Product Information
Full details
This guide is for electricians, technicians, and DIY enthusiasts working with electrical systems. The Laser Electrical Test Leads (MPN: 6543) offer reliable voltage and current testing up to 1000V/10A with their durable silicone construction and universal 4mm banana sockets. A potential caveat is their specific 3.8mm OD, which may not fit all clamp meters without adapters. Key features include high voltage/current ratings, flexible silicone insulation, and compatibility with a wide range of multi-meters and accessories.

FAQs
What is the maximum voltage these test leads can handle?
These test leads are rated for a maximum of 1000V.
What is the maximum current rating?
The maximum current rating for these leads is 10 amps.
Are these leads suitable for all types of multimeters?
They are designed for use with most multi-meters that feature standard 4mm banana input sockets.
What does CATIII 1000V mean?
CATIII refers to the transient overvoltage category. A CATIII rating indicates suitability for measurements in building installations, such as distribution panels and fixed motor installations, and provides protection against specific transient overvoltages up to 1000V.
Can I use these leads with clamp meters?
While they have 4mm banana sockets, their 3.8mm OD might not fit directly into all clamp meter jaws designed for inductive current measurement. Compatibility depends on the specific clamp meter design.
How should I clean the test leads?
Wipe them clean with a dry or slightly damp cloth. Avoid using harsh chemicals or abrasive materials.
What should I do if the leads appear damaged?
If you notice any cuts, fraying, or damage to the insulation, stop using the leads immediately and replace them to ensure safety.
Troubleshooting
No reading on multi-meter
Ensure the banana plugs are fully inserted into the test instrument and the probe tips are making good contact with the circuit. Verify the multi-meter is set to the correct function (e.g., Volts AC/DC, Amps) and range.
Intermittent readings
Check the test lead connections at both the instrument and the test point. Inspect the leads for any internal breaks or damaged insulation. Wiggle the cable gently near the connectors to identify loose connections.
Leads feel stiff or brittle
This can happen in very cold conditions. Allow the leads to warm up to room temperature before use. If they remain brittle after warming, the silicone may have degraded, and they should be replaced.
Pros and Cons
Pros
- High safety rating (CATIII 1000V) for user protection.
- Durable and flexible silicone cable material.
- Universal 4mm banana plugs for broad compatibility.
- Sufficient length (122cm) for most common tasks.
- Clearly color-coded for easy identification.
Cons
- Specific 3.8mm OD might not fit all clamp meter jaws.
- Requires compatible accessories for specialized probing (e.g., back probes).
- Primarily designed for use with 4mm banana sockets, limiting some connections.
Setup, Compatibility & Care
Setup: Simply insert the 4mm banana plugs into the corresponding jacks on your multi-meter or other compatible test equipment. Ensure a firm connection. Use the red lead for positive (+) terminals and the black lead for negative (-) terminals.
Compatibility: These leads are designed for use with most multi-meters and test devices that accept standard 4mm banana plugs. They are specifically compatible with Laser accessory part numbers: 6542 (crocodile clips), 6541 (cable piercers), and 6544 (back probes).
Care: Keep the leads clean by wiping them with a dry or slightly damp cloth. Avoid using solvents or abrasive cleaners. Inspect the leads regularly for any signs of damage, such as nicks, cuts, or frayed insulation. Do not use the leads if any damage is found, as this compromises their safety rating. Store them in a dry place, away from extreme temperatures and sharp objects.
