SAR V3 Calibration

[HansR]

I have been trying to calibrate the Voltage Reference.
[*]I disconnected the temp wire
[*]In PROGRAM>>CHARGER>>OP MODE? I put AUTO? on FALSE
[*]Put FLOAT? on TRUE
[*]Then went into PROGRAM>>CHARGER>>VALUES>>CALIBRATE?
[*]Tried to DOWN the existing value of 14.3 to 13.60 (the setting of FLOAT), but nothing happens.
What am I doing wrong?
Your advice will be greatly appreciated.

The Emon functions you are attempting only work with the V1 and V2 regulators.

Equalization with the V3 is done using just the V3, not the Emon.

Hi Coulomb,
Thanks for this, but I think you misread my question.

It wasn't about equalization, but about setting the voltage reference. It did have one effect: the voltage shown on Emon is now about 0.7V to 0.8V too high, when compared with a direct reading off the batteries.

Cheers

That amount of error on the Emon is symptomatic of a missing ground. Either the digital ground or the analog ground on TB1 of the Emon. They both need to be connected together at negative distribution.
