TRACEABLE® LASER/PHOTO TACHOMETER INSTRUCTIONS

SPECIFICATIONS

Resolution: 0.1 below 1,000 RPM
1 above 1,000 RPM
Accuracy: ±1 RPM or 0.05%
Sampling Time: 1 second (over 60 RPM)

Measuring
Distance*: 2 to 78 inches (50-2000 mm)

(*Measurement distance will vary depending on ambient light,
environmental conditions and the size of the refl ecting surface.)

Laser Output: 1mW
Laser Wavelength: 600-700 nm

LASER TARGETING

Laser targeting is always active when the Measurement button is being
pressed. Each time the Measurement button is pressed and held, the laser
beam will be emitted.

CAUTION: Class II Laser Product. Do not stare into the laser beam.

OPERATION

Cut a strip of the refl ective tape into a 0.5" square.1.
Stop the rotation of the object to be tested.2.
Make certain that the surface of the rotating object is smooth and clean 3.
so that the refl ective tape will adhere properly and place the refl ective
tape on the object. The refl ective tape may be placed on either the end
of the rotating object or circumference (surface) of the rotating object.

Measurement Notes–

The non-refl ective area of the object must be greater than the refl ective tape
surface. If the object to be tested is normally refl ective, it must be covered
with black tape or black paint before attaching the refl ective tape.

MEMORY RECALL

The memory feature allows the last, highest, and lowest readings to be
recalled. Readings are normally retained in memory for several minutes.

Upon completion of measurement–

Press and hold the MEMORY button to display the last reading recorded 1.
prior to releasing the Measurement button. The display will alternate
displaying the RPM value and LA (last).
Release the MEMORY button.2.
Press the MEMORY button a second time to display the highest reading 3.
recorded. The display will alternate displaying the RPM value and UP
(highest).
Release the MEMORY button.4.
Press the MEMORY button a third time to display the lowest reading 5.
recorded. The display will alternate displaying the RPM value and dn
(lowest).

ALL OPERATIONAL DIFFICULTIES

If this tachometer does not function properly for any reason, replace
the batteries with new high quality batteries (see Battery Replacement
section). Low battery power can occasionally cause any number of
“apparent” operational diffi culties. Replacing the batteries with new fresh
batteries will solve most diffi culties.

BATTERY REPLACEMENT

Erratic readings, faint readings, no display, or LO appearing on the display
are all indications that the batteries must be replaced. Open the battery
compartment by sliding the battery cover in the direction indicated by the
arrow. Remove the exhausted batteries and replace them with four (4) new
AA alkaline batteries. Make certain to install the new batteries in the directions
indicated in the battery compartment (improper battery placement may cause
damage to the electronics). Replace the battery cover.

Use particular care when measuring the rotation of the fl at end of a shaft
with a relatively small diameter. Completely cover the fl at end with non­refl ective black tape. Place the 0.5" square refl ective strip on top of the black
tape as close to the edge as possible.

If the rotation being measured is less than 50 RPM, increase the accuracy
of the measurement by applying additional refl ective tape on the rotating
object. Place the additional refl ective tape approximately 180 degrees from
each other (on opposite sides of each other). To determine the actual RPM
of the rotating object, divide the displayed RPM reading by the number of
refl ective tape pieces.

Allow the object to rotate. Press and hold the Measurement button 4.
(located on the right side of the unit) and point the laser beam at the
refl ective tape.
Verify proper alignment by observing the location of the laser and by 5.
checking the display. When properly aligned, each time the refl ective

results.
