8. ZERO CHECKS AND RE-CALIBRATION
During normal operation of the analyzer the following checks may be requested as required:
• Zero setting of all sensors (can also be selected manually)
8.1 ZERO SETTING
The zero setting function sets the working sensors to zero using fresh air. This function is activated as
