Why does the multimeter reading when measuring resistance constantly jump and reset and cannot give an accurate result?

Question

Arduino

I bought an elitech mm 100 multimeter with probes included. When measuring resistance, the value constantly jumps and resets to zero, it cannot give the final result in any way. The call works every other time. I think that the matter is in the probes that came with the kit, but this is just my guess. What is the problem, is it worth buying new probes. If so, which ones? Preferably up to 300 rubles

Answer 1

open the Chinese, tighten the connectors, wash off the flux, look at the board for the quality of the connections, solder the connections and much more ...
that is, conduct quality control (which is not done to reduce the cost of production) and maintenance of the identified jambs.
also with probes.
you're out of luck on Chinese quality roulette :(
the highest quality probes are soldered personally, efficiently and angrily.

Answer 2

With a probability of a dofig percent of the bug in the uncompressed probes. Even my Mastech MS-8268 had a similar problem, although it is a higher class.

Answer 3

Close the probes and insert 200 ohm, it should be 0.1-0.5
Remove the probes and close the connectors with a piece of wire, the measurements should match

Answer 4

The best solution would be to throw out this piece of shit and buy a normal multimeter.
