The rev counter utilizes the so-called " stroboscope effect" to analyze 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 1500lx. These flashes of light are emitted in synchronization with the frequency of the movement to be monitored until the object appears to stand still to the observer. The digital tachometer allows the user to focus on specific phases or features of the movement 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 tachometer 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 tachometer 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 percent, users can adjust the light intensity to suit their needs, whether for detailed analysis or wider illumination. The tachometer also offers a phase shift from -360° to +360°. The tachometer has an internal rechargeable battery with an operating time of up to approx. 8 hours.
