In assessing capacitors to determine their current condition the ESR meter is the go-to tool. Simply measuring across a capacitor will quickly indicate its ESR leading to conclusions about if and how far the component has degraded. In most instances this test can be performed while the cap stays in its unpowered circuit, making for rapid testing.
