Setting the Rotating Speed Measurement Range
(Vertical Scale, RANGE Knob)
This section explains how to set a fixed range.
(If Auto Range in the AUX menu is set to ON, the measurement range changes depending on the
amplitude of the input signal.)
Turn the
RANGE
knob to set the rotating speed measurement range.
• Auto Range in the AUX menu is set to OFF.
• If the input signal type is analog and you turn the RANGE knob when waveform acquisition is stopped,
two values are shown on the measurement range screen. The upper value is the measurement range
for the displayed waveforms. The lower value is the measurement range that you have specified. The
new range will be applied the next time waveform acquisition is started.
• If you do not operate the RANGE knob for approximately 3 seconds, the measurement range that you
are setting with the knob will disappear from the screen.
Top row: Measurement range for the displayed waveforms
Bottom row: Measurement range that you have specified
Use the RANGE knob to display
the measurement range that is
currently being set.
Measurement Range Options and Units
Below are the available options for the RANGE knob, measurement range values, and
measurement range units that appear on the screen for when the zoom method is set to DIV and
the zoom magnification is set to ×1. If you change the zoom method or zoom magnification, what
appears on the screen will change accordingly.
