Averaging
Averaging helps to reduce the effects of random noise on a measurement. The
FieldFox computes the displayed value over several consecutive readings.
Average count determines the number of readings to average. The higher the
average count, the greater the amount of noise reduction.
An average counter is shown in the left edge of the screen as
Avg N
. This
shows the number of previous readings that have been averaged together.
When the counter reaches the specified count, then a ‘running average’ of the
last
N
readings is displayed.
Average count = 1 means there is NO averaging.
This setting can be changed at any time without affecting calibration accuracy.
