Test Leads

Test leads are an integral part of the complete measurement system. Worn out test leads can cause inaccurate readings and pose serious shock or electrocution hazard. Multimeter and Clamp leads are basically a combination of conducting materials such as wires, probes, plugs, and so on. An electrical test leads set, or a kit comprises several copper core wires, a string made of non-toxic silicone, test lead tips with nickel coating, alligator clips with a meter probe, and so on. They have soft and flexible probes which reduce the possibility of breakage. You need to choose the right model of these long meter leads made of silicone. Aside from the standard test leads, there are various test leads such as automotive, spring type, banana type, stacking, extendable, and so on. Alligator clip test leads are suited for electrical testing jobs, and are also used as jumper leads. Triplett offers a huge range of digital test leads for multimeter that can be used with various types and brands of digital multimeters. We offer many meter connector options and test lead sets. Our team also can assist you in finding the correct test lead for your equipment.

Know More About Triplett Test Leads

What Are Electrical Test Leads?

Test leads are primarily wire-like testing and measuring devices. It is used to test and measure the current in a circuit. These are simple devices which are coated and colored to indicate positive and negative with the device connector on one end. On the other end, they have a metal conductor such as an alligator clip or banana tip. Alligator clip leads are widely used. They are slightly different from test probes. Triplett offer superior quality multimeter test lead sets which offer an accurate reading. Quality and accuracy are important because incorrect readings of a meter may be the reason for a mishap. We use good quality similar metals, and hence they do not produce their own voltage when measuring current. Our multimeter lead sets are designed to identify defects in very low voltage circuits as well.

Why Are Test Leads Important in Multimeters?

Multimeter leads are used to identify issues in analog meter as well as digital multimeters. It check the electrical components as well as the circuits. We offer a multimeter test lead kit, wherein the test leads are designed to measure circuits and components in diverse environments. They are important because they help prevent mishaps in the form of shocks, leakages, short circuits, and so on.

How to Use Multimeter Test Leads?

It’s quite easy to use test lead with a multimeter if you follow the process steps. The multimeter device display has resistance and OL outputs. There are a number of buttons of which you may need to push the continuity button. Our test leads are compatible with most multimeter devices and are useful for measuring analog as well as digital circuits. Here are the steps you can follow.

  • Take the black test lead and place it in the COM jack on the multimeter device. After that, place the red test lead and place it in VΩ jack.
  • Check the readings on the device and remove the test leads in the reverse order.
  • Place these test leads on the opposite ends of a component being tested and ensure the circuit is deactivated.
  • Separate the component under test from the other components in the circuit if required.
  • The multimeter will indicate through a beep sound if the circuit path is identified. It will not produce a beep sound in case of any open ends or gaps in the circuit, which means there is an issue.

At What Resistance Should Test Leads on a Multimeter be Discarded?

It is important to inspect the accuracy of the test leads through visual and other tests such as Ohms resistance measurement. This assures the electrical accuracy and reliability of leads. Ideally, good-quality leads have a resistance of around 0.5 ohms or less than that, and the same would be displayed on the multimeter. The multimeter would produce a beep sound for the same; however, it may produce the sound for resistance up to 15 ohms.

To check this, you need to switch on the resistance function of the multimeter and plug the test leads into the device. Do this by placing both the lead tips together. You can do this for one or a single test lead or one at a time. Do not keep it static; you need to move or shake it to check, and do a continuity check. The multimeter and test leads need to work together and offer accurate output. So, check thoroughly if you notice any changes or if the multimeter does not give a beep sound at any point in time. If that happens, you may want to replace your test leads. In fact, if your application demands continual use of test leads or they are exposed to stress environments very often, it is good to replace them once in a year or so.
