Introduction:
Micro Current Sensor is used to measure tiny current signal in circuit. Sensitive sampling resistor with 300Ω 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, voltage is direct proportional to current. It can accurately measure the micro current.

Calibration:
TS2103 Micro Current Sensor needs to be calibrated before using. Connect sensor to datalogger. Open SWR iLab. Short connect red and black alligator clips to calibrate.

Usage:
During using, series connect Micro 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:

Product General Assembly
Experimental procedures:

1. Connect apparatus as shown above. Calibrate micro voltage and current sensor.
2. Open the SWR iLab V8.0. Click 'new' to create new experimental template. Click 'new page' to add new folder.
3. Click 'add line' to add 'Micro voltage-Time' and 'Micro current-Time' curve. Set proper experiment time and acquisition interval.
4. Click 'start' and move bar magnet to change the flux passes through circuit.
5. Click 'stop' when collecting is completed. Observe induced voltage, current change with respect to time.
6. Observe and analyze the experimental result.
7. Clear up the apparatus

Notes:
1. Micro Current Sensor should be series connected to the circuit during using. Micro  Current Sensor needs to be calibrated before using.
2. When measuring, please do not make the measured current exceeding the range of the sensor.
3. If possible, ground the negative pole (black alligator clip) to ensure high accuracy.
