Laser Photo / Contact Tachometer
with IR Thermometer
Patented
Introduction
Congratulations on your purchase of Extech's Laser Photo/Contact Tachometer with Non-
Contact IR Thermometer, Model RPM10. This Tachometer provides contact RPM and
Linear Surface Speed measurements, non-contact RPM measurements and IR
temperature measurements. The laser pointer beam provides accurate long distance
measurements for photo tachometer measurements and also identifies the measurement
spot for the non-contact temperature tests. This meter, with proper care, will provide years
of safe reliable service.

Meter Operation
Reversible LCD Display
The meter display indicates Photo Tachometer and IR thermometer measurements in one
direction and Contact measurements in the opposite direction. This permits the user to
easily read the measurement digits in both measurement modes with the meter held in
either direction.
Temperature Units Selection
Cal switch,
Do not move
The displayed temperature units are selected via a slide
switch located in the battery compartment. To select the
units (ºF/ºC), open the battery compartment and remove
the batteries, then set the switch for the desired units.

NON-CONTACT PHOTO TACHOMETER MEASUREMENTS
1. Apply an appropriately sized square piece of reflective tape to the surface of the object
under test.
2. Move the Function switch to the PHOTO position.
3. Point the laser pointer end of the meter toward the device under test at a distance of 2"
to 79" (50 to 2000mm).
4. Press the Measure button (located on the right side of the meter) and align the laser
pointer beam with the reflective tape.
5. Verify that the ((●)) Monitor Indicator appears on the LCD when the object under test
passes through the light beam.
6. Release the Measure button when the RPM reading stabilizes on the LCD.
7. If the rpm is under 50, apply additional squares of reflective tape. Divide the reading
shown on the display by the number of pieces of reflective tape squares to calculate
the actual rpm.
NOTE: Bright ambient light may interfere with the reflected light beam. Shading the target
area may be necessary in some cases.
CAUTION: Rotating objects can be dangerous. Use extreme care.

CONTACT TACHOMETER RPM MEASUREMENTS
1. Install one of the RPM contact tips on the contact shaft.
2. Move the Function switch to the CONTACT position.
3. Press the Measure button while lightly pressing the contact tip
against the center of a rotating shaft.

4. Release the Measure button when the display stabilizes
(approx. 2 seconds).
CONTACT LINEAR SURFACE SPEED (ft/min or m/min) MEASUREMENTS
1. Install the Linear speed wheel on the contact shaft.
2. Slide the Function Switch to SURFACE SPEED “ft/min" or
"m/min" position.
3. Press the Measure button and hold the surface speed wheel
against the moving surface being measured.
4. Release the Measure button when the display stabilizes
(approx. 2 seconds).

NON-CONTACT TEMPERATURE MEASUREMENTS
1. Point the meter at the surface to be measured.
2. Press the red
IR thermometer button.
3. Use the laser pointer to identify the exact spot to be measured.
4. The area of the surface to be measured must be larger than the spot size as
determined by the distance to spot size specification.
5. Read the temperature in the display.
WARNING: Do not directly view or direct the laser pointer at an eye. Low power
visible lasers do not normally present a hazard, but may present some potential for
hazard if viewed directly for extended periods of time.

MIN/MAX and Last Reading Memory Recall
The meter will record Maximum, Minimum, and Last Reading for the period of time the
Measure button is held. These stored values can then be recalled directly on the meter's
display. The readings will remain in the display for approximately four seconds after a
button press.
1. Press the Memory key once: The “Last” icon appears with the stored last reading.
2. Press the Memory key again. The “MAX” icon appears with stored maximum reading
3. Press the Memory key again. The “MIN” icon appears with stored minimum reading
