AC filter applies to ACV, ACI and FREQ/PERIOD measurements. It can optimize the
low-frequency accuracy and minimize the AC settling time. DM3068 provides three
types of AC filters (slow, medium and fast). The AC filter to be used is determined
by the input signal frequency.
Input Frequency AC Filter
3 Hz to 300 kHz Slow
20 Hz to 300 kHz Mid
200 Hz to 300 kHZ Fast
In ACV, ACI or FREQ/PERIOD measurement, press

Press Slow, Mid or Fast to select 3 Hz, 20 Hz or 200 Hz as the lowest frequency of
the AC filter. The default is 20 Hz: MEDIUM.
