Introduction Congratulations on your purchase of Extech's Laser Photo/Contact Tachometer with NonContact 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.
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.
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). RPM Contact Tips CONTACT LINEAR SURFACE SPEED (ft/min or m/min) MEASUREMENTS 1. Install the Linear speed wheel on the contact shaft. 2.
NON-CONTACT TEMPERATURE MEASUREMENTS 1. Point the meter at the surface to be measured. 2. Press the red 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. IR thermometer button. WARNING: Do not directly view or direct the laser pointer at an eye.
