Automatic MPPT test method: When the [AUTO MPPT] test button is pressed, the multimeter will automatically adjust the test interval time according to the current power value and the digital display.Example: When the solar panel power is 100W, the display will be refreshed every 5S; when the solar panel power is 350W, the display will be refreshed every 15 seconds. When the solar panel power is 700W, the display will be refreshed every 30 seconds.II. Manual MPPT test method: When the [manual MPPT] test button is pressed, the multimeter starts scanning the maximum power point, refreshes the digital display, and keeps the last test result.III. Open circuit voltage detection method: When the multimeter is working, the LCD will display the open circuit voltage of the solar panel in real time.Package List:1 x Solar Panel Multimeter 2 x Connection Cable2 x Clip Cable1 x English Manual1 x EVA KitNote:1.
