NOTE
• If a reading seems to be a multiple of what you expect, the input signal
may be distorted. Distortion can cause multiple triggerings of the
frequency counter. Selecting a higher voltage range might solve this
problem by decreasing the sensitivity of the multimeter. In general, the
lowest frequency displayed is the correct one.
