How to measure the resistance and the resistance of a capacitor with a multimeter?
Multimeter red and black pen are respectively connected with the capacitor anode (before each test, the capacitor discharge), by hand swing to judge the quality of capacitor. If the hands quickly to the right, and then slowly left back in situ, general capacitor is good. If the needle is placed after that has no turning capacitor breakdown. If the needle swing up gradually after the return to a stop position, the capacitor have leakage. If the needle is put up, that the capacitor electrolyte has dried up push lost capacity.
A general mechanical watch can measure whether or not the capacitance is on the ground, short circuit, leakage, and capacity...... So, let you control the measured capacitance mark data to determine the good / bad, but not a difference of capacity (digital table can measure the capacity of this gear); resistance can be detected according to the measured electrical resistance, color ring to control mark progenitor resistance related chart data can judge for themselves a good / bad. Specifically, you read Baidu library, there are plans, there are text to teach you.
The resistor file can roughly identify the quality of the capacitor above 5000PF (5000PF can only judge whether the capacitor is broken or not). Check the resistance range in the range of high value, two probes are respectively in contact with the capacitor, the pointer swing fast and restoration, reverse connection, the swing amplitude is greater than the first, and then restored. Such capacitors are good.
