1. How to test a capacitor without capacitance measurement If only a simple multimeter without a function for capacitance measurement is available, then only the rough functionality of the capacitor or electrolytic capacitor (electrolytic capacitor) can be checked.
In summary, the best solution to test a capacitor without desoldering it actually for the circuit board is either using an ESR meter or smart tweezers. Both work the same and are fine to use. But the ESR meter is preferred for through-hole capacitors, and the latter one is preferred to test SMD capacitors.
There is left one choice we can use to test a capacitor, and that is by measuring its equivalent series resistance (ESR). You know, when the capacitor is in use for a long time. Its capacitance value tends to decrease because the capacitor dries out with time, but its internal resistance value increases.
This stored voltage is called electrical capacitance (C) and is measured in Farad (F). Since electrolytic capacitors wear out over time, it may be necessary to check their functionality. You can measure a capacitor with the multimeter.
Even with these Multimeters, we can test a Capacitor. Remove the Capacitor from the circuit or board and make sure it is completely discharged. Set the Multimeter to measure resistance i.e., set the knob to Ohm or Resistance Settings.
You just cannot test a bad capacitor inside or outside a circuit board by measuring its capacitance value with a capacitor meter or a multimeter. Because in such a situation mentioned devices lead you into false reading, and you may not be able to actually tell if the capacitor you tested was actually a bad or right one. Why?
Attach a fuse (where the fuse rating is calculated using the formula: In = 0.8 / C (A), where C is the capacitor''s capacitance) in series with the capacitor and connect them to a 220V AC power supply. Observe the Fuse: …
