Micro voltage sensor
The voltage sensor is connected to the red and black wires with alligator clips. The method of use is similar to that of a voltmeter. When using, the voltage sensor is connected in parallel in the circuit. If the red wire of the micro voltage sensor is connected to the high potential end of the circuit, and the black wire is connected to the low potential end, the displayed value is positive; if it is connected reversely, the displayed value is negative.
* Note: The voltage to be measured cannot exceed the range of the sensor!
