DAQ 6210 Accuracy

Solved!

Highlighted

I've got a DAQ NI-USB 6210 and a distance sensor with 0-10V analog output depending on 50-250mm disctance.
Therefore I configured NI Max with an input range of 0-10V.
According to this Accuray table I would measure 10V+2.69mV (accuracy) or 10-2,69mV at 300mm distance.
What about the accuracy at 5V and 100mm distance?
I know that the resoultion with 16 Bit ADC would be better with a 0-5V input range than 0-10V.

But what about the absolute accuracy. Could I measure a 5V signal in 0-10V range with accuracy of 1.4mV to 1,5mV or would be the accuracy from 2 to 2,69mV?

I've got no reference to compare this two configurations.

Nominal Range Positive Full Scale (V) Nominal Range Negative Full Scale (V) Residual Gain Error (ppm of Reading) Residual Offset Error (ppm of Range) Offset Tempco (ppm of Range/°C) Random Noise, σ (μVrms) Absolute Accuracy at Full Scale (μV) Sensitivity (μV)
10 -10 75 20 34 229 2,690 91.6
5 -5 85 20 36 118 1,410 47.2
1 -1 95 25 49 26 310 10,4
0.2  -0.2  135 40 116 12 88 4,8

There is no 0-10V range available.  You will be in the -10-10V range.  Therefore your accuracy will be in the 2.7mV range.
