1. Introduction
This manual provides essential information for the safe and effective use of the Metrel A 1015 Blue Test Leads. These test leads are designed for use with specific Metrel instruments, including MI 3101, MI 3105, MI 3102, MI 3100, MI 3002, MI 3125B, MI 3122, and MI 3121. Please read this manual thoroughly before using the product.
2. Safety Information
Always adhere to the following safety precautions to prevent injury or damage to the equipment:
- Ensure the test leads are in good condition before each use. Do not use if insulation is damaged or wires are exposed.
- Verify that the test leads are rated for the voltage and current of the circuit being tested.
- Always connect the test leads to the instrument first, then to the circuit under test. Disconnect from the circuit first, then from the instrument.
- Avoid touching the metal tips of the test leads when connected to a live circuit.
- Use appropriate personal protective equipment (PPE) such as insulated gloves and safety glasses.
- Refer to the instruction manual of the specific Metrel instrument for additional safety guidelines.
3. Product Overview
The Metrel A 1015 test leads are a set of high-quality, blue-colored test leads designed for electrical measurements. They feature standard banana plug connectors for compatibility with various Metrel testing instruments.
Figure 1: Metrel A 1015 Blue Test Leads. This image shows the two blue test leads with their insulated cables and banana plug connectors.
Each lead consists of a flexible insulated wire terminated with a banana plug on one end and a test probe on the other. The blue color helps in easy identification and organization during testing procedures.

4. Setup
To set up the Metrel A 1015 test leads with a compatible instrument:
- Ensure the Metrel instrument (e.g., MI 3101, MI 3105) is powered off.
- Locate the input terminals on your Metrel instrument. These are typically color-coded or labeled for specific functions (e.g., V, COM, A).
- Insert the banana plugs of the A 1015 test leads firmly into the corresponding input terminals of the instrument. Ensure a secure connection.
- Once connected, the instrument is ready for use with the test leads. Refer to your instrument's manual for specific connection diagrams and measurement procedures.
5. Operating Instructions
The Metrel A 1015 test leads are passive accessories. Their operation is directly tied to the Metrel instrument they are connected to. Follow these general guidelines:
- Measurement Selection: Select the appropriate measurement function (e.g., voltage, resistance, continuity) on your Metrel instrument.
- Probe Placement: Carefully place the test probes onto the points of the circuit you wish to measure. Ensure good contact.
- Reading Results: Read the measurement results directly from the display of your Metrel instrument.
- Live Circuits: When working with live circuits, always connect the common (usually black) lead first, then the live (usually red or blue) lead. Disconnect the live lead first, then the common lead.
6. Maintenance
Proper maintenance ensures the longevity and accuracy of your test leads:
- Cleaning: Clean the test leads with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure they are completely dry before storage or next use.
- Inspection: Regularly inspect the insulation for cuts, cracks, or signs of wear. Check the connectors for corrosion or damage. Replace damaged leads immediately.
- Storage: Store the test leads in a clean, dry environment, away from direct sunlight and extreme temperatures. Avoid sharp bends or kinks in the cables.
7. Troubleshooting
If you encounter issues while using your Metrel A 1015 test leads, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| No reading or unstable reading | Poor connection to instrument or circuit; damaged lead; incorrect instrument setting. | Ensure leads are firmly connected. Inspect leads for damage. Verify instrument settings. |
| Physical damage to insulation | Wear and tear; improper handling. | Discontinue use immediately and replace the test leads. |
| Corrosion on connectors | Exposure to moisture or harsh environments. | Clean connectors carefully with a suitable contact cleaner (ensure instrument is off). If severe, replace leads. |
