Abstract:
A liquid discharging apparatus includes a driving signal creation section that creates a driving signal, a discharge section provided with a piezoelectric element, and a pressure chamber, and a detection section that is capable of detecting residual vibrations. The driving signal creation section is capable of creating a signal having an inspection waveform of which a potential of a first period is a first potential, a potential of a second period is a second potential, and a potential of a third period is a third potential, as the driving signal. The first potential is a potential that is between the second potential and the third potential, and the internal volume of the pressure chamber in a case in which the driving signal is the second potential is smaller than the internal volume of the pressure chamber in a case in which the driving signal is the third potential.
