Teledyne 9110T instruction manual 13.3.12, Calibration GAS Sources

Model 9110T NOx Analyzer Getting Started

∙Sample Gas pressure must equal ambient atmospheric pressure (no greater than 1.0 psig).

∙In applications where the sample gas is received from a pressurized manifold, a vent must be placed on the sample gas line. This vent line must be no more than 10 meters long.

CALIBRATION GAS SOURCES

SPAN GAS Attach a gas line from the source of calibration gas (e.g. a Teledyne M700E Dynamic Dilution Calibrator) to the SPAN1 inlet (see Figure 3-20). Use PTFE tubing; minimum O.D ¼”.

ZERO AIR Zero air is supplied by the zero air generator such as a Teledyne M701. Attach a gas line from the source of zero air to the ZERO AIR inlet.

VENTING

In order to prevent back diffusion and pressure effects, both the span gas and zero air supply lines should be:

∙Vented outside the enclosure.

∙Not less than 2 meters in length.

∙Not greater than 10 meters in length.

EXHAUST OUTLET

Attach an exhaust line to the EXHAUST OUTLET fitting. The exhaust line should be:

∙	¼” PTFE tubing
∙ maximum 10 meters long
∙ Vented outside the 9110T analyzer’s enclosure
Note	Once the appropriate pneumatic connections have been made, check all
	pneumatic fittings for leaks using the procedures defined in Section
	13.3.12.

To find instructions on calibrating a 9110T with this option installed, see section 10.4.
