The Improvement of Multimeter Zero Adjustment Button
In some multimeters, the zero-adjustment knob is too thin, and it is laborious and inconvenient to turn the knob during zero-adjustment. At this time, toothpaste can be used to increase the height.
The method is: use a layer of 502 glue on the toothpaste cover, paste it in the center of the original knob, and after it is dry, a beautiful zero adjustment knob will be successfully changed.
