INTRODUCTION
The Model RF301B
is designed to measure the power output of
electrosurgery units. The instrument is accurate and simple to
operate. Test data can be used for calibration,:quality
assurance diagnosis and reference for establishing trends in the
operating performance of electrosurgery units.
1.1
Application
The Model RF301B
can be used by technical and non-technical
personnel to test all electrosurgery units. The proper operation
of an electrosurgery unit and calibration are easily accomplished
using the Model RF301B.
The power output can be recorded for each
setting of the electrosurgery unit on the RF3R
tag and attached to
the front panel so that personnel using the electrosurgery unit
can depend on the consistancy of the power output.
The Model RF301B
can be used by professional people in the
operating room or by engineering and maintenance people during
routine inspections. It is portable and easily transported from
facility to facility. The rugged case makes the Model RF301B
ideal for field service work.
1.2
Establishing Test Criteria
The acceptable output and standard for performance should include
the manufacturer's specifications with respect to power output at
a specified load a nnddaa specified frequency. The manufacturer's
specifications are bench marks to use in establ1shing acceptable
performances.
Safety standards should be established for electrosurgery units as
well as all other devices used in the hospital. (See electrical
Safety Prograro Guide; contact the factory.)
