Checking Reagent Pressure
Reagent supply system pressure must be between 8 and 18 psig (55.2 to
124.1 kPa) for proper operation. An internal pressure regulator/relief valve is
built in to ensure proper system pressurization. The system also includes a
pressure sensor. An analyzer system alarm actuates if reagent pressure is
outside of acceptable limits. Pressurize and check the reagent supply system
as follows:
1. Supply an external pressure source such as nitrogen or air between
20 and 60 psig.
2. Make sure the door to the reagent compartment is closed and turn the
reagent pressure interlock valve to the ON position.
3. Press the TEST key to call up the test menu:
