Multimeter leads are wires used with analogue and digital multimeters for testing and identifying problems. Multimeter leads are used for the testing of electrical components and circuits. They can be used to measure voltage, current and resistance. Test leads feature a connector, such as a jack, to connect to the multimeter and another connector for testing, such as a probe, crocodile clip or banana plug. Multimeter test leads are considered an essential part of electrical measurement.
Test leads must be in good condition. If the test leads are faulty, this can lead to inaccurate readings and could result in a health and safety concern if live wires are being read as being de-energised. Therefore it is important to keep your test leads in good condition and replace them when necessary. A lead kit for measuring high voltage and high energy circuits, such as distribution system voltages (240V- 600V), needs to be high quality, with the proper markings and product ratings. You should always take precautionary steps to verify the condition and rating of the leads before testing to ensure safety in the workplace.
We have a range of available connector types to suit your needs, including crocodile clips, banana plugs, angled plugs and retractable plugs, as well as application-specific kits, such as automotive, electrical and industrial kits.
We also offer a variety of Multimeters & Accessories for all your testing needs.
Checking your Multimeter Leads:
- Confirm that the multimeter and multimeter test leads are rated for the category and voltage level appropriate for the electrical environment they will be used in. Electrical measurement category ratings are defined by the safety standard, IEC61010 and have four ratings, CAT I, CAT II, CAT III and CAT IV.
- Inspect the leads to make sure they are safe to use and able to conduct electrical signals accurately. This includes checking that the leads are properly insulated with no cracks through the cables and also checking the connectors are clean and debris-free.
- Complete a visual inspection first then conduct simple ohms measurement to confirm they are electrically reliable and able to carry a signal within allowable loss parameters.
