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.
How to set Averaging
—Press Meas Setup 4.
—Then More
.
—Then Average N
where N is the current count setting.
— Enter a value using the numeric keypad. Enter 1 for NO averaging.
—Press Enter
.
While Averaging is in process, press Meas Setup 4
, then More, then Restart To
restart the averaging.
Single or Continuous Measure
This setting determines whether the FieldFox measures continuously or only
once each time the Single
button is pressed. Use Single to conserve battery
power or to allow you to save or analyze a specific measurement.
This setting can be changed at any time without affecting calibration accuracy.
How to set Single or Continuous
—Press Sweep 3.
— Then choose one of the following:
— Single
Automatically sets Continuous OFF and causes the FieldFox to
make ONE measurement, then hold for the next Single key press.
When a data trace is displayed, the entire trace is measured, then
holds. The Hold annotation changes to an arrow --> while the
measurement occurs.
— Continuous
Makes continuous measurements. This is the typical
setting when battery power is not critical.
— You can also use Run / Hold +/-
to toggle between Single and Continuous.
