BMV-602s idle current changing

I have a BMV-602s that has been giving different current readings from the very beginning. IT will give a few hundred mA current reading with no loads attached for some time after disconnecting the loads. Then after some time it will read zero current.


If I disconnect the loads then zero the current reading all is fine for a while then the current will shift and start displaying a charge (due to the zeroing offset).


I have fully isolated the battery cable at the battery isolation switch and searched for parisitic loads to no avail. The only load on the isolated battery is the actual BMV. I've also tried to make sure that the BMV to shunt cable and connectors have no problems.


Any thoughts? Is this a know fault to the BMV602s?

Hi,

Check the BMV manual ito Zero'ing the current and also to Synchronize it.

Must be done every now and then as the settings to slide a wee bit over time. Perfectly normal.
