Capacitor Reads Ol. A normal capacitor would have a resistance reading up somewhere in between these 2 extremes, say, anywhere in the tens of thousands or hundreds of thousands of ohms. Web an “ol” or “overload” reading means the capacitance is too high for the multimeter to measure.
Web what does ol mean when testing a capacitor? But not 0ω or several mω. However, i have board with two 0.47uf, 50v electrolytic capacitors and get an overflow message when testing. If your multimeter reads ol while testing a capacitor, it means that the capacitor is damaged and there is no continuity. This result can also mean the capacitor has shorted. It is designed to test capacitors on the board/incircuit and works for many of those i've tested. If possible, use a higher range on your multimeter. A normal capacitor would have a resistance reading up somewhere in between these 2 extremes, say, anywhere in the tens of thousands or hundreds of thousands of ohms. Web before touching it or taking a measurement, a) turn all power off, b) use your multimeter to confirm that power is off and c) carefully discharge the capacitor by connecting a resistor across the leads (as noted in the next paragraph). Web “ol” could be of a different meaning.
Set the multimeter to a higher range if possible. If possible, use a higher range on your multimeter. This is a simple but effective method for finding out if a capacitor is defective or not. Web i'm using a morris #57044 multimeter, which has an autoranging capacitance measurement setting. But not 0ω or several mω. Be sure to wear appropriate personal protective equipment. It is designed to test capacitors on the board/incircuit and works for many of those i've tested. What does it mean when a capacitor reads “ol”? Web before touching it or taking a measurement, a) turn all power off, b) use your multimeter to confirm that power is off and c) carefully discharge the capacitor by connecting a resistor across the leads (as noted in the next paragraph). This result might also indicate that the capacitor has shorted. Web it is reading as if there is an open circuit across the capacitor.
