Diagnostics
Diagnostics are provided to assure ongoing performance of the Analyzer PRO instrument. Upon each
connection to the instrument, Self-Test is performed automatically. The instrument monitors itself,
and will alert the operator in the event of malfunction.
It is wise to institute ongoing testing to monitor instrument performance and operation. The
frequency for this testing depends upon application and usage, and should be set by the System
