When it is sleeping, it does not collect data. 10 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. 11 6. Installation 1. The 3-phase current meter (R718N3) has a built-in magnet (see Figure 1 below). It can be attached to the surface of an object with iron during installation, which is convenient and quick. To make the installation more secure, please use screws (purchased separately) to fix the device to the wall or other objects (such as the installation diagram). Note: Do not install the device in a metal shielded box or in an environment surrounded by other electrical equipment to avoid affecting the wireless transmission of the device. 4. The 3-phase current meter (R718N3) samples the current according to MinTime. If the current value sampled this time relatively exceeds the set value (the default is 100mA) more than the current value reported last time, the device will immediately report the current value sampled this time. If the current variation does not exceed the default value, the data will be reported regularly according to MaxTime. 5. Press the [Key] of the device to start sampling data and report the data after 3 to 5 seconds. Note: MaxTime must be set greater than Min Time. 2. Open the clamp-on current transformer, and then pass the live wire through the current transformer according to the installation. Note: "LK" is marked on the bottom of the CT. 3. Precautions: Before using, user must check whether the appearance is deformed; otherwise, the test accuracy will be affected. The using environment should be kept away from strong magnetic fields, so as not to affect the test accuracy. It is strictly forbidden to use in humid and corrosive gas environments. Before installation, please confirm the current value of the load. If the current value of the load is higher than the measurement range, select a model with a higher measurement range. The three-phase current detector (R718N3) is suitable for the following scenarios: School Factory Shopping mall Office building Smart building Where the electrical data of the device with the three-phase electricity needs to be detected. 12 Current Direction The CT terminal should be close to the power terminal as much as possible.

CT Wire to be detected Phase C The CT terminal should be close to the power terminal as much as possible. Installation Diagram 1. When using it, the back of it can be adsorbed on the iron surface, or the two ends can be fixed to the wall with screws. 2. When installing the R718N3 series current transformer, please separate the live and neutral wires of the wire to be detected, and only take the live wire through current transformer and start the measurement according to the wiring below: Neutral Wire Detected Object L K Live Wire Power Supply CT Wiring Schematic Diagram (Current direction KL) 13 If the live wire and the neutral wire are connected together at the same time, they will offset each other and the measurement is 0. L K Neutral Wire Live Wire Note: Please do not disassemble the device unless it is required to replace the batteries. 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. 14 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. 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 To determine whether 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. Brand Load Resistance Activation Time Activation Current Note: NHTONE RAMWAY EVE SAFT 165 67 67 67 5 minutes 8 minutes 8 minutes 8 minutes 20mA 50mA 50mA 50mA If you buy batteries from other than the above four manufacturers, then the battery activation time, activation current, and required load resistance shall be mainly subject to the announcement of each manufacturer. 15 8.
