Change the multimeter probe to an anti-disconnection probe

The above disadvantages can be avoided by making a section of plastic hose on the test lead into an anti-short-line test lead.
The modification method is: find a section of soft plastic tube (such as a disposable medical infusion hose) with a diameter similar to the end of the multimeter pen, use a candle to soften the middle of the plastic tube, pull and rotate it while baking, and quickly put it into cold water after it is softened and stretched thin, so that the stretched soft plastic tube is fixed, and then cut it from the thin part with scissors, cut off the appropriate length, one section covers the test lead, and the other section covers the test lead plug, as shown in the figure.
