According to the customer's frequent questions, make the following summary reference: Note: The meter with a range of 50A or 100A must be connected to the shunt to measure the current no matter whether the measured current is le than 10A! Otherwise it will burn the header. Voltage display normal, current display 0.00 or 0.0 Make sure that the thick black wire is connected to the negative pole of the battery, and the thick red wire is connected to the negative pole of the load. (Note that the discharge is not the same as the charging connection, see the concept of load and power supply.) (The header uses the ed ch, after the factory paed very strict testing and calibration, to ensure that no quality probl before leaving the factory. The current display shows 0 99.99% is the wiring is not right, please be patient and carefully check the wiring) Current display is not accurate: If it is a direct power supply or an independent power supply and device power supply are common ground, as long as the fine black line can be disconnected accurately. Connecting to power does not appear: All AC power rectified power must be filtered by an electrolytic above 1000uF to supply power to the meter. Judging the quality of the header (the following are two cases of normal headers) Without shunt, connect the thin red line and the thin black line to the power supply. The meter current of 50A shows 50.0~59.9, and the meter of 100A shows 100~109. Connect the shunt, connect the thin red line and the fine black line to the power supply. The meter current with a range of 50A shows 0.00, and the meter with a range of 100A shows 0.0; Other considerations: The current can only be measured on the negative side of the power supply and on the negative side of the load. Voltage range: The power supply voltage range of the 5 line header is 4~28V, that is, the voltage of the thin red line cannot exceed 28V. About the concept of load and power During discharge: The battery, switching power supply, and transformer are power supplies, and the s, lamps, motors, and power devices are the loads. When charging: The charger, , and solar energy are power supplies. The and the battery are the loads.Package Include:
