US/50 General Operation and Application Procedures
The Ultrasound Transducer
It is important to maintain the transducer. Care should be taken to avoid sharply
bending or twisting the cable. Cable life depends on frequency of use as well as
on proper handling. If it becomes necessary to replace the standard cable, the
transducer and the generator must be returned to the factory.
Damage to the crystal may result from overheating. When not in use, always
return the transducer to the cradle and reduce the Ultrasound Intensity control
to "0".
The transducer incorporates a machined aluminum faceplate and conductance
mediums other than Amrex Conductance and Coupling Gel may cause a
discoloration or "pitting" of the aluminum. Use standard alcohol when cleaning
the faceplate.
Note: Only Use The Transducer(s) Assigned To This Generator. Transducer
serial number is located on the Transducer and on the Generator Label.
Transducer Cable Fault Alarm System
Detects improper transducer cable connection and/or transducer cable damage.
If a transducer cable is improperly connected or damaged, an audible signal will
be emitted from the generator, the "Interrupt On" light will illuminate and the
ultrasound meter will display "0" output. Ultrasound output will cease until the
transducer cable is properly connected to the generator or, if damaged, replaced.
For Amrex models equipped with a standard transducer: The generator and
transducer must be returned to the factory for repair and calibration, electrical
and mechanical safety check.
For Amrex models equipped with the Amrex "QuickConnect System" and less
than one (1) year since the last ultrasound calibration: The transducer cable
may be replaced on site.
For Amrex models equipped with the Amrex "QuickConnect System" and more
than one (1) year since the last ultrasound calibration: Amrex strongly
recommends that the generator and transducer be returned to the factory for
repair and calibration, electrical and mechanical safety check.
