1. Unit voltage calibration: by adjusting the "system reference voltage" (about 3.0 by default), slowly increase and decrease the amplitude of 0.001, the unit voltage value can be changed until it is accurate! 2. Total voltage calibration: by adjusting the "total voltage ad value into the actual voltage of the parameters" (default about 3330), slowly adjust the size of this value, you can change the total voltage until accurate! 3. Current calibration: by adjusting the "current sensor range", slowly adjust the value, you can change the current until it is accurate
note: please do not change the item of "power starting current" in parameter setting, too large may lead to MOS tube burning and discharging!!!
