7.4 MiniC unit troubleshooting
CAUTION The miniC measuring sensor can only be repaired and calibrated at the
factory. In case of failure, the complete miniC unit should be sent to GE
Healthcare for factory exchange.

Explanation
The sample tube inside or outside the monitor is blocked or water
trap is occluded. If occlusion persists, measured gas values
disappear.
Occlusion over 40 seconds.
- The water trap is not connected
- There is a leak in the sampling line inside the module. If air leak
persists, measured gas values disappear.
Check sample gas out.
Air leak over 40 seconds.
Indicates residue build-up on the water trap membrane. This
decreases air flow.
Entering calibration is not allowed during 5 minutes after power up
and during occlusion or air leak.
- Gas out connector on the front panel, or the exhaust line
connected to it, is blocked.
- If the sample gas is returned to the patient circuit, the filter in the
return kit may be occluded.
- Make sure the sample gas outlet is connected to an open
scavenging system only where gas is removed in room pressure.
Time out, fluctuating gases, gain adjusted "over".
Unsuccessful zeroing.
Unsuccessful calibration.
Unsuccessful zeroing.
Calibration gas accepted and monitor is ready for adjusting the gas
values to match the calibration gas concentration.
Unsuccessful calibration.
