Startup Tasks
On start-up, when primary AC power is applied to the analyzer, the analyzer first processes
whatever electronic self-tests and diagnostics are required such as PROM, RAM, A/D, and
communication ports. This processing occurs within 5 seconds.
System-related initial messages are generated and output to the network ports. Appropriate
initial messages are then displayed on the Maintenance Panel and completed within 20 to 25
seconds. If the analyzer cycle clock is in RUN or CAL mode, an appropriate alarm may be
generated during this internal test and the following startup period.
