What does tamper alarm mean on a Honeywell Transmitter?
- F
  Fred BartonSep 7, 2025
  If the Honeywell Transmitter is in Write Protect Mode and Tamper Mode is enabled, or the Tamper Alarm alone is enabled, and outside attempts to change device configuration exceeded the set Tamper limit, identify the source of tampering. If configuration changes are required, contact a qualified individual to unlock the Write Protection Mode feature and disable the Tamper Mode and make the required updates.

Why is my Honeywell Transmitter showing PV out of range?
- R
  Raymond MillerAug 23, 2025
  If the Honeywell Transmitter displays 'PV Out of Range', it might be due to a sensor overload or fault, a redundant characterization calculation error, or the calculated pressure exceeding the Upper Transducer Limit (UTL). Check the range and, if necessary, replace the transmitter with one that has a wider range. The meter body may be damaged, so check the transmitter for accuracy and linearity. Replace the Meter Body and recalibrate if needed.

What does loop current noise mean on a Honeywell Transmitter?
- B
  Bruce RamirezAug 27, 2025
  If you observe loop current noise frequently on your Honeywell Transmitter, it could indicate an impending critical under or over-current failure. Closely monitor the device for other failure signs, or proactively replace the electronics module.

What causes a sensor fault in Honeywell ST 800?
- F
  fromeroAug 27, 2025
  If the Honeywell Transmitter shows 'Sensor Fault', it could be due to a failure on the sensor board, a redundant characterization calculation error, or the calculated pressure exceeding the Upper Transducer Limit (UTL). Check the range and, if required, replace the transmitter with one that has a wider range. The meter body may have been damaged. Check the transmitter for accuracy and linearity. Replace the Meter Body and recalibrate if needed.

What does sensor overload mean for Honeywell ST 800 Transmitter?
- G
  Gary GoldenAug 29, 2025
  If your Honeywell Transmitter indicates 'Sensor Overload', it means the calculated pressure is above the Upper Transducer Limit (UTL). Check the range and, if required, replace the transmitter with one that has a wider range. The meter body may have been damaged. Check the transmitter for accuracy and linearity. Replace Meter Body and recalibrate if needed.

What to do if Honeywell ST 800 reports no DAC compensation?
- H
  Heather LeonSep 6, 2025
  If the Honeywell Transmitter displays 'No DAC Compensation', replace the Electronics Module (PWA) to achieve the maximum current loop accuracy or return the device to factory for DAC compensation. Note that loop accuracy may be slightly compromised, resulting in a minor degradation of ambient temperature influence specifications.

What does 'No Factory Calibration' mean on a Honeywell ST 800 Transmitter?
- S
  Steven OconnorSep 3, 2025
  If the Honeywell Transmitter is showing 'No Factory Calibration', it means the factory calibration is missing, which will compromise accuracy. Replace the meter body or return the device for factory calibration.
