Teledyne 9110T instruction manual Setup for Calibration Using Valve Options

Model 9110TH NOx Analyzer Calibration Procedures

9.4.MANUAL CALIBRATION AND CAL CHECKS WITH THE VALVE OPTIONS INSTALLED

There are a variety of valve options available on the 9110T for handling calibration gases (see Section 1.4 for descriptions of each).

Generally performing calibration checks and zero/span point calibrations on analyzers with these options installed is similar to the methods discussed in the previous sections. The primary differences are:

∙On instruments with Z/S valve options, zero air and span gas is supplied to the analyzer through other gas inlets besides the sample gas inlet.

∙The zero and span calibration operations are initiated directly and independently with dedicated buttons (CALZ & CALS).

9.4.1.SETUP FOR CALIBRATION USING VALVE OPTIONS

Each of the various calibration valve options requires a different pneumatic setup that is dependent on the exact nature and number of valves present. Refer to the following diagrams for information on each or these valve sets.
