Problem with DualCounter

I have DualCounter and little problem. I tried to connect my raingauge to counter. I put my raingauge reed-relay between +5V and Counter1 is that right?

What is good program (free) to reading rain measurements?

It sounds like your connection is correct. What problem are you having?

I use the OneWireViewer for 1-Wire network debugging and testing.

Problem was wire connections wich was correct. Thanks to Eric very quickly answer!!
 
Sometimes my counter counts too much. What went wrong? Electrical disturbances?

Sounds like switch bounce to me. The DS2423 counter chip has internal debounce circuitry but maybe the reed switch in your rain gauge is bouncing more than the DS2423 can handle. There are several debounce circuits on the web that you could try to see if it helps.

Please could you show me one of them... ;)
 
Hi,

are you able to provide picture of unit which are connected to counter ? Especial parts which move (magnet and reed switch)
 

Ups, I must said I am supprised with designe of your device ... from picture is unclear if system use spring to return cup in normal position or not ? ...

System doesn´t use spring and the cup is in normal position. Reed-switch opens when rains 1mm(0.03937inch.) and cup falls down.

What happened if you gently shake your unit ... using reed switch in on (close) instead off in standard position is very problematic design, according DS2423 documentation, counting is triggered on low going signal, what mean in your configuration if for some reason voltage drop, that will be count like one more count ... Eric for sure know more about that

After shaking counter counts 15053mm... :(

Ups, more then i suspect ... are you able to found small Neodymium magnet , and place it together with magnet on your device , that will stronger the force which keep reed switch in close position, and then try to gently sake your device ... I suspect that magnetic force on reed switch isnt strong enough so DS chip are not able to debounce all signals.
