Hi
I had developed a very simple vi that takes in pressure readings from a peizo electric sensor once in 15 seconds, and displays it in a graph and also writes values it to a measurement file .
However though the pressure is maintained constant the graph shows results fluctuating from +5 to -5 ( almost like a square graph) I am sure that I have connected the have connected my terminals right and also the pressure gauge reads constant one bar pres. I do not know why my readings are fluctuating .
Please help.
Thanks in advance.
