My Lynx shunt m10 version is reporting 0,3V lower than any other device in the system. I take readings from multiplus ii, 2 smartsolar chargers, 2 jk bms. Is there anything i can do to fix it? I tried zero calibration but nothing changed.
Verified with a meter?
Or are all other device exactly the same and the shunt is the one that is different?
Yes i checked it with the meter. All other devices are ±0,1V
I probably needed to be more specific.
Does the shunt agree or disagree with the meter?
The meter agrees with the bms, i tried measuring in the shunt terminals but its always -0,3V
Is the voltage drop you measured while the system is under load? A load will make a no-load voltage drop even worse.
If there is no load then it could be due to poor connections or inadequate wiring. Poor connections can be improperly prepared contact surfaces (oxidation that wasn’t cleaned off), loose connections or bad crimps.
The bad thing is that i had measured at the lynx connection and the dmm shows +0,3
