Why is there no output current from the current loop?
Check the M55 window to ensure the required current‑output mode is selected and not set to “closed current loop”.
Why does the meter show zero instantaneous flow even though fluid is present?
If a static zero point was set while fluid was flowing, clear it using the M42/M43 settings to restore the original zero point.
