Always clean the gas lines and verify there are no leaks at the connections after a gas cylinder is
connected. This test examines the gas line from the analyzer to the gas cylinder, then from the
analyzer to the regulator shut-off valve. A report is generated at the completion of the test to verify
that it has passed or failed.
Always confirm the state for valves and the low-pressure gauge reading.
