9.3.10.1 Leak Check
CAUTION
When doing a leak check do not pressurize
the M200AU 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 8.7 for the leak check
procedure.
9.3.10.2 Sample Pump Diagnostic Procedures
The sample pump is capable of maintaining the reaction cell pressure at 3-4”Hg-A. If higher
pressures are noted, the pump may need servicing. Check the pump, inlet fittings, and analyzer
for leaks first. If other causes have been eliminated, rebuild the pump.
