5 seconds. Until the data of three-axis accelerometer is lower than InActiveThreshold, and the duration is more than 5 seconds, R718E would send two packet, one is the data of three-axis accelerometer, and the other would be sent after 10 seconds with the data of the speed of three-axis &... -
Page 7: Activethreshold And Inactivethreshold
The 0g offset or offset is an important accelerometer indicator because it defines the baseline used to measure acceleration. After installing R718E, turn on the device and wait for the device join the network 1 minute, the device will automatically offset the calibration. -

Page 11: Example Application
6. Example Application In the case of detecting if the generator is working normally, it is recommended to install R718E horizontal while the generator is power-off and in static status. After installing and fixing R718E, please turn on the device. After the device is joined, one minute later, R718E would perform the offset calibration of the device (the device cannot be moved after the offset calibration. -

Page 13: Information About Battery Passivation
8. 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. -
Page 14: Important Maintenance Instruction
9. Important Maintenance Instruction Kindly pay attention to the following in order to achieve the best maintenance of the product: • Keep the device dry. Rain, moisture, or any liquid, might contain minerals and thus corrode electronic circuits. If the device gets wet, please dry it completely.
