Rosemount 8712
When Should Signal Processing Be Used?
The Rosemount 8712 offers three separate functions that can be used in
series for improving a noisy output. The first step is to toggle the coil drive to
the 37 Hz mode and initialize with an auto zero. If the output is still noisy at
this stage, signal processing should be actuated and, if necessary, tuned to
match the specific application. Finally, if the signal is still too unstable, the
traditional damping function can be used.
NOTE
Failure to complete an Auto Zero will result in a small (<1%) error in the
output. While the output level will be offset by the error, the repeatability will
not be affected.
