1.0 INTRODUCTION
The CDT-1000HD Digital Tachometer accurately measures RPM without
contacting the rotating element or object. A small piece of reflective tape
(supplied) is applied to the rotating element (shaft, wheel, etc.) The CDT1000HD utilizes a visible LED light beam to accurately measure the RPM
from a distance of up to 24 inches (60 cm) away from the “target.”
The CDT-1000HD is supplied with a built-in memory system which permits
the user to recall the maximum, minimum and last reading to the display for
viewing. It is powered by two (2) AA batteries (supplied).
1.1 Applications
Non-Contact RPM — Used when contact
measurement is not possible due to access
space restrictions, safety concerns, 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!

8.0 MEMORY SYSTEM
The CDT-1000HD is supplied with
a built-in memory system which
stores the last measurement, maximum
measurement, minimum measurement,
and the average measurement which
occurred during a measuring period.
A measuring period is the interval of time while the Measure key is
depressed. The stored values are retained in memory even when the power
turns off (auto power off). To recall the stored values after auto power off:
1. Press the Measure key to turn the power on
2. Press the MEM key to recall the desired value
The Memory key accesses the CDT-1000HD’s built-in
memory. Each time the MEM key is pressed the values
stored in memory will be recalled to the display in the sequence listed
below. The appropriate memory indicator will be shown together with
the recalled value on the display.
Note: When the batteries are removed, the values stored in memory
will be lost.

7.0 MEASURING RPM
1. Attach a piece of reflective tape to the rotating
element (shaft, pulley, etc.).
2. Aim the CDT-1000HD at the target
using the red visible light beam for
alignment assistance.
3. Press and hold the Measure key to begin taking
measurements. The “On-Target” indicator on the
LCD will flash on and off if the instrument is
properly aimed at the target (reflective tape).
4. Release the Measure key prior to removing the
instrument from the target. The last reading
will be retained on the LCD display.
Hints for Non-Contact Measurements
1. The non-reflective area should be larger than the reflective area.
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.

4.0 OVERVIEW OF CDT-1000HD
4.1 LCD Display
1. On-Target Indicator — Indicates that the unit is lined up
correctly for an accurate measurement
2. Memory Indicators — Indicates which measurement
stored in memory (last, max., min., avg) is displayed.
3. Low Battery Indicator — Illuminates to indicate that
batteries need replacement.
4.2 Front Panel Key Functions
4. MEM: Acesses the memory. Each time the key is pressed
the values stored in memory will be recalled to the display.
5. MODE: Not functional in this model.
6. MEASURE: Performs the following functions:
• Turns on the power
• Starts and stops the measuring period
• Exits from the memory mode

5.0 INSTALLING BATTERIES
1. Turn the gauge over and locate the battery
compartment. You do not have to remove
the rubber shell.
2. Open the battery compartment by pulling
down on the tab located at the top of the
battery cover and remove the cover.
Insert two AA batteries following the
orientation engraved on the inside of the
battery compartment.
3. Replace the battery cover by inserting the
two tabs located on the bottom edge of the
cover into the matching slots in the housing.
4. Push the cover closed until the tab at the top
of the battery cover “clicks” into position.
5. Replace the cut-out section of the protective
rubber shell.
6.0 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.
