Calibration system and calibrating method

A calibration system adapted to calibrate a resistance of an electrical device having a lead wire, comprising:

• a resistance detector adapted to detect the resistance of the electrical device;
• a first container containing an etching solution adapted to etch the lead wire;
• a heater configured to heat the electrical device;
• a robot adapted to grip the lead wire;
• and
• a security grating located at an entrance of the calibration system and adapted to detect whether an external object enters into a working area of the calibration system, and when the security grating detects that the external object enters into the working area of the calibration system, the calibration system immediately stops working,
• wherein, with the electrical device at a first temperature, if a first resistance of the electrical device detected by the resistance detector is within a first predetermined range, the robot is adapted to:
• heat the electrical device with the heater to a second temperature higher than the first temperature and detect a second resistance of the electrical device with the resistance detector;
• and
• if the second resistance is beyond a second predetermined range, place the lead wire into the etching solution to etch the lead wire for adjusting the resistance of the electrical device until the second resistance at the second temperature is within the second predetermined range.
