Unlike its popular cousin (the PZEM-061) which uses a split-core current transformer (CT), the is typically designed for DC circuits or high-current AC systems using a shunt (external resistor). It measures Voltage (V), Current (A), Power (W), and Energy (kWh/Wh) with a backlit LCD. ⚠️ The shunt must be on the negative
