I have just installed a BMV Smart to monitor 12v 525ah house bank and auxiliary starter batteries. Both banks are showing Min Battery Voltage in the history page of 0.02v. What did I do wrong?

Sorry to take so long to get back to you. I've just cleared the history as mentioned above. Minimum battery voltage went from 0.02V to the correct 27.12V.
If you do it, much quicker to go backwards from the first option than forwards 62 times.
I think it's simply the lowest reading from before the batteries were connected. Values look good now. So don't worry, expect to see normal readings from now on.
It shows you the lowest voltage ever measured so it will not change on it's own.
You need to reset the history, look in the manual for that.
Thinking more about it, it's to be expected if there's been any disconnection of the battery, this will occur and be retained permanently. I just checked the manual. It's possible to clear history data, look in section 4.2, option 63.
