The rev counter utilises the so-called " stroboscope effect" to analyse fast movements, vibrations or periodic processes. With the help of 9 high-intensity LEDs, the speed measuring device generates short flashes of light with an illuminance of up to 1500 lx. These flashes of light are emitted in synchronisation with the frequency of the movement to be monitored until the object appears to stand still to the observer. The digital stroboscope allows the user to focus on specific phases or features of the movement in order to detect defects or irregularities in rotating or oscillating parts.

The flash frequency can be read in both FPM (flashes per minute) and Hz (Hertz). The digital stroboscope has a memory for up to 5 preset flash frequencies so that frequently used settings can be repeated quickly and effortlessly. The one-handed operation makes it easy to control and adjust the settings without complicated menus. The flash frequency is fine-tuned step-by-step on the speedometer using a rotary dial. For quick adjustment of the flash frequency, the stroboscope offers options in steps of 10 and 100 as well as the option to double or halve the flash frequency.

With an LED brightness setting of 10 to 100 per cent, users can adjust the light intensity to suit their needs, whether for detailed analysis or wider illumination. The stroboscope also offers a phase shift from -360° to +360°. The stroboscope has an internal rechargeable battery with an operating time of up to approx. 8 hours.
