Alarm Setpoint Adjustments
Numerical Adjustment Versus Adjustment by Observation
An alarm setpoint 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 setpoint relative to this condition. The numerical approach requires mea-
suring 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 setpoint. The numerical adjustment requires control of the process as well
as additional time to establish the alarm setpoint. Use the adjustment procedure that is the most appropriate for the application requirement.
