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.
R718CTAB The temperature/humidity sensor and T-type thermocouple can detect the temperature, humidity, and an object's surface temperature. The temperature measuring range of R718CT is -40°C to +125°C but it works more stably in the range of -40°C to 0°C.
R718CNAB The temperature/humidity sensor and N-type thermocouple can detect the temperature, humidity, and an object's surface temperature. The temperature measuring range of R718CK is -40°C to +800°C, which is wider than other types of thermocouples.
LoRa Wireless Technology LoRa is a wireless communication technology that adopts techniques such as long-distance communication and low power consumption. Compared with other communication methods, LoRa spread-spectrum modulation techniques greatly expand the communication distance. It is used in long-distance and low-data wireless communications like automatic meter reading, building automation equipment, wireless security systems, and industrial monitoring control system. The features include small size, low power consumption, long transmission distance, and anti-interference ability.

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. If the data variation is not greater than the last data reported, the device reports according to MaxTime interval. 3) We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up frequently and the battery will be drained soon. 4) Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, another cycle of MinTime/MaxTime calculation is started.

6. Installation

1. The Wireless Temperature and Humidity Sensor with Thermocouple Sensor (R718CXAB) has a built-in magnet. When installed, it can be attached to the surface 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.

Applications:  Oven  Industrial control equipment  Semiconductor industry
Note: (1) Do not install the device in a metal shielded box or in an
environment with other electrical equipment around it to avoid affecting the wireless transmission of the device.

(2) Do not sink the probe into chemical solutions, such as alcohol, ketone, ester, acid, and alkali.

Screw hole diameter: Ø4mm
2. When R718CXAB is compared with the last reported values, the temperature / air temperature change is exceeded 1°C (default), it will report values at the MinTime interval. If does not exceeded 1°C (default), it will report values at the MaxTime interval.

(3) Please do not disassemble the device unless it is required to replace the batteries.
(4) Do not touch the waterproof gasket, LED indicator light, function keys when replacing the batteries. Please use suitable screwdriver to tighten the screws (if using an electric screwdriver, it is recommended to set the torque as 4kgf) to ensure the device is impermeable.

3. Do not put the whole stainless probe into the liquid. Sinking the probe into the liquid could damage the sealing compound and thus cause the liquid to get inside the PCB.

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. This lithium chloride layer prevents rapid self-discharge caused by continuous reaction between lithium and thionyl chloride, but battery passivation may also lead to voltage delay when the batteries are put into operation, and our devices may not work correctly in this situation.
As a result, please make sure to source batteries from reliable vendors, and it is suggested that if the storage period is more than one month from the date of battery production, all the batteries should be activated. If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.

ER14505 Battery Passivation:
7.1 How to tell a battery requires activation
Connect a new ER14505 battery to a resistor in parallel, and check the voltage of the circuit. If the voltage is below 3.3V, it means the battery requires activation.

7.2 How to activate the battery
a. Connect a battery to a resistor in parallel b. Keep the connection for 5~8 minutes c. The voltage of the circuit should be 3.3, indicating successful activation.
