Introduction
♦ Milli Current Sensor is used to measure the current in circuit. Internal resistance of Milli Current Sensor is extremely low. Thus, the resistance it brings to circuit is low. Connecting Milli Current Sensor will not affect circuit.
Usage
♦ During using, series connect Mill Current Sensor in circuit. Make sure the current flowing through it from the red wire and flowing out from black wire. The measured current value is positive under this condition as shown below:
Notes
♦ When measuring, please do not make the measured current exceeding the range of the sensor. If the current is too high, please connect current limit resistor.
♦ Be careful of connection of input wire.
♦ Short connect input wire before measuring to calibrate the sensor.
♦ Be careful of effect of contact bounce especially the bounce caused by sliding rheostat.
♦ Never parallel connect Milli Current Sensor to power supply otherwise extremely high current will be produced and damage the sensor permanently.
♦ Do not use high voltage or domestic AC.
