7.0 MEASURING SURFACE SPEED OR LENGTH
1. Install the Slide-on Contact Adapter.
2. Slide the Surface Speed Wheel over the shaft of the
instrument. Be sure to align the pin on the side of the
shaft with the slot in the adapter. Push on securely.
NOTE:
If using optional surface speed wheel,
refer to Section 8.0 before continuing.
3. Select the desired units of measure
for surface speed or length by
pressing the MODE key until the
appropriate symbol appears on the
LCD Display.
The units of measure appear in
the following sequence:
RPM
➔ m/min ➔ m/sec ➔ ft/min ➔ ft/sec ➔ in/min ➔ m ➔ ft ➔ in
4. Position the wheel carefully so that it is
perpendicular to the moving surface. Apply
enough pressure to eliminate any slip.
5. Press and hold the MEASURE key to take
measurements.

Hints for Non-Contact Measurements
1. The non-reflective area should be larger than the reflective

2. If the rotating element is highly reflective, cover it with black
tape or paint to improve the contrast between the reflective
tape and the surface of the rotating element.
