NOTE£º

1. The meter with a range of 50A or 100A must be connected to a shunt before it can be powered on, otherwise it will burn out. Customers who bought 50A or 100A will use it. Customers who don't even buy a shunt, please pay attention! ! Look at the wiring diagram more. Please don't buy if you don't know how to use it, thank you!
2. The power supply range of this meter is 4~30V (it will burn out if it exceeds the range), and the measurement range is 0~100V.

Note: For meters with a measuring range of 50A or 100A, no matter whether the measured current is less than 10A, the shunt must be connected to measure the current! Otherwise, the meter will burn out, and the Voltage display is normal, and the current display is 0.00 or 0.0 Make sure that the thick black wire is connected to the negative pole of the battery andthe thick red wire is connected to the negative pole of the load. (Note that the wiring ofdischarge is different from that of charge. See the following about the concept of loadand power supply). (The meter head uses the original imported chip, which has undergonevery strict testing and calibration before leaving the factory. lf there is no quality prob-lem, it can be sealed and packaged before leaving the factory. 99.99% of the current displays 0, which means the wiring is incorrect. Please check the wiring carefully and patiently.)
