My cerbo GX is reading higher current than my shunt

Hi team,


I am getting nearly 2 amps and 0.1 Volts difference between my Cerbo reading and the actual (tong test and meter) reading on my Batteries.

I have a 1000A smart shunt connected to cerbo via Ve-direct.

I am testing at my battery BUS for voltage and both the negative coming out of the Shunt and positive at the BUS

I think this is related to the battery consumption being lower than the actual as well.

Any ideas?

I found the answer.

I had to do a zero current calibration (which says not usually required.

But this has rectified the issue after carrying it out.
