This meter can measure 0-30V voltage in real , but the percentage of electricity needs to be set to the corresponding string number, otherwise the percentage display will be relatively inaccurate.

Method for setting the number of battery strings
Short circuit the number of strings with tweezers to set the solder pad and negative electrode for two seconds (similar to long pressing a button), and hold for about 3 seconds. The STD character the right side of the screen starts flashing, indicating that it has entered the serial number setting mode. Afterwards, tap the short-circuit string number to set the solder pad and negative electrode, which can cycle between 1-6 strings. The number displayed in the box corresponds to the corresponding string. After stopping the operation for 5 seconds, the system automatically saves and exits the setting mode.
