The clamp Meter shows 120A and the Lynx Smart BMS 500 shows 100A.
The Only Load is the Quattro. When i measure the current with a clamp meter the value is about 20% higher and is more realistic with the actual consumption of the Quattro (using a heater for testing.)
Is there a possibility for a ZERO Current Calibration like in BMV menues ?
Hi @Martin_FI,
calibration was done before delivery. There is no feature to re-calibrate except maybe via firmware some day.
20% off seems to be way too much. I have the same device and tested it up to 140A and compared this with a rather cheep clamp meter and additionally with a BMV shunt. Shunt and Smart BMS were spot on while the clamp meter was showing way too much.
If possible put a shunt behind the Smart BMS and see if it reads still too much.
Thank you.
Indeed i made further investigations and found out that the current deviation depends on my load. The load is a heater and it has different heating levels. Only in one heating level I have this deviation. Maybe its because of the mixture of resistive and inductive load in this heating level.
I guess everything is ok and the case can be closed :)
