3.6.1.1. Pneumatic Setup for the T400 Analyzer with Zero/Span Valve Option
For a Model T400 photometric ozone analyzer with the optional zero/span valves, attach
the following pneumatic lines:
SAMPLE GAS SOURCE:
Attach a sample inlet line to the SAMPLE inlet fitting.
Sample Gas pressure must equal ambient atmospheric pressure (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:
At least 0.2m long
No more than 2m long
Vented outside the shelter or immediate area surrounding the instrument
CALIBRATION GAS SOURCES:
SPAN GAS
Attach a gas line from the source of calibration gas (e.g. a Teledyne API T700 Dynamic
Dilution Calibrator) to the SPAN inlet.
Span gas can by generated by a M700E Mass Flow Calibrator equipped with a
Photometer Option or an M703E UV Photometric Ozone Calibrator.
