Today, a review of multimeters from the Polish manufacturer SONEL: CMM-11 and CMM-30. These devices are industrial multimeters with increased resistance to operation in difficult conditions. They have a maximum reading of 4000 and 6000. Is their accuracy at a decent level?
I check the functionality of multimeters (continuity test, diode test, measurement time), resistance to falls and flooding with water, and accuracy. How will these multimeters rank among the measuring devices I have already tested?
