5. Setup
5.1. Battery Installation
The main unit (tester) comes with a built-in 1250mAh rechargeable lithium battery. Use the provided USB cable to charge the device when the battery is low. The receiver requires a 9V battery (not included). Open the battery compartment on the receiver and insert a new 9V battery, observing correct polarity.
5.2. Initial Power On
Press the power button on the main unit to turn it on. The 3.2-inch color LCD screen will light up. Ensure the receiver is also powered on if you intend to use functions requiring both units.
6. Operating Instructions
The device offers various modes accessible via the mode button and keypad. The LCD screen provides clear visual feedback for all tests.
6.1. Network Cable Length Measurement
Connect one end of the network cable (RJ45, RJ11, BNC) to the main unit's corresponding port. The device will automatically measure and display the cable length. The measurable range is 2.5 to 400 meters (8ft to 1312ft).
Image: Demonstration of measuring network cable length. The tester is connected to a coiled cable, displaying '100.6' meters, indicating accurate measurement.
6.2. Cable Mapping
This function tests for open circuits, crossovers, and short circuits in network cables. Connect one end of the cable to the main unit and the other end to the receiver (or a remote ID adapter if using ET623 with 7 ID). The LCD will display the wiring status.
- Normal: All wires are correctly connected.
- Short: Indicates a short circuit between two or more wires.
- Cross: Shows wires are crossed incorrectly.
- Break: Identifies an open circuit or broken wire.

6.3. Digital Tracing (Scan)
To locate a specific cable among a bundle, connect the cable to the main unit and use the receiver to scan the cables. The receiver will emit an audible tone or vibrate (ET623) when it detects the target cable. Sensitivity is adjustable.

6.4. QC-Connector Crimping Test
This feature allows you to verify the quality of your RJ45 crystal head crimps. Insert the crimped connector into the designated port on the main unit. The device will check the connection and indicate if any wires are improperly crimped or connected.

6.8. Multimeter Functions (ET623 Only)
The ET623 model includes a comprehensive multimeter. Use the provided test leads to perform various electrical measurements.
- AC/DC Voltage: Measure voltage in AC or DC circuits.
- AC/DC Current: Measure current in AC or DC circuits.
- Resistance: Measure the resistance of components.
- Capacitance: Measure the capacitance of capacitors.
- Continuity: Test for continuity in a circuit (buzzer sounds for low resistance).
- Diode: Test diodes.

7. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in its protective case in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: Recharge the main unit's lithium battery regularly, even if not in frequent use, to prolong its lifespan. Remove the 9V battery from the receiver if storing for extended periods.
- Calibration: The device is factory calibrated. If you suspect inaccuracies, contact customer support for assistance.
8. Troubleshooting
- Device not powering on: Check battery level. Recharge the main unit or replace the 9V battery in the receiver.
- Inaccurate length measurement: Ensure the cable is properly connected and undamaged. Verify the cable type is supported.
- Cable mapping errors: Re-crimp connectors if necessary. Ensure good contact between the cable and the tester/receiver ports.
- No signal during tracing: Adjust the sensitivity of the receiver. Ensure the cable is connected to the main unit and the main unit is in tracing mode.
- Multimeter readings are 'OL' (Overload): The measured value is outside the selected range. Select a higher range or check the circuit for faults.

9. User Tips
- For best results in cable tracing, ensure the area is free from strong electromagnetic interference.
- When measuring cable length, ensure the cable is fully uncoiled and free of kinks for the most accurate readings.
- Always turn off the device when not in use to conserve battery life.
- Utilize the flashlight function in dimly lit environments for better visibility during cable work.
