- Page 3 1. Introduction R718CKAB The temperature/humidity sensor and K-type thermocouple can detect the temperature, humidity, and an object's surface temperature. The temperature measurement range of R718CK is -40°C to +375°C. R718CK has the features of good linearity, larger thermal electromotive force, high sensitivity, and stability. It should not be used in sulfuric environments, reducing, oxidizing, vacuum atmospheres, or weak oxidizing atmospheres.

- Page 14 Note: 1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data. 2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value, the device reports according to MinTime interval.
- Page 15 6. Installation 1. The Wireless Temperature and Humidity Sensor with Applications: Oven Thermocouple Sensor (R718CXAB) has a built-in Industrial control equipment magnet. When installed, it can be attached to the surface Semiconductor industry of an object with iron which is convenient and quick. To make the installation more secure, use screws (purchased) to secure the unit to a wall or other surface.
- Page 16 7. 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 17 8. Important Maintenance Instructions Kindly pay attention to the following 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.
