2.0 SAFETY
PRECAUTIONS
ALL OPERATORS SHOULD WEAR SAFETY GOGGLES WHEN
USING THIS OR ANY OTHER TACHOMETER. FAILURE TO DO SO
COULD RESULT IN SERIOUS INJURY!
1. Check condition of housing, slide-on Contact Adapter and split
mounting hubs of push-in Contact Cone, Surface Speed Wheel and
any other accessories. Replace those that are worn, loose-fitting or
cracked. The Contact Adapter shaft should rotate freely.
2. When operating in the contact mode, be sure Contact Adapter fits
snugly into the housing grooves.
3. When using the Surface Speed Wheel accessory, make sure it fits the
tachometer shaft snugly. In operation, keep the wheel perpendicular
and parallel to the moving surface to prevent it from running off the
tachometer shaft.
4. Do not use the standard surface speed wheel for speeds in excess of
1000 feet per minute. For higher speeds, specify the optional Heavy-
Duty Surface Speed Wheel with set-screw mounting.
5. Store the instrument in its carrying case when it is not in use.

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.
4. Select the desired units of measure for
surface speed or length by pressing the
MODE key until the appropriate symbol
is shown on the LCD Display.
Surface Speed Length
feet/min feet
meters/min meters
inches/min inches
5. Position the wheel carefully so that it is
perpendicular to the moving surface. Apply
enough pressure to eliminate any slip.
6. Press and hold the Measure key to take measurements.
7. Release the Measure key prior to removing the instrument from the
moving surface. The Last reading will be retained on the display.
