Two wire system voltage meterSelf calibration method:

One在车载电压表正常工作状态时.长按"output使能"KeyTwoAfter Two seconds, the voltmeter flashes,

Two轻触"output使能"Key. Voltage rises in one unit"low power consumption"The key. The voltage is reduced to a unit, because the voltage value of a unit is less than0.1VSo you need to connect

Continuous press
1-5Time to see the voltmeter changes0.1VThe specific number of consecutive keys depends on the current display voltage value. The higher the current display voltage,


Note: this kind of adjustment method you only need to be calibrated once can get the accurate voltage value in the entire voltage range. This function is designed to meet your higher accuracy requirements
