Frequently Asked Questions
What does CAT rating mean on test leads?
CAT ratings indicate safety levels for transient voltage environments. CAT III covers building installations; CAT IV covers outside distribution. Higher ratings protect against voltage spikes.
Are silicone leads better than PVC?
Silicone offers superior flexibility and temperature resistance. It remains pliable in cold weather and resists cracking under heat. PVC is cheaper but less durable in extremes.
How often should I replace test leads?
Replace leads when insulation is damaged or connectors loosen. Regular inspections prevent hazards. Quality leads last years with careful handling.
Can I use these for automotive testing?
Many sets work for automotive diagnostics. Ensure voltage ratings match vehicle systems. Use back probes for harness connectors to avoid damage.
What if my plugs don't fit the meter?
Most modern meters use four mm plugs. Older models may require adapters. Always verify compatibility before buying to avoid returns.
Do I need alligator clips?
Clips enable hands-free testing. They are useful for voltage monitoring. Consider kits that include them to save cost.
