Reflective Tape

Laser beam

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 

The displayed temperature units are selected via a slide 
switch located in the battery compartment. To select the 
units (ºC/ºF), 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 50 

to 2000mm (2" to 79"). 

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.
