Especially in the case of inadequate lighting and noisy environment at the construction site, calibration errors are very likely to occur.

[0003] Using a multimeter to check various cables (for example, 2M head and video head need to touch the inner core and outer shell of the connector with two test leads respectively) or touch different core wires (for example: checking the number of telephone panel and calibrating the clone module) to test the cables is very inconvenient and easy to cause wrong contact, affecting the calibration results. The existing calibration method has the following defects:

[0005] (2) Use a multimeter to check the cable. This requires the operator to have a high sense of responsibility and high operating level. It must be ensured that the test lead and the core wire are in effective contact each time the calibration is performed.

[0006] (3) When using a multimeter to check the cable, two test leads need to be operated by two hands, which means that another person needs to hold the multimeter, wasting manpower.
