72.8	272	The PS-LB/LS is configured as (% style="color:#037691" %)LoRaWAN OTAA Class A(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and activate the PS-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

78.1	862	Example:
76.1	863
78.1	864	Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
	865
	866	Calculate scale factor：
	867	Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
	868
	869	Calculation formula：
	870
	871	Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
	872
	873	Actual calculations：
	874
	875	Use this formula to calculate the value corresponding to the current at a depth of 1.5 meters: (6.918-5.035)/1.86470588235294+0.51=1.519810726
