Well you do have to read the manual, and adjust the settings as per your battery type, and charge/discharge rates.
Given your previous question I think my smart shunt has a learning disability you were given directions to a helpful link.
Also you neglected to specify what type of battery you have. Hence the lack of specific detail for settings.
Most importantly, we are not here as volunteers to give instructions verbatim.
You will be given links to the manuals, helpful posts, or even videos to guide your setup.
If you put a little effort in you can get very accurate and repeatable results.
