One switch position = one unit! You can choose between 7 units of measurement using the rotary switch:
min-1 (tr / min) - m / min - Hz - ms - Duty% - RPM - ft / min.
In the counting function you can measure directly in meters, feet or number of pulses. With the same device, you can measure the number of revolutions as well as speeds and pulse frequencies or the opening time of relay contacts. With the tachometer and speedometer, 3 types of measurements can be carried out: contactless, with contact or via an external measurement input.
