3. Perform a leak (pressure) check to ensure there are no leaks in the sys-
tem, then return to this procedure and complete the remaining start-
up and verification tests.
To perform the leak check, follow the procedure under “Sample Sys-
tem Leak Check,” later in this chapter.
4. After the leak check has been performed and has passed, close the
Bench Heater fuse and Oven Heater fuse (if Oven/Sample System
Enclosure is heated) to apply power to the Measuring Cell and Oven
Heater temperature-control zone circuitry.
No alarms will be displayed on the HOME screen or entered into the
Alarm Log until AFTER the system has left the Not Ready state
for the first time after power-up, which occurs after the entire sample
system has reached normal operating temperature and has stabilized
(2–3 hours).
5. While performing the remaining start-up tests, close the analyzer
doors to allow the sample system to warm up to normal operating
temperature (necessary only if Oven/Sample System Enclosure is
heated).
The Oven and the rest of the sample system will reach normal operat-
ing temperature (application-specific) in approximately 2 hours, but
may take up to another hour to stabilize.
To minimize the time it takes for the entire sample system to warm
up to normal operating temperature, be sure to close the doors after
performing the checks that require them to be open.
6. While working from the User Interface Panel, perform the following
checks to ensure the analyzer temperature-control zone circuitry is
operating properly and the system pressures are set appropriately.
Record the temperature value for each zone and the system pressures
to use as a reference later while comparing the values.
For instructions on working from the User Interface Panel, refer to
Chapter 4.
If changes need to be made to any of the parameters settings, a pass-
word must be entered to allow the changes to be made. For details
about entering a password, refer to “Login/Set Passwords Screen” in
Chapter 4.
