Operational Guide Summary

Step-by-Step Usage:

1. Setup: Insert the probe cable into the socket on the right side of the device.

2. Power On: Press and hold the power button for 2 seconds to turn the unit on or off.

3. Patient Connection: Attach the file holder to the probe cable and place the mouth hook on the patient's lip.

4. File Attachment: Clip the metal part of the endodontic file to complete the circuit.

5. Measurement: As the file advances into the canal, the color screen displays its real-time position. A reading of 0.5 typically indicates that the file tip has reached the apical constriction – the target working length termination point.
