Contact---Surface Velocity/Length Measurement (Figure 8)
Install the contact wheel (0.1m/6in) on the shaft of the mechanical adapter.
Turn on the tachometer. Short press the MODE button to select 0.1m or 0.6in
according to the contact wheel used.
Stop the object under test from rotating or moving.
Short press the UNIT button to select the surface velocity unit (m/min, in/min, ft/
min)
or length unit (m, in, ft).
Long press to start measuring.
.Note: The lock measurement mode can also be used. For details, please see No.2
and No.5 in VII. Buttons.
Make the contact wheel closely contact with the object to be measured.
Start the object under test. The measured value will be displayed on the tachometer
screen.
