Calibration Procedure
With the exception of calibration, all service on the Dynatron 150plus device should be
performed by a Dynatronics service technician. If your Dynatron 150plus requires
service, contact Dynatronics Customer Service at (800) 874-6251. The calibration
procedure MUST be performed by a qualified Ultrasound technician using the
proper equipment. Calibration may be performed either by Dynatronics or by an
Ultrasound technician in your local area.
When to Calibrate: Dynatronics recommends that the Dynatron 150plus be calibrated
annually to ensure the unit is working at its peak performance.
What to Calibrate: You must calibrate all soundheads used for this device at all
three frequencies (1, 2, and 3 MHz).
Equipment Required: You will require an Ultrasound power meter capable of
accurately measuring outputs up to 3 MHz. Check the manufacturer’s specifications
to confirm your power meter meets this qualification. Ohmic Instrument UPM-DT1 or
UPM-DT-10 are recommended for use.
Water Quality: Water used in the testing procedure must be degassed water with an
oxygen content of four parts per million (4ppm) or less.
The following steps are provided to assist the technician with the calibration procedure.
A calibration program is built into the software for the device. The procedure utilizes
keys and displays on the key pad that are normally used for other purposes, but which
have specialized applications in the Calibration Mode.
If you have any questions about the following instructions, contact Dynatronics’
Customer Service Department before proceeding.
STEPS
1. Begin with the machine turned off. Plug the soundhead to be calibrated into the
Dynatron 150plus Ultrasound output jack and center the soundhead over the cone in
the Ultrasound power meter.
2. Enter the Dynatron 150plus’s Calibration Mode by pressing and holding the
PAUSE key while turning the machine on. The display windows first show the
soundhead type that is plugged into the machine (see Soundhead Type Table on
next page).
