Voltage acquisition - instable reading

Hello,

 

We're using SignalExpress for acquisition of voltage signal from chemical analyser (0-10V or 0-5V).

After the connection of our last analyser the signal reading is very instable despite of the stable value from analyser output.

Could you help us to resolve this problem ?

Hello,

 

Can you tell us more about your hardware? What card do you use to acquire your signal?

 

Do you have screenshots of the analyzer output and the signal reading from SignalExpress?

 

Have a nice day!

Clement
