
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.

SPAN GAS
Attach a gas line from the source of calibration gas (e.g. a Teledyne
API's T700 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 API's
M701. Attach a gas line from the source of zero air to the
ZERO AIR
inlet.
V
ENTING
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
E
XHAUST
O
UTLET
Attach an exhaust line to the EXHAUST OUTLET fitting. The exhaust line should be:

¼” PTFE tubing

maximum 10 meters long

vented outside the T200 analyzer’s enclosure
Note Once the appropriate pneumatic connections have been made, check all
pneumatic fittings for leaks using the procedures defined in Section 11.3.12.
For instructions on calibrating a T200 with this option installed, see Sections
9.2.3.2 and 9.4.
