None Do not perform any verification checks for mean.
3 Stdev (default) If the difference between baseline mean value and the verification
value exceeds 3 standard deviations, diagnostic will stay in Verification
mode.
6 Stdev If the difference between baseline mean value and the verification
value exceeds 6 standard deviations, diagnostic will stay in Verification
mode.
2% If the difference between baseline mean value and the verification
value exceeds 2%, diagnostic will stay in Verification mode.
The Detection Configuration screen (Figure 7-11 and Figure 7-12) allows for
configuration of sensitivity threshold values for tripping the diagnostic and
how to receive the HART alert or analog alarm.
