Dear Sir,
we presume that the measuring chamber is polluted.
Please check and if necessary clean .

Question: Causes: Answer:

Zero adjustment reserve used up by 80 % <<<W 2>>>	The analyzer cell is contaminated. Drift response.	Clean the analyzer cell as described in Section 8.2.2.4. Readjust the IR source if necessary
Signal voltage < 30 % of full-scale value with sensitivity <<<W 3>>>	An incorrect calibration gas has been used. The detector is faulty. An incorrect measuring range has been selected for this calibration.	Check the calibration gas. adjustment Replace the detector . Select the appropriate measuring range.

Best regards
Tribute
