What to do if GE TransPort PT900 Measuring Instruments shows E4: Signal Quality error?
- S
  Sean AndersenJul 28, 2025
  If your GE Measuring Instruments displays an E4 error, it indicates that the peak of the upstream or downstream correlation signals has fallen below the programmed correlation peak limit, potentially due to a fluid, pipe, or electrical problem. To resolve this, check for sources of electrical interference. Verify the integrity of the tablet by temporarily using the PT900 on a test fluid/pipe that is known to be good. Also, inspect the transducers and relocate them if needed.

Why does my GE TransPort PT900 display E1: Low Signal?
- C
  Chad CollinsAug 1, 2025
  The E1 error on your GE Measuring Instruments indicates a low signal, which occurs when the SNR is less than the Signal Low Limit or the signal cannot be found. Check the components. Also, verify the programmed error limits value.

What to do if GE TransPort PT900 Measuring Instruments displays E3: Velocity Range error?
- A
  alexanderrebeccaAug 6, 2025
  If your GE Measuring Instruments shows an E3 error, it means there's an issue with the velocity range. This can be due to improper programming, poor flow conditions, or excessive turbulence. Ensure the actual flow rate is within the programmed limits and check the programmed Error Limits value. Correct any fluid, pipe, and transducer problems.

What causes GE Measuring Instruments to show E5: Amplitude Error?
- M
  msummersAug 21, 2025
  The E5 error, or Amplitude Error, on your GE Measuring Instruments can occur when solid or liquid particulates are present in the fluid or pipe, or due to poor couplant used on the clamp-on transducers. To address this, correct any fluid and pipe problems.
