(2) If the MinTime configuration is less than 20 seconds, it will configure 20 seconds. (3) R718N360 series would take about 3 seconds for the CT to sample and process the collected value, If the current changes frequently, the sampling result might be wrong. - Page 7 ChannelCRawData(4Bytes) Example 1 of Uplink: 01CA019F000002A9000000 byte (01): Version byte (CA): DeviceType – 0xCA – R718N360 byte (01): ReportType byte (9F): Battery – 3.1V Battery=0x9F, binary=1001 1111, if bit 7= 1, it means low voltage.

Target load current value= “R718N360 read value” / (“R718N360 read standard load value” / “standard load current value”) When R718N360 is connected to the CT which needs to be used, it is necessary to obtain the conversion coefficient k first. - Page 12 Formula 2: Target load current value= “R718N360 read value” / (rawdata * 500 * CT transformation ratio) / (0.18 * 8388608) mA Example: R718N360 reads the value 925. CT transformation ratio: 3000:1 The current value of the target load = (925*500*3000) / (0.18*8388608) = 918.904940287mA...

Page 14: Information About Battery Passivation
7. Information about Battery Passivation Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high.
