Why does auto calibration or single calibration fail on my RKI Instruments EAGLE 2?
- T
  Tyler BeckerAug 19, 2025
  If auto calibration or single calibration fails on your RKI Instruments Measuring Instruments, check the calibration tubing for leaks or bad connections. Ensure the instrument is properly set up for calibration. Verify the calibration cylinder has enough fresh test sample. The charcoal filter might be saturated, causing a high CO reading, so change it. If the problem persists, the sensor(s) may need replacement.
