Chapter 10 - Hand Piece Checkout
Procedure for checkout/screening of HP054 Hand Pieces
Note: You must use a calibrated Harmonic GEN 300 for testing hand pieces.
1
Perform the functional test sequence of steps contained in the service manual, Chapter 7 – Safety and Function
Testing (page 23).
2
Power the generator on while firmly pressing both “
Standby
” and “
Min Power-down
” buttons
simultaneously. Continuously press the two buttons until page number 1 of the BME display mode is visible
and only the Standby indicator is lit. A Generator “
Error Code #1
” will result if the two buttons are not
continuously pressed as described and the generator will have to be powered down and back up again. Check
hand piece for loose stud. If the stud is loose, the hand piece is defective and subsequent testing is not
required.
Note: Ensure that the area around the base of the stud is clean.
3
Using the torque wrench for the hand piece, attach the test tip to the hand piece.
Note: Make sure the test tip is not visibly damaged (i.e., dinged or otherwise).
5
Plug the hand piece into the generator
6
Perform a User Initiated Test by pressing the “
TEST
” button. If an error is detected, the hand piece is
defective and subsequent testing is not required.
7
Perform the following while the generator is in Standby:

Record the value of “HP Procedures:” (the estimated number of procedures the hand
piece has been used in)
. In order to record the number, perform the following calculation:
65530 minus the # listed on the display. The hand piece usage counter begins at 65530 and
counts down.
Note: The average hand piece life is 95 procedures, although we have seen hand
pieces go beyond the average life. If the value of HP procedures is getting close to 65435,
then the hand piece is close to 95 procedures.
Approx. Number of procedures = _______________________________

.
Record the value of “PM”
– PM stands for Phase Margin, and a good Hand Piece with a
test tip should be between 170 and 247.
Note: As the Hand Piece ages, the PM decreases; therefore, if the PM is close to 170 or
below, and some of the other parameters are close to their limits, the Hand Piece is getting
closer to its “end of useful life.” Using a Hand Piece that operates near its end of useful life
may result in one or more of the following:
•
generator error codes
•
Hand Piece over heating
•
generator lock outs
