DIY milliohm/volt meter kit

Nicely done.

[robrenz]

Yes, very nice work on all of the project.   


What about calibration for the reference resistor error?

What about calibration for the reference resistor error?

Yes, it does need to be calibrated, not sure what the non calibrated accuracy is. Calibration is a simple procedure as long as you have a know resistance that matches the range being calibrated.

As I don't have any resistance standards, or meters with equal resolution. I measured a reasonably low tempco, high wattage, wire wound resistor using a 5A current source and a volt meter and then used that as my reference.

Does anyone have the documentation for this project (hopefully in English but I will take what I can get)?

Let me know your email address via PM and I'll send you the documentation.

I apologize for reopening this old thread

I'm looking for the firmware modified by Jaxbird. Can someone help me ? Thank you !
