NI6008 wrong input voltage reading from C# ex.; Labview shows the correct value

[LazyLiz]

Hello there, I am a newbie in C#, so I start learning it from the provided examples in NI module.

I try to collect the input data from my circuit...first I tried with the labview, it showed about the same value as I got from the voltmeter; C# showed the totally different.

Ex. Voltmeter = 0.3V, Labview = 0.35V, C# = -1.015V.

Am I missing something?

I solve my own problem. I didn't notice I can change the channel configuration to RSE, then the offset from default mode (-1.4V) can be neglect.
