5.3 Start-up
Preparation
Before start-up, there are two tasks to perform:
Install or replace the circular chart as described in 55H5.16 56HRoutine Maintenance.
Be sure that the configured settings for the current time and wake time (time at which recording begins)
are correct. Note that the recorder is “awake” during start-up to verify interaction with the process.
During start-up, you should verify the interaction between your process and the DR4500A recorder to be
sure that your process can tolerate some upsets during this procedure.
Diagnostic tests
When power is applied, the recorder will run four diagnostic tests. 57HTable 5-3 lists the four diagnostic tests.
