9.3.10 Pneumatic System
The pneumatic system is diagramed in Figure 8-4, Figure 8-5, Figure 8-6, depending on which
options the instrument was ordered with.
9.3.10.1 Leak Check
CAUTION
When doing a leak check do not pressurize
the M200A to greater than 15psi.
Damage to internal components will
occur at higher pressures.
The basic cause of many performance problems is a leak. Refer to Section 8.9 for the leak check
procedure.
9.3.10.2 Pump
The external sample pump is capable of maintaining the cell pressure at 5"Hg-A. If higher
pressures are noted, the pump may need servicing. Check the pump/ozone scrubber for leaks or
rebuild pump.
The internal sample pump pressures tend to run slightly higher than the external pump due to its
smaller size. As in the case above, if higher pressures are noted the pump may need servicing. In
the internal pump configuration, the ozone scrubber is integrated into the molybdenum
converter.
