(2) In Peak Search function with Marker
Function key Description
Peak Search
One marker will automatically find the peak signal and
show the frequency and amplitude.
6.2.3 Track Peak signal
Function key Description
Peak Search
One marker will automatically find the peak signal and
show the frequency and amplitude.
F6
ON/OFF>
The marker will continuously find the peak signal and move
to the center when the track is on.
Or manually operate one step a time.
Function key Description
Peak Search
One marker will automatically find the peak signal and
show the frequency and amplitude.
F2
Center>
The marker will move frequency marked to the center.
6.2.4 Make correct amplitude measurement
Function key Description
Amplitude Select the amplitude relative functions.
F1
Set the top level of display.
Note: The input signal exceeding the reference level will
cause error in the harmonic related measurement.
F2
Select the scale to zoom in/out the amplitude for
observation.
F3 Select the unit as wanted. The scaling between the units is
automatically done.
