Page 3: Introduction
1. Introduction R718CK (Ni-Cr / Ni-Si): The detecting range of R718CK is -40°C to +375°C. R718CK has the characteristics of good linearity, bigger thermal electromotive force, high sensitivity, and stability. R718CT (Cu / Cu-Ni): The detecting range of R718CT is -40°C to +125°C. R718CT is more stable when detecting the temperature range of -40°C to 0°C. -

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.

6. Installation 1. The Wireless Thermocouple Sensor (R718CK/T/N/R) 2. When R718CK/T/N/R is compared with the last reported has a built-in magnet (see Figure 1 below). When values, the temperature change is exceeded 10°C installed, it can be attached to the surface of an object (default), it will report values at the MinTime interval. -
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. -
