Introduction
♦ Multirange Current Sensor is used to measure the current in circuit. Sensitive sampling resistor is designed in the sensor. When current passes through resistor, it will form a tiny electric potential difference at both ends of the resistor. After circuit amplifying, it can accurately measure the current in DC circuit or low-voltage AC circuit. Multirange Current Sensor should be series connected to the circuit during using. It can be used to measure the amplitude and direction of current. Internal resistance of Multirange Current Sensor is extremely low. Thus, the resistance it brings to circuit is low. Connecting Multirange Current Sensor will not affect circuit.
Usage
♦ During using, series connect Multirange Current Sensor in circuit. Make sure the current flowing through it from the red wire and flows out from black wire.
Notes
♦ Multirange Current Sensor should be series connected to the circuit during using. Sensor needs to be calibrated before using.
♦ When measuring, please do not make the measured current exceeds the range of the sensor.
♦ If possible, ground the negative pole (black alligator clip) to ensure high accuracy.
