TA200 Laser Photo/Contact Tachometer Introduction Congratulations on your purchase of the Triplett TA200 Laser Photo/Contact Tachometer. The TA200 digital tachometer offers fast and accurate measurements of the following: Rotational speed (RPM) Total Revolutions (REV) Frequency (Hz) Surface Speed (meters per minute, incher per minute, feet per minute, yards per minute) Length (meters, inches, feet, and yards) Features include wide measurement range, high resolution, easy‐to‐read backlit LCD, MAX‐MIN‐...
Description Meter Description 1. Surface (circumference) wheel accessory is shown connected to shaft (rubber cone and concave accessories are also supplied) Adaptor shaft 3. Removable collar (Photo sensor and laser source are located at the top of the meter under this collar) MEM (Memory) button Battery compartment (rear) 6.
Preparing for Measurements Non‐Contact (Photo) Tachometer Preparation 1. Apply a square piece of reflective tape to the surface of the object under test (nominal tape size: 0.5”/12mm). Be sure to affix the tape as close to the outer edge of the object under test as possible.

7. When the MEASURE button is released the last reading will remain on the display for 5 to 10 seconds before the ‘Auto Power OFF’ feature switches the meter OFF. The HOLD display icon will switch ON. Non‐Contact (Photo tachometer) Measurement Considerations Bright ambient light may interfere with the reflected light beam.

Datalog Readings The TA200 can log up to ten (10) “reading sets” for each measurement session (for each unit of measure display). A reading set consists of four (4) values: Initial reading (reading recorded when MEM button is pressed) Maximum reading (MAX icon shown)
Datalogging more than one Reading Set per Measurement Session If the MEM button is pressed momentarily, during a measurement session, the reading set will be created for that measurement session (one reading set for each MEM press). This is useful if more than one ‘initial reading’ is desired for a given measurement session. The MIN/MAX/AVG values logged in each reading set represent the MIN/MAX/AVG values recorded between the MEM presses.
