frequency-counter-operating

It can measure from 16Hz to 100Hz signals with a maximum amplitude of 15V. The sensitivity is high, the resolution is 0.01Hz. The input signal can be a sine, a square or a triangle waveform.

The counter can be used in many applications. For instance, to observe an oscillator’s accuracy, to measure the mains frequency or to find out the rpm of a motor that is connected to an encoder.
