What to do if GE Measuring Instruments screen always reads the wettest value?
- A
  Anna MartinNov 23, 2025
  If your GE Measuring Instruments screen always reads the wettest programmed moisture calibration value while displaying dew/frost point, it could be due to: * Probe saturation: Liquid water may be present on the sensor surface or across electrical connections. Clean the sensor and sensor shield as described in document 916-064, Basic Hygrometry Principles, and then reinstall the sensor. * Shorted circuit: Run “dry gas” over the sensor surface. If the high reading persists, the probe is likely shorted and should be returned to the factory for evaluation. * Sensor contamination: Clean the sensor and sensor shield as described in document 916-064, Basic Hygrometry Principles, and then reinstall the sensor. * Improper cable connection: Check the cable connections to both the probe and...

What to do if my GE Measuring Instruments displays 'Over Range'?
- C
  Christine YangAug 27, 2025
  If the GE Measuring Instruments displays 'Over Range', it means that the input signal is above the calibrated range of the probe. You can change the measurement units so that the measurement is within range; for example, change ppb to ppm. If the measurement is not expected to be above scale, send the probe to BHGE for evaluation.

What to do if my GE Measuring Instruments displays 'Under Range'?
- M
  Melissa LiAug 27, 2025
  If the GE Measuring Instruments displays 'Under Range', it means the input signal is below the calibrated range of the probe. If the measurement is not expected to be below scale, send the probe to BHGE for evaluation.

Why is my GE Measuring Instruments showing a slow response?
- R
  Randy HoffmanAug 28, 2025
  If your GE Measuring Instruments is showing 'Slow response', it can be caused by: * Slow outgassing of the system: Replace the system components with stainless steel or electro-polished stainless steel. * Sensor contamination: Clean the sensor and the sensor shield as described in document 916-064, Basic Hygrometry Principles, and then reinstall the sensor.

Why is my GE moisture.IQ Analytical Instruments showing slow response?
- Y
  younggregorySep 15, 2025
  If your GE Analytical Instruments is responding slowly, it may be due to slow outgassing of the system or contamination of the sensor with non-conductive particles. You can replace the system components with stainless steel or electro-polished stainless steel. Additionally, clean the sensor and the sensor shield.

What does 'MIS NO LINK' mean on GE moisture.IQ Analytical Instruments?
- C
  Charles LaraSep 16, 2025
  If the GE Analytical Instruments displays 'MIS NO LINK', it means communication with a Moisture Image Series Probe has failed, indicating the probe is either disconnected or damaged. Check the Moisture Image Series Probe connections and replace the probe if necessary.

What to do if GE moisture.IQ Analytical Instruments screen always reads the wettest moisture calibration value?
- M
  michele48Sep 7, 2025
  If the GE Analytical Instruments screen always displays the wettest programmed moisture calibration value, it could be due to several reasons. There might be liquid water present on the sensor surface or across electrical connections, indicating the probe is saturated. Another possibility is a shorted circuit on the sensor. Conductive particles contaminating the sensor could also cause this issue, as well as an improper cable connection. You can clean the sensor and sensor shield. Also, check the cable connections to both the probe and the moisture.IQ. If the high reading persists after cleaning, the probe is probably shorted and should be returned to the factory for evaluation.
