1. Introduction
The Amprobe LAN-1 LAN Cable Tester is a diagnostic tool designed to identify and trace data cables and connectors. It helps detect common wiring issues such as shorts, miswirings, and open circuits in various cable types. This manual provides detailed instructions for the proper use, setup, and maintenance of your LAN-1 tester.
The LAN-1 evaluates most common cable types, including 10/100 base-T, 10 base-2, RJ45 modular, AT&T 258A, EIA/TIA 568A/568B, and Token Ring cables, as well as RJ45 and BNC connectors. It can test cables up to 300 meters long and uses LED indicators and an audible buzzer to signal cable status and errors.

5. Setup
5.1 Battery Installation
The LAN-1 tester is powered by one 9V battery, which is typically pre-installed. If replacement is needed:
- Ensure the device is turned off.
- Locate the battery compartment cover on the back of the main unit.
- Remove the screw(s) securing the cover and carefully open it.
- Remove the old 9V battery and disconnect it from the terminals.
- Connect a new 9V battery, ensuring correct polarity (+ to + and - to -).
- Place the battery into the compartment and replace the cover, securing it with the screw(s).
The battery provides power for up to 20 hours of testing.
5.2 Connecting Cables for Testing
Before testing, ensure the cable is disconnected from any active network equipment.
- For patch cables (short cables not installed in walls): Connect one end of the cable to the RJ45 or BNC port on the main unit and the other end to the corresponding port on the remote terminator.
- For installed cables (e.g., wall plates, patch panels): Connect one end of the cable to the RJ45 or BNC port on the main unit. Connect the remote terminator to the other end of the installed cable (e.g., at the wall plate in another room).
6. Operating Instructions
6.1 Powering On/Off
Press the yellow POWER button to turn the device on. Press it again to turn the device off.
6.2 Performing a Test
Once the cable is connected, you can perform a test:
- Press the TEST button to initiate a cable test.
- Automatic Scan (AUTO mode): Press the AUTO button. The tester will automatically scan through each pin (1-8 and G) and display the results sequentially. This is suitable for quick checks.
- Manual Scan (MAN mode): Press the MAN button. Each press of the MAN button will advance the test to the next pin, allowing for a detailed examination of each connection.
- Hold Function: Press the HOLD button to pause the current display of the pin-out indicator. Press it again to resume scanning.
6.3 Interpreting LED Indicators
The 18 red and green LEDs on the PIN-OUT INDICATOR provide visual feedback on the cable's status:
- Green LED: Indicates a correct connection for the corresponding pin.
- Red LED: Indicates an error for the corresponding pin (e.g., open circuit, short circuit, miswiring).
- No LED: May indicate an open circuit or a broken wire for that pin.
- Buzzer: An audible buzzer will sound when an error condition is detected, providing an additional alert.
The LEDs on the remote module will mirror the main unit's display for the corresponding pins, allowing for verification of end-to-end continuity.
6.4 Battery Status Check
Press the BATT button to check the battery level. The BATT LED will illuminate if the battery has sufficient power. If the BATT LED does not light up or is dim, replace the 9V battery.
7. Maintenance
7.1 Cleaning
To ensure the longevity and proper functioning of your LAN-1 tester, keep it clean and free from dust and debris.
- Wipe the exterior of the device with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Ensure no moisture enters the ports or battery compartment.
7.2 Battery Replacement
Replace the 9V battery when the BATT LED indicates low power or if the device fails to power on. Refer to Section 5.1 for detailed battery installation instructions.
Always dispose of used batteries according to local regulations.
