Simply place the Digitest's autoclavable tip on the suspect
tooth and press the "test" button. A gentle, pulsed stimulus
begins to increase at a rate you've pre-selected (slow -medium - fast). Because there are no sudden jumps in power
(as when you twist a knob), the patient feels the stimulus long
before it crosses the "pain" threshold. Large LEDs indicate the
strength of the stimulus.
