Hello. I'm new and is my first request.
I have a picoscope 2203.
I need to measure two frequency. One output from NRG#40C anemometer (with HALL), and one from a HALL by a wheel with 8 magnet (N-S-N-S-N-S-N-S). The input is a square frequncy signal.
Now when there is no wind the signal may be hold at 0 Vdc or 12 Vdc. And a lot of time all frequency are 0 or 1..2..3...4Hz. When frequency is at 0....data logger read a disturb..not 0Hz.
Can you give me help?
I have also "USB ADC -11/10" picolog and i record with a square signal of 0 - 2.5Vdc but is the same problem.
PicoLog i R.5.20.1
