14
2. Disconnect the wiring socket of the probe from the transceiver, then connect the extension cable to the CT clip.
3. Pass the other end of the extension cable through the transceiver cover, then connect to the transceiver.
4.2 Antenna Installation
Rotate the antenna into the antenna connector. The antenna should be installed vertically and kept away from metal objects and obstacles. Note: Keep the device away from metal objects, obstacles, or the environment surrounded by other electrical equipment that may cause interference. If necessary, please select a magnetic
15
antenna.
4.3 Transformer Installation
Open the current transformer to clip it around a single-phase wire. Then close the clip with a slight “click” sound to make sure the clip firmly grips the wire.
Note: Do not place Phase wire and Neutral wire within a single current transformer.
4.4 Transceiver Installation
The transceiver can be put or hang in any suitable position or to be fixed via cable-ties.
16
4.5 Cable Temperature Sensor Installation (Alternative)
CT10x can monitor the temperature of the wire through the Cable Temperature Sensor, it will alarm when the temperature exceeds the threshold. Pass the Cable Temperature Sensor around the tested wire, and then tighten the buckle. The other end is connected to the CT10x device via the USB Type-C .
NoteKeep the Cable Temperature Sensor as close to the wire connector as possible to better detect the temperature.
