Scaling the Y-axis on the
Spectrum display
Select Auto Zoom to adjust the range of the Y-axis for best fit of the measured spectrum.
Select Zoom In / Zoom Out to adjust the zoom.
Select Scale Up/Scale Down to adjust the full scale value on the Y-axis – or select Auto
Scale to select the best scaling for viewing the spectra – without adjusting the zoom.
Auto Zoom and Auto Scale automatically close the drop-down menu, otherwise, select
Close, tap outside the drop-down list or use the left arrow pushbutton to close the
menu. Hint: a quick way of auto zooming is to tap anywhere in the spectrum and then
press the Accept pushbutton twice.
