AC Filter
AC filter applies to ACV and ACI measurements. It can optimize the low-
frequency accuracy and minimize the AC settling time. T3DMM6-5 provides
three types of AC filters (>3Hz, >20Hz, >200Hz).
The AC filter to be used is determined by the input signal frequency. You
should generally select the highest frequency filter whose frequency is less
than that of the signal you are measuring, because the higher frequency filters
results in faster measurements. For example, when measuring a signal
between 20Hz and 200Hz, use the 20Hz filter. If measurement speed is not an
issue, choosing a lower frequency filter may result in quieter measurements,
depending on the signal that you are measuring.
