Trying to Calibrate JK BMS

[BigBrosMo]

I am trying to set the calibration voltage on my JK 8S BMS but every time I tap "OK" it says system entry failure. Why? I read it has to have a very low load, so I disconnected everything and tried again - still no joy. Any ideas? TIA

Did you ever get this resolved?

Yes and no. Not really, but kind of. Does that help?

I figured out that the only values it would accept are within a range of what it measures. eg. If I measure 26.8v with my volt meter, and the BMS is showing 27v, I can calibrate it to something like 26.92 but not to 26.91 or lower. So I can get close to my volt meter but not exactly. It annoys me as that drives the current reading off over time from my battery monitor (which has no calibration settings) and yet is dialed into my Volt meter.

If you figure it out, or acquire any insight let me know!
