To measure rotational speed, point the tachometer's laser at the reflective mark on the rotating object. Ensure a stable hold and press the measurement button to get an accurate RPM reading on the display.
First, check if the batteries are installed correctly and have charge. If the issue persists, replace the batteries with new ones, ensuring they are inserted in the correct orientation.
To ensure accuracy, apply a reflective tape or mark on the object being measured. Keep the laser perpendicular to the surface and maintain a stable hand during measurement.
The Flir Extech 461825 Tachometer can accurately measure up to a distance of about 6 to 8 inches from the target. Ensure the laser has a clear line of sight to the reflective mark.
Consult the user manual for specific button sequences, but typically you can switch units by pressing the 'UNIT' button until the desired unit is displayed.
Regularly clean the laser lens with a soft, dry cloth. Avoid exposing the device to extreme temperatures or moisture. Check the batteries periodically and replace them as needed.
For non-reflective surfaces, it is recommended to apply a small piece of reflective tape to ensure accurate readings with the tachometer.
Ensure that the reflective tape is clean and properly aligned. Check for any obstructions in the laser path and verify that the device is held steady during measurement.
Store the tachometer in a cool, dry place. Remove the batteries if the device will not be used for an extended period to prevent leakage.
The tachometer can measure rotational speeds ranging from 10 RPM to 99,999 RPM, providing versatility for various applications.
