1.0 INTRODUCTION

The CDT-2000HD Digital Tachometer combines the best features of
contact and non-contact tachometers for measuring rotational speed,
surface speed and length.

When used in the non-contact operating mode, a small piece of
reflective tape is applied to the rotating element (wheel, shaft, etc.).
The CDT-2000HD uses a visible LED light source to accurately
measure the RPM from up to 24” (60 cm) away from the “target”.
In the contact operating mode, the speed is sensed using one of the contact
adapters supplied with the instrument.

In applications where surface speed or linear speeds are to be measured,

the universal wheel is used for direct readout of feet/min, meters/min,

inches/min, meters/sec and feet/sec, as selected by the user.

The CDT-2000HD can also be used to measure the accumulated total of
continuously running material such as paper, wire/yarn being wound on a
spool, or for checking the calibration of on-line counters and totalizer devices.
It will display totals in feet, meters or inches.

1.1 Applications

Contact RPM — Used to measure the speed of
rotating motors, shafts, pulleys, gears, etc.

Non-Contact RPM — Used when contact
measurement is not possible due to access space
restrictions, safety concerns, etc.

Linear Speed and Length — Used to

measure the linear speed or length of
moving surfaces, such as conveyor belts,

printed materials, webs of fabric or

paper, etc.

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
its 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 (DT12) with
set-screw mounting.

5. Store the instrument in its carrying case when it is not in use

12.0 Removing Protective Rubber Shell

The gauge is supplied with a durable rubber shell that provides an added
measure of physical and environmental protection in harsh applications.

To remove the shell, follow the procedure outlined below:

1. Using your thumbs, slide the rubber shell
up and off of one corner of the gauge.
Repeat for the other corner

2. Pull the shell down until it is completely
off the corners of the gauge, the pull the
gauge forward and out of the shell.

3. Replace the shell by sliding the gauge
bottom first into the large center opening,
then, one at a time, slip the corners of the
shell back over the gauge.
