The external shunt must be connected correctly to the "Current" terminals to measure high amperage safely. en.peacefair.cn Peacefair PZEM-051 is a DC digital multi-function meter

• If current flows from Battery to Load: Positive Power.
• If current flows from Charger to Battery: The display will show a negative symbol (-) before the power, and the kWh will decrease (counting backwards).

, the meter will exit the reset state without clearing the data. 2. Voltage Alarm Threshold Setting (SET) If current flows from Battery to Load: Positive Power
