123.2	300	The PS-LB/LS is configured as 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.

	637
	638
123.2	639	~1. Through LoRaWAN MAC Command (Default settings)
93.1	640
	641	Users need to set SYNCMOD=1 to enable sync time via the MAC command.
	642
	643	Once CPL01 Joined the LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to CPL01. If CPL01 fails to get the time from the server, CPL01 will use the internal time and wait for the next time request ~[[[via Device Status (FPORT=5)>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/CPL01%20LoRaWAN%20Outdoor%20PulseContact%20%20Sensor%20Manual/#H2.3.1DeviceStatus2CFPORT3D5]]].

93.1	646
	647
123.2	648	2. Manually Set Time
93.1	649

76.1	1292
	1293
76.2	1294	Test the current values at the depth of different liquids and convert them to a linear scale.
	1295	Replace its ratio with the ratio of water to current in the decoder.
76.1	1296
123.2	1297	Example:
76.1	1298
78.1	1299	Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
	1300
123.18	1301	Calculate scale factor:
78.1	1302	Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
	1303
123.18	1304	Calculation formula:
78.1	1305
	1306	Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
	1307
123.18	1308	Actual calculations:
78.1	1309
	1310	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
