FAQ:
Question: What are the possible causes of the message "Calibration difference too great"?
Answer:
1. Calibration gas was changed: Recent replacement of calibration gas may introduce discrepancies if the new gas has a different concentration or composition compared to the original.
2. Drift behavior due to contaminated gas lines: Contaminants (e.g., oil, moisture, or debris) in the gas lines can interfere with gas flow, leading to unstable readings or persistent drift.
Question: Which Siemens FIDAMAT 6 models are compatible with this keypad membrane switch?
Answer: The 7MB2421-0BA10-0AA1 and 7MB2421-0DA10-1AA1 keypad membrane switches are specifically designed for Siemens FIDAMAT 6 gas analyzers, ensuring perfect compatibility and seamless integration into existing systems.
