What to do if MEDISTIM Medical Equipment Flow/Doppler Probe is not detected?
- P
  Paul JacksonAug 14, 2025
  If the Flow/Doppler Probe isn't detected, or Pressure/Aux signals aren't recognized, or you see a 'probe failed' message with 0% ACI, first ensure the probe connector is fully inserted into the port. Next, inspect the connector for broken or bent pins. If the problem persists, try the probe in another port of the same type. If it still fails, dispose of the probe and replace it with a new one.
