A look at the Uni-T UT210E

I would have thought an accuracy of a few dozen mA was enough to troubleshoot a car.
EDIT : Milliamps!

As the code is, it will only work for the newer 1106 chip, you MUST uncomment and comment out certain lines for it to work with the older 0660 based models(notes in the code itself on how to do this). Also remember to replace the calibration data from YOUR dump. Otherwise you will have my calibration data.
You can copy/paste directly into IDE from here https://ghostbin.com/paste/6akt4
..or you can download the attached file.
This file does just about every mod to the meter. Simply comment/delete out what you don't want to use.
It would be good if someone could give it a once over for accuracy.

Thanks for the Update Jay , appreciate you adding the 0660 info too for User like me with the Older Chip.
I'll have to let other comments on the Code itself as I am no Arduino Programmer though.

Kbird:
How much precision is needed for automotive use? At low currents it must be difficult to exclude the effect of the Earth's magnetic field.
that was my 1st thought too but I am not an expert on this stuff , so if someone can elaborate , that would be great....

Suggestion: change the code that set 0x56 and 0x57 as follows so that they copy direct from 0x50 & 0x51, rather than using hardcoded values.
//Dotless mode calibration data, copied from 0x50, 0x51
writeByte(I2C_ADDR, 0x56, readByte(I2C_ADDR, 0x50));
writeByte(I2C_ADDR, 0x57, readByte(I2C_ADDR, 0x51));
I wonder if any other bytes can be examined to determine the chipset to selectively run the 0660/1106 specific code?
I haven't yet opened up any of my 3 units to do this or see what chips I have... but soon!

Well, you learn something new everyday.
