SH-22A applies a diamond indenter equipped on a vibrating rod that presses on a test surface at a fixed force and then measures the hardness by fluctuation of ultrasonic vibration.   When the vibration rod is applied to a softer surface object of identical material at a fixed force, it makes a deeper indentation and is constrained. Due to this, the resonance frequency highly increases. Conversely, vibration rod is less constrained when it applied on hard object surface and resonance frequency do less. Hardness value can be calculated using the correlation between the frequency changes and hardnesses.
