The following table gives some examples of some typical
Linear Scale values for common accelerometer sensitivities.:
Obtaining a readout in units other
than “g”.
If the desired linear units are different from those provided
by the manufacturer, m/s
2
for example, calculate the
sensitivity in those units, Volt/m/s
2
, and use that value in the
equation for Linear Scale.
Setup of Linear Units Readout.
The items to be defined to implement this feature are
“Linear Units” and “Linear Scale” which appear in the FFT
Edit Settings menu as shown in “Settings Menu” on page
12-1 and on the screen as shown below.
