3-wire probe wiring mode: the red wire is connected to P+, and the other two wires of the same color are connected to P- and GND (the ports are not distinguished).
Note: Please remove the jumper, otherwise it will affect the accuracy
2-wire probe wiring mode: red wire connects to P+, blue wire connects to P-.
Note: The jumper must be short-circuited, otherwise it cannot be measured! ! !
