calculation for resolution

[fabiogiga]

Hi, I'm a mechanical engineer and amateur in the electronic world. I would like to know what calculation is required to find the resolution using a 6009 DAQ?
thank you!

Hi fabiogiga.

You can use the following formula in order to calculate the resolution:

Absolute Accuracy = ±((Input Voltage * % of reading) + Offset + System Noise + Temperature Drift

You can find more on that here: Differences Between Accuracy, Code Width, and Bits of Resolution
