      Christopher McdanielAug 20, 2025
      If your Gemu Measuring Instruments display a 'Programming error stroke < min. stroke', consider these possible causes and solutions: 1. Minimum stroke not reached: Ensure the minimum stroke is reached (possibly due to a stroke limiter) and then re-programme. 2. Shut off diaphragm compressed too much (diaphragm size 8): Ensure correct compression of the shut off diaphragm and then re-programme.

    How to resolve programming error after sensor error in Gemu 1235 Measuring Instruments?
    • N
      Nancy TurnerAug 25, 2025
      If you encounter a programming error after a sensor error with your Gemu Measuring Instruments, it means that the sensor range was exceeded during the programming procedure, but the process valve is now within the valid sensor range. To resolve this, check the mounting kit and re-programme. Make sure to note the maximum stroke as specified in the "Technical data".
