Refer to Figure 2-3 while performing this procedure.
1. Crack open the sample inlet valve allowing a low volume
purge of the sample system.
2. Very slowly open the inlet value allowing it to reach process
pressure.
3. Begin closing the filter/coalescer outlet needle valve and the
sample outlet valve until both valves are nearly closed.
4. Adjust the sample outlet needle valve and the filter/coalescer
outlet valve until you feel a slight pressure against your finger
at the venting tubes.
5. Open the inlet valve fully. Be sure the flow out of the venting
tubes remains the same as in step 4. To prevent physical
damage, do not subject the probe to excessive flow.
6. Turn on the PM880.
