The calibrated version includes only the calibration of the optical system. It features a single memory. This tachometer has an integrated optical transmitter and receiver on the top of the device, as well as a mechanical contact unit at the base. The 5-digit LCD automatically inverts when switching between optical and contact-based operation, ensuring the display is always oriented correctly. It functions as a photo tachometer for direct readings in RPM and as a contact tachometer with direct reading ranges in RPM, m/min, and ft/min. A memory recall of the last measurement is also available.
