5.4.2. Ambient Zero/Ambient Span Valve

This valve option is intended for applications where zero air is supplied by a zero air generator like a bottle of N2 and span gas are being supplied by Gas Dilution Calibrator like the Teledyne Instruments Model 700 or 702. Internal zero/span and sample/cal valves control the flow of gas through the instrument, but because the calibrator limits the flow of span gas no shutoff valve is required.

In order to ensure that span gas does not migrate backwards through the vent line and alter the concentration of the span gas, a gas line not less than 2 meters in length should be attached to the vent span outlet on the rear panel of the analyzer. To prevent the buildup of back pressure, this vent line should not be greater than 10 meters in length.

The following table describes the state of each valve during the analyzer’s various operational modes.
