Hi,
we have a tipping bucket rain gauge connected to a CR1000 over a fairly long distance (50m).
We use the P2 input and the PulseCount() Switch Closure command.
We experience a 50Hz noise being picked up and interpreted as a switch closure. Potentially it comes from the power supply which is connected to a PS100, because we don't see the noise when running the logger on the 9Ah battery with the charge wires to the PS100 disconnected.
I measured the voltage between the P2 and GND terminals and it reads 2.6V.
When we trigger the switch, we experience a bouncing signal and usually read many switch closures for one tipping.
What are your recommendations for filtering the noise and bouncing of the signal?
