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.
