What does U-Sonic Failure Mean on a Sigma 950?
What a U-Sonic Failure means on a Sigma 950.
- When the Black Bar at the bottom of the Display Screen or in the event log shows U Sonic Failure, there is no signal from the Ultra Sonic Transducer to the meter.
- Main causes for this is are: transducer is not connected, cut or broken cables, change in temperature, inability to read new calibrated level, or a bad sensor.
- To troubleshoot, check cabling for kinks or cuts. Make sure the transducer is plugged in. Make sure the temperatures at the motoring point are not fluctuating. Recalibrate the unit.
