620 +=== 2.6.2 Set Device Time ===
621 +
622 +
623 +There are two ways to set the device's time:
624 +
625 +
626 +~1. Through LoRaWAN MAC Command (Default settings)
627 +
628 +Users need to set SYNCMOD=1 to enable sync time via the MAC command.
629 +
630 +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]]].
631 +
632 +Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.
633 +
634 +
635 + 2. Manually Set Time
636 +
637 +Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
638 +
639 +
640 +=== 2.6.3 Poll sensor value ===
641 +
642 +Users can poll sensor values based on timestamps. Below is the downlink command.

1366 +== 6.4 How to measure the depth of other liquids other than water? ==
1367 +
1368 +
1369 +Test the current values at the depth of different liquids and convert them to a linear scale.
1370 +Replace its ratio with the ratio of water to current in the decoder.
1371 +
1372 +Example:
1373 +
1374 +Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1375 +
1376 +Calculate scale factor：
1377 +Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1378 +
1379 +Calculation formula：
1380 +
1381 +Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1382 +
1383 +Actual calculations：
1384 +
1385 +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
