How to Use the Standard Test Leads 4 mm

Check that the apparatus uses compatible 4 mm sockets or terminals
Inspect each test lead for damaged insulation, loose plugs or exposed conductor
Connect one end of the lead to the power supply, meter or circuit component
Connect the other end to the matching circuit terminal
Use different colours to separate positive, negative and signal connections
Switch on the circuit only after all connections are secure
Switch off the supply before changing or removing leads

Safety note: Use the leads only within the confirmed voltage and current rating. Do not use damaged leads, wet leads, loose plugs, or leads connected directly across a power supply output.

Care & Maintenance

Coil the leads loosely after use to prevent conductor breakage
Store the set in a dry drawer, pouch or laboratory accessory box
Clean plugs with a dry cloth if dust or oxidation affects contact
Replace any lead with cracked insulation, bent plugs or intermittent continuity

Completing the Circuit-Building Station

Schools building a full circuit-wiring station often pair Test Leads 4mm Set of Ten with a Universal Plugboard for rearranging circuits quickly, Resistors for Breadboard for current-limiting and voltage-division practice, and the Stabilized Laboratory Power Supply 0-15V / 3A DC as a repeatable bench power source.

Frequently Asked Questions

What are 4mm test leads used for?
4mm test leads are used to connect power supplies, meters, plugboards, switches, bulbs and other electrical components in classroom circuit experiments.

How many leads are included in this set?
