3.4 Performance functions
The next five main menu functions help to tailor the
magmeter signals to your specific environment.
3.4.1 Sensitivity
The sensitivity function limits the amount of refer-
ence level noise detected by the Magmeter input
circuit. Use the StdE display (sec 3.5.2) to
evaluate the amount of reference noise in your
system. If StdE is greater than 0.05, decreasing
the sensitivity value may stabilize flow readings.
The range selections are from 1 to 10, with 1
representing the most sensitive and 10 the least
sensitive.
To change the sensitivity setting, first enter the
access code (section 3.2.1) then press the down
arrow until the display shows:
