การตั้งค่า

1. การติดตั้งแบตเตอรี่

The tachometer requires a 9V battery (not included). To install, open the battery compartment located at the bottom of the handle, insert the 9V battery, ensuring correct polarity, and close the compartment securely.

2. Applying Reflective Tape

For accurate non-contact measurements, a small piece of reflective tape must be applied to the rotating object. Ensure the tape is clean and securely attached to a flat, non-reflective surface on the object. Only one piece of tape is typically required for measurement.
