Why does the multimeter behave like this?

Question

Electronics

Hello! Help to understand the problem. I bought an inexpensive, but good multimeter - the reviews seem to be good. But there is a problem in it, it shows readings only if the probes are pressed down hard. What could be the problem? After all, usually only a slight contact is enough.

Answer 1

Clean the dipsticks with a scissor or replace.
Some do not understand what kind of coating they have: it shines, but does not contact normally

Answer 2

Maybe you poke into a varnished board?
