NI 9205

[Workinghard]

NI 9205 limits voltage to my Labiew program. I can put 0-5 volts DC and all my DAQ assist reading are less than .8 volts

You've programmed it incorrectly or physically wired it wrong. With no information on either, how do you expect anyone to provide an answer. Before doing any coding, did you run the test panel on MAX? Start there.

[Workinghard]

I wasn't to sure what I was doing -  first time - So I have a pressure transduce 0-500psig output 0-5 volts DC. In IMAX -creat a task and checking it works fine. When I make a simple gauge in LabView with a slope of 100 - runing the program the voltage or signal is limited. For instance I can put 300psig and the Fluke reads 3 volts but the gauge on the program only goes to 215 and stops. I can change the slope, the signal input range from 0 -10volts, plus or minus and it will still limit the output.

1. Give us code to look at

2. Show us how you have it wired up.

[Workinghard]

So here is the cDAQ and Mod, with the program. take a look

[Workinghard]

Ok, here is the program. Thanks

1. We can't trace your wires.  Give us a schematic.

2. You are using a bunch of custom scales.  It would be useful to know what they looked like.  Also know that the ranges you put in for the channel should be based on the values AFTER the scale.

[Workinghard]

At the moment I do not have a schematic because I did not wire the system - I know that the sensor are in the RSE. 4 pressure transducer with 24V in and 0-5 out and 3 flow meter with 12Vin and 0-5 out, a load cell with an amp, and a lvdt. It is simple and strengthforward and working on IMAX.

Did you try increasing the signal input range as crossrulz indicated? This range refers to the value after the scale (units of psig). I assume you are creating a task in NI MAX and that is what is working correctly. Are you setting up your DAQ Assistant in LabVIEW the same way you set up your Task in NI MAX?

[Workinghard]

Yes, I normaly have no problem with setting up a strength forward slope of table. To me I there is so kind of limiter in the NI9205. I set up the input to +/-10 volts and there was no change.
