For what do you need the password?

What are you trying to do?

I want to learn the functional aspect of studying programming. What's the problem?

Device control tab is used for debugging and device testing if it's not operating as it should.

I recommend you not to touch anything there.

sl~ Engineer?
it's okay-
I'm trying to see changes when practicing with used batteries. All responsibility lies with the user. There is a function in the software, but it doesn't make sense to not know it... Please explain the password creation process... Engineer...

As was already mentioned: Device Control menu is just to diagnose the NLBA1 device itself and has nothing to do with the battery. You should go to the Device Control menu only when the NLBA1 device does not work correctly and you want to debug it.

The password is for calibrating the NLBA1 device. It was already calibrated by us in the production phase, you need to re-calibrate it only after replacing the main chip. So, it is not your case, if I give you the password and you calibrate it correctly then you can damage the device.

Oh~
okay..
 Oh, I understand... Engineer...
