Principle of apex locator operation
Micro signals consisting of dual frequencies sent from the unit return to the unit after travelling along the electronic circuit that is composed of: unit-probe cord-file holder-file-patient-lip holder-probe cord. The impedance of the electric circuit may be changed depending on the distance between the end of a file and the apex of the root canal, which results in a change in the micro signals that are input back into the unit.The microprocessor of the unit calculates the change in micro signals to convert the difference into a distance value,which will be displayed on the FreePex LCD display.
