4.1.2.2 Digital Filter

Definition:
M3510A/11A uses an averaging digital filter to yield a reading for display
from a specified number of measurement readings in the past. The past
measurement readings are stored in a stack of memory. The number
may be in the range of 2 to 100. You may select one of the two modes of
digital filter operations: Moving Average and Repeating Average.
The moving average filter puts the specified number of reading
conversions in a first-in, first-out order. The very first measurement
reading simply fills up the stack. To yield a reading for display, the filter
produces an average of the stacked measurement readings every time
when a new measurement reading is available and replaces the oldest
reading in the stack. In the repeating average mode, the multimeter
waits for the measurement reading stack to fill up and then take an
average to produce a reading for display. It then flushes the stack and
starts over with an empty stack. Consequently, the repeating digital filter
yields one reading for display every specified number of measurement
readings.
Note: Digital filter is not available for diode, continuity, frequency and
※
period measurements.
Default
The digital filter is enabled and is in moving average mode with 10
