installation manual is shipped, also giving comprehensive
calibration information.
Read these information prior intending to activate calibration procedures!
