5. Setup
5.1 Component Identification
Familiarize yourself with the various ports and interfaces on the measurement box and display unit.
5.2 Hall Sensor Types
The Hall sensor is crucial for current measurement. Two types are available:
- Standard Closed Hall Sensor: The ring cannot be opened.
- Optional Open Hall Sensor: The ring can be opened and installed without removing wires.
5.3 Wiring Diagrams
Proper wiring is essential for accurate and safe operation. Refer to the diagrams below for different power supply and relay configurations.
- Two-wire power supply wiring diagram: Connects the measurement box directly to the battery for power.
- Three-wire external power supply wiring diagram: Uses an external power source for the measurement box, adjusting the jump cap to the 3/W position.
- Discharge relay wiring diagram: Shows how to integrate a discharge relay for automatic control.
- Charging relay wiring diagram: Shows how to integrate a charging relay for automatic control.
Important: Ensure all connections are secure and polarity is correct before powering on the device. Incorrect wiring can damage the instrument or the connected battery.
6. Operation
6.1 Display Descriptions
The 2.4-inch color LCD provides a clear overview of all measured parameters. Refer to the diagram below for an explanation of each display element.
6.2 Introduction to Curves
The device can display waveform curves for voltage, current, and temperature, providing a visual representation of parameter changes over time.
7. Maintenance
- Environmental Conditions: Keep the instrument in a dry environment. The working temperature range is -10~50℃, and the storage temperature range is -20~70℃.
