Prescaling
Based on a preset scale, the tachometer converts the number of revolutions to a distance, volume or production per unit time. The prescale function is not included in the TC-4L model.
High Precision
The cycle measurement is used in measurement format to obtain a high degree of precision at low speeds. Using a sampling technique, the tachometer ensures ample precision even at high speeds.
