The meter will only measure the AC component of the signal, the ripple voltage, if present. The display shows the measured value of the ripple voltage amplitude. If it shows the value 0.00 mV it means that, most likely, the ripple is absent. To correctly characterize the ripple voltage, it is necessary to measure its frequency.

To power the ESP32 through its 3.3V pin, we need a voltage regulator circuit to get 3.3V from the battery output. Voltage Regulator. Using a typical linear voltage regulator to drop the voltage from 4.2V to 3.3V isn''t a good idea, because as the battery discharges to, for example 3.7V, your voltage regulator would stop working, because it has a high cutoff voltage.
