    Hello mahsa,
    Item#200326 doesn’t have UART, so we don’t have communication protocol manual for it.

    Hello ron,
    ru command（read the actual output voltage）
    The format is: aru+0x0d+0x0a
    For example, #ru00000000488 it means the actual output voltage is 4.88V
    ri command (read the actual output current)
    The format is: ari+0x0d+0x0a
    For example, #ri00000000087, it means the actual output current is 0.87A
    Best regards.

    Hello ACMast,
    Thanks for writing in.
    DS18820 is digital temperature sensor, NTC is Analog temperature sensor. So we are not sure if it is suitable for your application. It’s better choose the same type.
    Best regards.

    Hello Roberto,
    Thanks for reply. Base on these information, please try the zero calibration.
    Firstly, please press and hold the SET button without any load, then power the meter. When it displays main window, please release button. After that, zero calibration is finished.
