A flashing exclamation mark after the startup cycle on an Adixen ASM 142 indicates an issue, such as helium pollution or an automatic calibration failure.
To resolve an automatic calibration failure: 1. If the issue is helium pollution: - Keep pumping the analyzer cell for 10 minutes in standby mode. - Start an autocalibration. - If the problem persists, check for possible leaks or oil contamination.
2. If the failure is due to a peak locating error: - Check the calibration valve (VC3).
3. If the failure is related to an internal calibrated leak: - Inspect the internal calibrated leak for damage or lack of helium. - Verify consistency between internal and external calibrated leak measurements. - Replace the internal calibrated leak if necessary.
4. If the failure is caused by incorrect filament alignment: - Check and adjust the filament position.
5. If the failure is due to an analyzer cell issue: - Inspect the analyzer cell assembly.
Following these steps should resolve the automatic calibration failure.
