1. Introduction
The Fluke 2042 is a professional general-purpose cable locator designed for tracing cables in walls and underground, locating fuses/breakers on final circuits, and locating interruptions and short-circuits in cables and underfloor heating. It is suitable for both live and dead cables, offering reliable and precise results.
2. Safety Information
Always adhere to local safety regulations and guidelines when operating the Fluke 2042. This device is rated to EN61010-1 CAT III 300V. Observe the following precautions:
- Do not use the device if it appears damaged or operates abnormally.
- Ensure proper connection of the transmitter and receiver before applying power.
- Avoid contact with live circuits unless specifically instructed and with appropriate personal protective equipment.
- Refer to the CAT III 300V rating for maximum voltage handling.
- Only use the device for its intended purpose as a cable locator.
3. Components
The Fluke 2042 system consists of two main units: the Transmitter (2042T) and the Receiver (2042R).
Figure 3.1: Fluke 2042 Cable Locator (Receiver and Transmitter)
The image displays the two primary components of the Fluke 2042 Cable Locator system. On the left is the Fluke 2042R Receiver, a yellow handheld device with a large LCD screen at the top, displaying "SENSE 9", "CODE F", and "LEVEL". Below the screen are several control buttons, including a power button, a light button, a UAC button, and navigation/selection buttons. The bottom part of the receiver shows "FLUKE 2042R RECEIVER". On the right is the Fluke 2042T Transmitter, also a yellow rectangular device with a dark grey face. Its LCD screen shows "Volt 12 50 120 230 400", a warning triangle, "CODE F", and "LEVEL" bars. Below the screen are two circular buttons, one green and one black, and "FLUKE 2042T TRANSMITTER" at the bottom. Both units are designed for robust field use.
3.1. Fluke 2042T Transmitter
- LC-Display: Shows transmitting level, transmitting code, and external voltage (12V, 50V, 120V, 230V, 400V).
- Output Signal: Generates a 125 kHz signal for tracing.
- Voltage Range: Operates with voltages up to 400 V AC/DC.
- Frequency Range: 0 - 60 Hz.
3.2. Fluke 2042R Receiver
- Backlight LC-Display: Displays level of receiving signal, code of receiving signal, and live voltage indication.
- Sensitivity Adjustment: Allows for automatic or manual adjustment of receiving signal sensitivity.
- Acoustical Signal: Switchable audio feedback for signal detection.
- Torch Lamp Function: Integrated light for working in dark environments.
- Tracing Depth: Capable of tracing cables 0-2.5 m in walls/underground.
- Main Voltage Detection: Detects main voltage from 0-0.4 m.
4. Setup
Before first use, ensure both the Transmitter and Receiver have sufficient power. The units come with batteries included.
4.1. Battery Installation/Check
While batteries are included, it is good practice to check their charge level. Refer to the battery compartment on each unit for access. Ensure batteries are inserted with correct polarity.
4.2. Connecting the Transmitter
Connect the transmitter to the circuit or cable you wish to trace. The Fluke 2042T can be connected to live or dead cables. Use the appropriate leads and adapters for your application. Ensure all connections are secure before powering on the transmitter.
5. Operating Instructions
The Fluke 2042 is designed for ease of use, providing clear signal identification through its digitally coded sender signal.
5.1. Basic Cable Tracing
- Power On: Turn on both the Transmitter (2042T) and the Receiver (2042R).
- Connect Transmitter: Connect the 2042T to the cable or circuit to be traced. For live circuits, ensure the voltage is within the specified range (up to 400V AC/DC).
- Select Mode (Receiver): On the 2042R, select the appropriate mode (e.g., automatic or manual sensitivity adjustment) using the control buttons.
- Trace Cable: Move the 2042R Receiver along the suspected path of the cable. The display will show the signal level and code. The acoustical signal can be switched on for audible feedback.
- Identify Signal: The digitally coded signal ensures that you are tracing the correct cable, preventing false readings from other sources. The "CODE" display on both units should match.
- Pinpoint Location: The signal strength (LEVEL) on the receiver's display will increase as you get closer to the cable. Use this to pinpoint the exact location.
5.2. Advanced Functions
- Live Voltage Indication: The receiver's display will indicate the presence of live voltage, enhancing safety during operation.
- Torch Lamp: Activate the integrated torch lamp on the receiver for improved visibility in dimly lit areas.
- Multiple Signals: Additional transmitters can be used to distinguish between several signals in complex installations.
6. Maintenance
Proper maintenance ensures the longevity and accuracy of your Fluke 2042 Cable Locator.
- Cleaning: Clean the device regularly with a damp cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a dry, cool place, away from direct sunlight and extreme temperatures. Refer to storage temperature specifications.
- Battery Care: Although batteries are included, if the device is to be stored for an extended period, it is recommended to remove the batteries to prevent leakage.
- Calibration: For professional use, periodic calibration may be required to maintain accuracy. Consult Fluke's official support for calibration services.
7. Troubleshooting
If you encounter issues with your Fluke 2042, try the following steps:
- No Signal/Weak Signal:
- Ensure both transmitter and receiver are powered on.
- Check battery levels in both units.
- Verify proper connection of the transmitter to the cable.
- Adjust the receiver's sensitivity (manual mode).
- Ensure the cable is within the tracing depth range.
- Incorrect Readings:
- Confirm the "CODE" displayed on the receiver matches the transmitter's code.
- Minimize interference from other electrical devices.
- Display Issues:
- Check battery levels.
- Ensure the backlight is activated if working in dark conditions.
If problems persist, contact Fluke customer support.
