: Some technical terms are phrased awkwardly, which can be confusing for beginners.
The thin yellow and white wires coming from the shunt are the signal wires. They are polarity sensitive. If your meter shows a negative current (e.g., "-5.0 A"), simply swap the wires on Terminals 3 and 4. peacefair pzem-051 manual
While it is flashing, short-press the button once to clear the energy data. The display will stop flashing and reset to 0000 .
