Dynatron® 850plus & 550plus
Ultrasound Technical Information
108
6. The Dynatron 850plus performs the
calculation internally for the “Z”
(impedance value) and the coupling value.
These values are automatically entered and
stored in the Head Parameters for the
device (this operation is automatic and
invisible to the user). Record these values
on the calibration sheet for future
reference.
7. Press the frequency toggle key to select 2
MHz. The 2 MHz LED will light
indicating the soundhead is now ready to
be calibrated at this frequency. Repeat
steps 3 through 5 above.
8. Press the frequency toggle key to select 3 MHz. The 3 MHz LED will light indicating
the soundhead is now ready to be calibrated at this frequency. Repeat steps 3 through 5
above.
9. If you wish to cancel the calibration procedure without storing any new calculations,
press the PAUSE key.
10. This completes the calibration of one soundhead. For devices that use more than one
soundhead, you must calibrate each of those soundheads individually.
To calibrate the next soundhead, turn the machine off, and repeat steps 1 through 10 above.
CAUTION: Avoid unnecessary ultrasound exposure.
