Warranty

Netech warrants the UPM 2000 against defects in materials and workmanship for one
year from the date of original purchase. The standard warranty is extended for a second
year if the instrument is returned to Netech for its recommended yearly recalibration.
During the warranty period, we will repair or, at our option, replace at no charge a
product that proves to be defective, provided you return the product shipping prepaid to
Netech Corporation. Only serialized products are covered under this warranty.
This warranty does not apply if the product has been damaged by accident or misuse or as
the result of service or modification by other than Netech Corporation, or if its serial
number is defaced or removed.
Netech reserves the right to discontinue the UPM 2000 at any time, and change its
specifications, price, or design without notice and without incurring any obligation.
Netech guarantees availability of service parts for 5 years after the manufacture of the
unit is discontinued.
The warranty is void if you elect to have the unit serviced and/or calibrated by someone
other than Netech Corporation.
The warranty covering your product becomes void when the tamper-resistant
Quality Seal is removed or broken without proper factory authorization.
We strongly recommend, therefore, that you send your instrument to Netech Corporation
for factory service and calibration, especially during the original warranty period.
The purchaser assumes all liability for any damages or bodily injury, which may result
from the use or misuse of the unit by the purchaser, his employees, agents, or customers.
Warranty may be void if shipping procedures are not adhered to.
In no event shall Netech Corporation be liable for consequential damages

Hazard Warnings
∗ Warning! Power Rating. The UPM 2000’s mains power input must be connected
to an external power transformer that provides voltage and current within the
specified rating for the system.
Use of an incompatible power transformer may produce electrical shock and
fire hazards. See Specifications and Optional Accessories in Chapter 2.
∗ Warning! Internal Voltage. Always turn off the power switch and unplug the
power cord before cleaning the UPM 2000’s outer surface.
∗ Warning! Liquids. Avoid spilling liquids on the analyzer; fluid seepage into
internal components creates a potential shock hazard. Do not operate the
instrument if internal components are exposed to fluid.
Precautions
The following precautions are provided to help you avoid damaging the system:
∗ Caution: Service. Authorized service personnel should service the UPM 2000.
Only qualified technical personnel should perform troubleshooting and service
procedures on internal components.
∗ Caution: Environmental Conditions. Do not expose the system to temperature
extremes. Ambient temperatures should remain between 10-30°C operating or
5-40°C storage. System performance may be adversely affected if temperatures
fluctuate above or below this range.
∗ Caution: Do Not Immerse. Clean only with a mild detergent, and wipe down
with a gentle cloth.

Summary of Features
Netech’s UPM 2000 digital ultrasound power meter provides an accurate means of
verifying and calibrating the output of therapeutic ultrasound devices. The
instrument measures output through a strain gauge bridge transducer.
After the initial output is verified, the UPM 2000 is used to accurately calibrate the
ultrasound unit under test.
In addition, the UPM 2000:
• Has a resolution of 0.1 W and a repeatability of ±-3% of
readings ±.2 watts from 0 - 30 W;
• Maintains electrical accuracy of .01 grams throughout
range;
• Features a large, backlit, easy to read display that enables
the user to quickly and accurately make power
measurements;
• Can accommodate a variety of transducer shapes and sizes
without interfering with the measurement;
• Has a drain hose and stopper for convenient and
controlled drainage of the tank.
• Has a built in draft shield for improved stability in
readings.
• Measures total-pulsed or continuous-average power.
• Has a selectable readout in grams or watts.
• Can be battery operated or line-powered 120 VAC for
long-term sessions.
• Has an RS232 interface.
• Has a field calibration check.
• Is housed in a sturdy Kydex®case.
• Is portable to meet the needs of service groups and
biomedical engineers.
• Comes with a soft carrying case as a standard accessory for
ease of transporting and storage.

Ultrasound and Its Applications
Human perception of sound waves is limited to frequencies of fewer than 20,000
vibrations per second. Higher frequency vibrations — between 0.7 and 3.3 MHz —
are used for ultrasound therapy. (Most ultrasound equipment produces an output of
between 1 and 3.3 MHz.)
An ultrasound unit produces electrical oscillations at a specified frequency that cause
the transducer in the ultrasound applicator to generate sound waves. The resulting
ultrasonic radiation is transmitted from the ultrasound applicator, or treatment head,
through a coupling medium, to the patient’s tissue.
Therapeutic Use of Ultrasound
The therapeutic use of ultrasonic energy is accepted worldwide, and most
modern hospitals and clinics have ultrasound devices in their physical therapy
departments.
Ultrasound therapy is primarily used in the treatment of sports-related injuries.
Another common use is the treatment of circulatory disorders and rheumatic
diseases of the musculoskeletal system and peripheral nerves. Ultrasound has
been found to be extremely effective in treating body areas with a great deal of
scar tissue.
Physiological Effects of Ultrasound Therapy
It is well documented that ultrasound therapy heals because of thermal,
mechanical, and chemical effects. *
Thermal effects include deep tissue heating at depths to 5 cm or more. The thermal
effects of ultrasound differ from diathermy (the use of electrical impulses to
produce generalized vasodilation) in that the ultrasound beam heats only a small
tissue area that approximates the cross-section of the beam. This heating effect is
concentrated in muscles, ligaments, nerves, bones, and where the ultrasound
beam crosses from one type of tissue to another.
The mechanical effects are best described as micro massage, a deep stirring action
within the tissue. The benefit of this action is an increased circulation to the
damaged tissue. In addition, ultrasound is capable of separating collagen fibers
from one another and of changing the tensile strength of tendons, thereby
increasing their extensibility.

The physiological benefits from ultrasound therapy are numerous. Ultrasound
therapy affects the peripheral nerves by chemically changing the conduction
velocity (this has been shown clinically in situ). Ultrasound alters the diffusion of
Na+ and K+ (sodium and potassium) across red blood cell membranes.
Ultrasound can also remove some salt deposits from irritated tissues.
* Physical Agents for Physical Therapists, Second Edition, James E. Griffin and Terence Karselis, Charles C. Thomas
Publishing Co., 1992.
Patient Treatment with Therapeutic Ultrasound
The clinician working with ultrasound can ensure successful ultrasound treatment by
assessing:
λthe physical condition of the patient,
λthe absorption coefficient of the tissue(s),
λthe energy output of the ultrasound unit (continuous and pulsed),
λthe massivity and location of the affected tissue, and
λthe spread pattern of the beam.
The most essential assurance that the clinician can have is the verification that the
ultrasound unit is producing the ultrasound energy for which it was designed. The
Netech UPM 2000 digital power meter enables the clinician to accurately measure this
output energy.
