| Symptom | Possible causes | Solution |
| All channels in a module go to zero | high voltage is getting to at least one channel on that module | Check valves for shorts turn off all stamp boxes. Turn half back on to determine which half is causing the problem. Note that it can take a minute for the module to recover or to fail again when the high voltage is reapplied |
| All channels in a module go out of range | lack of grounding for power supply | Verify that the ground cable from the data acquisition cables is attached to the power supply box. |
| Unresponsive sensor | voltage range is set too high | Set voltage range to match Sensor output |
| Sensor output out of range | Voltage range is set to low | Set voltage range to match Sensor output |
| Sensor is shorted | If sensor electronics got wet, allow it to dry | |
| Sensors using the same power supply get noisy and go out of range intermittently | Power supply is failing | Replace power supply |

Noisy - Several of the data acquisition channels of the data acquisition board were found to be noisy when attached to capacitance-based wave gages. It is possible that the noise was caused by the cable connecting the SCXI 1000 mainframe to the black Ethernet breakout box.
