Meter probes are oh so shiny and conductive but they also like to slip as well as touch other parts you don't want touched. This sort of unwanted touching often leads to nasty sparks and subsequent release of the "magic smoke" form your components.
It may seem "duh" but wait until it happens to you! Things like vintage power output transistors and old chips are expensive to replace. Shorting an output transistor induces big current flows through other parts resulting in collateral damage. One slip can result in multiple burnt parts.
Step 1: Horror! Short Circuit About to Happen!
Step 2: Materials
Step 3: Measure
Step 4: Shrink
Step 5: Done!
What a difference! There is now so much less chance of destroying things if the probe slips. Worst you can do is short the adjacent pin. This should happen only briefly due to the small area of the tip and the fact that you slipped so it's moving.
I hope this simple tip saves you both money and grief in your circuit testing future.
