Why does the Anatel A-1000 Analyser keep indicating 'testing'?
Anatel A-1000 only showing 'testing'
If an A-1000 only shows "testing" and cycling power does not help, pull the battery and do a full reset. Also make sure that the boards are fully seated inside. If this does not help, contact Hach Service and provide the serial number to send the analyser in to bench service for repair.
