How to Use a 100V 10A DC LED Voltage/Current Meter
In this tutorial, we learn how to wire, how to measure current, how to measure voltage, how to test the accuracy of current measurement, and also show you how to calibrate the meter to get correct values. We also measure and calculate the value of the shunt resistor used in this meter. At the end of this tutorial, you will see that some modules sold online are different internally.
