Moreover the good thing about these measuring instruments is that it can be used to measure the esr of a capacitor without the need of removing or isolating the capacitor from the circuit board making things pretty.
The block diagram in figure 1 shows that the esr meter is made up of four fundamental sections. An esr equivalent series resistance meter is useful for measuring the esr of capacitors in circuit and also resistor values that are below one ohm. The charged voltage value is measured via pin a5. The block diagram in figure 1 shows that the esr meter is made up of four fundamental sections.
