Every Volt/Ohm meter or DMM comes with your basic set of test leads like this. They are great for most applications of probing various points on a circuit board as long as your not dealing with SMD components. Rather then buying another set of leads you can adapt your current set like we had to do in my high school electronics class. Its very simple to do and involves items any electronics hobbiest should already have on hand.
- Set of test leads
- Couple of small metal paper clips
- Wire cutters
- Soldering Iron
Measure out about 1/2" down and place a 90 degree bend in the wire. Place the 90 degree bend of the wire on the end of the test lead and start wrapping the longer end around the lead as tight as you can. Use your pliers to help keep each loop tight to the test lead. After 4 or 5 turns you can trim the leftover piece of wire from the lead. If your only using half the paperclip per lead then wrap it till you run out of wire.
Move the coil to the end of the test lead and bend the top part out, inline with the test lead. Use a good amount of flux all over the coiled part of your new tip. Then using a 40W iron solder the tip to your test lead.
There you have it, a nice new tip for your test lead. Allowing you to better probe smaller components or evaluate test points on a breadboard.
