Capacitor Reads Ol. However, if the tested capacitor/capacitance is out of the multimeter range, it’ll show ol, which signifies overload or over limit. Web an “ol” or “overload” reading means the capacitance is too high for the multimeter to measure.
2MC CAPACITOR
Web i'm using a morris #57044 multimeter, which has an autoranging capacitance measurement setting. You could have an electrolytic capacitor that measures exactly what its rated capacitance suggests, but the cap will not work at all in the circuit because its esr is too high. Web it is reading as if there is an open circuit across the capacitor. However, i have board with two 0.47uf, 50v electrolytic capacitors and get an overflow message when testing. But not 0ω or several mω. Web an “ol” or “overload” reading means the capacitance is too high for the multimeter to measure. However, if the tested capacitor/capacitance is out of the multimeter range, it’ll show ol, which signifies overload or over limit. Set the multimeter to a higher range if possible. What does it mean when a capacitor reads “ol”? If your multimeter reads ol while testing a capacitor, it means that the capacitor is damaged and there is no continuity.
It is designed to test capacitors on the board/incircuit and works for many of those i've tested. You could have an electrolytic capacitor that measures exactly what its rated capacitance suggests, but the cap will not work at all in the circuit because its esr is too high. Web i'm using a morris #57044 multimeter, which has an autoranging capacitance measurement setting. Web “ol” could be of a different meaning. Be sure to wear appropriate personal protective equipment. 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 what does ol mean when testing a capacitor? It is designed to test capacitors on the board/incircuit and works for many of those i've tested. This is a simple but effective method for finding out if a capacitor is defective or not. Will a bad capacitor keep a motor from running? Web it is reading as if there is an open circuit across the capacitor.
