Measuring Relative Frequency
You can measure the difference in frequency from one measurement to another
(drift) using the Relative Frequency function. You do this by pressing the
Shift
and
Rel Freq
(
Offset On/Off
) keys as shown in the diagram below (this example
assumes that a signal is currently applied
to Channel 1).
The Counter stores the current frequency reading when you press the
Rel Freq
key. It then subtracts this value from all subsequent readings and
displays the difference until you press the
Rel Freq
key again.

NOTE
If the input signal fluctuates, the value displayed varies as the Counter continues
to take measurements. You can vary the speed at which measurements are taken
by varying the settings for Rate and Resolution (see
“Setting the Resolution for Frequency Measurements”
and 63).
