- C
  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.
