How to judge whether a Two Pole Distribution Blocks pointer multimeter is good?
This is a relatively big question. It is a better method to try each function range.
When testing, you must first find the test source, but it is impossible for ordinary users to prepare their own standard test source, so the general test can be measured by qualitative plus quantitative methods. The basic solution is to find the test source and then use it once according to the instructions. For example, if the resistance value of the resistor is known, use the ohm range of the multimeter to measure it. If the measured resistance value is consistent with the known resistance value, it means that the multimeter can be used.
