" ** Not for ESR it isn't. "
True, but a circuit's tolerance for ESR varies widely.
A 100 uF with 5 ohms ESR might totally upset one but work fine in another.
** Listen, you context shifting bloody idiot !!!.
An ESR test establishes the **condition** of a given electro cos the bastards have a LIMITED service life !!!!!!
A cap that tests 5 ohms ESR when it ought read 0.5 ohms is totally WORN OUT and needs immediate replacement before it stops working as a cap all together and/or spews electrolyte over the PCB and other components destroying them.
