• Velocity (Velocity)
Velocity (km/h) = distance per pulse l (km) ÷ Tw (s) × 3600
Velocity (m/s) = distance per pulse l (m) ÷ Tw (s)
You can define unique distances and units (angular velocity and other units).
Measurable range: F (= 1/Tw) = 0.01 Hz to 500 kHz

Offset (Offset)
By setting an offset, you can move the waveform to a vertical position that is easier to see. You can set the offset
for each channel.

Selectable Range of the Offset
The range varies depending on what is being measured.
• When measuring frequency: ±(Value/div) × 1000 or 500 kHz
• When measuring revolutions in rpm: ±(Value/div) × 1000 or 50 krpm
• When measuring revolutions in rps: ±(Value/div) × 1000 or 1000 rps
• When measuring periods: ±(Value/div) × 1000 or 50 s
• When measuring duty ratios: ±(Value/div) × 1000 or 100%
• When measuring power frequency: You cannot set an offset.
• When measuring pulse widths: ±(Value/div) × 1000 or 50 s
• When measuring pulse integration: ±(Value/div) × 1000 or 1.0000E+22
• When measuring velocity: ±(Value/div) × 1000 or 1.0000E+22
Notes about Setting the Offset
Changes to the offset are not applied when acquisition is stopped. The changed offset will be applied to the next
measurement.
• The offset does not affect cursor-measurement values, automated measurement values of waveform
parameters, or computed values.
• You can change the position of the waveform relative to the vertical position (change the focus of the
vertical zoom) by changing the offset.
