27.1	17	AIS is a video photo recognition sensor, the sensor can be used in electricity meters, gas meters, water meters, pressure gauges and other types of meters. Accurately identify the number of the current dial or upload the picture of the current dial for comparison, which can replace people to go to the door to read the meter, and is more accurate and energy-saving than the meter. The first thing to do is to fix the AIS sensor, the end direction needs to be aligned with the object that needs to be identified, you can check whether the object all appears in the lens range through the upper computer, and then calibrate, Chapter 2 will explain the calibration method of different tables.

	36	The procedure is as follows:
	37
92.4	38	~1. Secure back of the AIS sensor onto the small board and adjust its position according to your requirements. You may use two additional screws for fixation or utilize 3M double-sided adhesive for attachment.

	283
	284	6: Click the exit configuration interface, at this time, there will be a readout. If the Reading of "reading" is consistent with the watch face, the calibration is successful. The AIS cannot move thereafter to avoid misreading.
