Calibrations and bump tests can fail if there is not enough gas reaching the sensors. To ensure that gas is flowing from the gas cylinder to G7 Dock, check that:

• There are no kinks or crimps in the tubing.

• The gauge on the gas cylinder indicates there is gas inside (i.e., check that the gas cylinder is not empty).

• The gas cylinder is using a demand-flow regulator.

• The quick-connects are properly connected to G7 Dock.

• Gas concentrations in the gas cylinder match Dock configurations.

If G7 Dock is still not operating correctly, please contact Technical Support.
