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!
Do NOT calibrate the TRACE OXYGEN sensor (tO
instructions!
Together with each sensor an installation manual is shipped, also giving comprehensive
calibration information.
Read these information prior intending to activate calibration procedures!
Do NOT calibrate the TRACE MOISTURE sensor (tH
The sensor is completely calibrated with all calibration data stored in its flash 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 configured 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,

Before performing any actions, make sure the required calibration gas is applied
and flowing!
Supply all calibration gases with the same flow and pressure as the sample gas
(recommended: approx. 1 l/min and maximum pressure 1500 hPa), and utilizing the
correct gas fitting.
Ensure the warm-up time after switching on has elapsed!
Warm-up time depends on installed measuring system and configuration,
