The Cerbo and multiplus use the same sensor. The BMV does not.
The following thread describes how to calibrate. Suggest you check actual with an IR temp gun.
Thanks Kevgermany but i dont have a IR temp gun and other than this i wouldn't have any use for one . These sensors are supposed to be accurate to 1 degree clearly if i have the correct sensor its out by 800% . Most people would buy a piece of equipment either with the sensor included or buy one separately and just fit it oblivious to its accuracy , that is enough to destroy thousands of euros worth of batteries . How many people would buy something to check the sensor or even question if its accuracy .
My concern now is the sensor that has been controlling the charge voltage of new AGM batteries , has it been 9 degrees out and i have been over half a volt out on the charge setpoints or is the new one 9 degrees out or possibly they both are wrong .
I dont know why the one supplied with the Multiplus and the Type C are not marked in some way to identify them as they look almost identical .
Have now removed it from the Cerbo and fitted it in the Multiplus and its within 1 degree but i guess it would be as i had previously set the offset when it was on the Cerbo
