614 +
615 +There are two ways to set the device's time:
616 +
617 +
618 +(% style="color:blue" %)**1. Through LoRaWAN MAC Command (Default settings)**
619 +
620 +Users need to set SYNCMOD=1 to enable sync time via the MAC command.
621 +
622 +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]]].

629 +
630 +Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.

961 +
962 +Test the current values at the depth of different liquids and convert them to a linear scale.

964 +
965 +**Example:**
966 +
967 +Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
968 +

970 +Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294

978 +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
