Alarm Set Point Adjustments
Numerical Adjustment Versus Adjustment by Observation
An alarm set point is established using either numerical adjustment or adjustment by observation. The adjustment by observation requires
the customer to establish normal process operation and adjust the alarm set point relative to this condition. The numerical approach requires
measuring normal and alarm process conditions with a voltmeter and setting up the instrument in the calibrate mode based on these values.
The adjustment by observation requires less time to establish the alarm set point. The numerical adjustment requires control of the process
as well as additional time to establish the alarm set point. Use the adjustment procedure that is the most appropriate for the application
requirement.
