ii . Record the value of |Zr| - |Zr| is the value of the hand piece impedance as
measured by the generator, and for a good hand piece and test tip, this value should
be between 15 and 46 Ohms.
Note: As the hand piece ages, the |Zr| value increases; therefore, if the |Zr| value is
above 40 Ohms the hand piece is approaching 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
|Zr| Value = ________________________________________________
8 Press the standby button to place generator in “ Ready State. ”
9 Activate at level 5 until the pre-run test is complete.
10 Stop activation after pre-run test completes
11 Reactivate at level 5.
12 Record the value of “ impedance ” on the display while continuing to activating at level 5.
Impedance = _______________________________________________
Note: As the hand piece ages, the impedance value increases; therefore, if the impedance
value is above 40 Ohms the hand piece is approaching 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
