Ultrasound Calibration & Tuning Procedures (Cm Models Only) - Richmar Winner EVO Series Operation Manual

Ultrasound Calibration and
Tuning Procedure
Ultrasound Service Information
Rich-Mar Corporation recommends that all
Rich-Mar ultrasonic therapy products be
returned to the factory or to a servicing Rich-
Mar distributor for service or calibration. It is
recommended that the device be calibrated
annually or when any major component is
changed.
Caution
Calibration and peaking adjustments must not be
attempted unless the person performing these
adjustments has the proper test equipment,
which must include an acceptable ultrasonic
wattmeter, such as the Ohmic UPM-30 or
equivalent. Degassed water must be used to
obtain accurate readings (4 parts per million
of oxygen).
Warning
Use of controls or adjustments or performance
of procedures other than those specified herein
may result in hazardous exposure to ultrasonic
energy.
Calibration and Tuning Procedure
Rich-Mar recommends that the device be
calibrated a minimum of once per year.
10cm²Applicator
You need to complete only the 1 MHz
portion.
5cm²Applicator
You need to complete both the 5cm @ 1
MHz and the 5cm@3 MHz portions.
Hammer Applicator (5cm² & 2cm²)
You need to complete both the 5cm @
1MHz, 5cm @ 3MHz, 2cm @ 1MHz, and
2cm @ 3MHz portions.
Tuning Frequency and Setting Voltage
5cm @ 1MHz
1)
Install the 5cm soundhead into the
wattmeter making sure that only the
face of the transducer is submerged.
Zero the wattmeter.
2) Hold down the Start/Stop switch and
turn on the unit. The software version
should appear on the screen.
3)
Let off the Start/Stop switch and the
frequency will appear on the screen for
5cm@1MHz. Find the frequency peak
and add 5kHz.
Note: Normal range of operation is 930 to 960.
4)
Press Start/Stop switch and the voltage
will appear. Set maximum output to 10
watts.
5cm @ 3MHz
1)
Press the Start/Stop switch.
2)
Find the frequency peak for 5cm
@3MHz and add 7kHz.
Note: Normal range of operation is 3050 to
3150.
3)
Press the Start/Stop switch and the
voltage will appear. Set maximum
output to 10 watts.
2cm @ 1MHz
1) Press the Start/Stop switch.
2)
Find the frequency peak for 2cm @
1MHz and add 5kHz.
Note: Normal range of operation is 950 to 980.
3)
Press the Start/Stop switch and the
voltage will appear. Set maximum
output to 4 watts.
2cm @ 3MHz
1)
Press the Start/Stop switch.
2)
Find the frequency peak for 2cm @
3MHz and add 5kHz.
Note: Normal range of operation is 3050 to
3150.
3)
Press the Start/Stop switch and the
voltage will appear. Set maximum
output to 4 watts.
