Esu-2050: Truly Unique In The Market - BC Biomedical ESU-2000 Series Guide Manual

The release of the new BC Biomedical ESU-2000 Series, including the ESU-2050 and ESU-2300 analyzers
represents a paradigm shift in the level of technology offered for electrosurgery generator testing.
The new ESU-2050 is a direct result of extensive collaboration with leading medical device industry
electrosurgery generator manufacturers. The ESU-2050 analyzer was designed to be 100% compatible with the
following mandates of some of the leading manufacturers in this area:
•
Accuracy of 1% (give us a calibration quality instrument that can replace the legacy Fluke Electronics
7
Model 8920A Digital Wide-Band True RMS Voltmeters currently in widespread use)
•
Utilize external high-precision (1%) power resistors widely used in the OEM segment
7
The Fluke 8920A was discontinued at the end of 1999 due to "product maturity" and electronic component shortages. For the detailed statement on
product discontinuance from Fluke Electronics, simply visit the following url: http://us.fluke.com/usen/support/safetynote/DiscontinuedProductNotice.htm.
Fluke Biomedical / Metron QA-ES: The re-branded Metron (Trondheim, Norway) QA-ES is
the current "high-end" ESU analyzer offering from Fluke Biomedical, effective March 18,
2007. Originally introduced by Metron AS in Trondheim, Norway, the QA-ES offers accuracy
of 2% of reading for RMS current measurements. RMS power reading accuracy is not
specified by the manufacturer. The QA-ES does not utilize industry standard current sensing
technology. See Appendix D for specifications on the Metron QA-ES version of this analyzer.
Fluke Biomedical instrument specifications can be found on the manufacturer's web site.
BC Biomedical ESU-2050: With commercial availability scheduled for July/August 2007, the
new BC Biomedical ESU-2050 represents a paradigm shift in ESU analyzer technology,
allowing customers to test their electrosurgical generators in exactly the same way as the
electrosurgery manufacturers do! With unprecedented 1% of reading accuracy, the ESU-
2050 is the most accurate ESU analyzer on the market, offering advanced level features and
functionality such as exporting waveform data sets with up to 32,768 data points to Microsoft
®
Excel for graphing and analysis. Patent pending DFA
BC Biomedical ESU-2300: With commercial availability scheduled for July/August 2007, the
new BC Biomedical ESU-2300 is a conventional design "mid-range" ESU analyzer utilizing
internal precision load resistors. Unlike other mid-range analyzers on the market, the ESU-
2300 utilizes industry standard current sensing technology for improved accuracy and
reliability. Like the ESU-2050, the ESU-2300 utilizes patent pending DFA
ESU-2300 offers the ability to connect an external load resistor, thus ensuring the availability
of the required test load no matter what the value is. External load resistors can be used in
additive mode (add the external load resistor value to any of the internal load values) or
external only mode (use only the value of the external load resistor).

ESU-2050: Truly Unique in the Market

From its original product design proposal, the new BC Biomedical ESU-
2050 analyzer has been a totally different instrument as compared to the
traditional approach to ESU testing. Until now, traditional ESU analyzers
have had the following common elements:
•
Internal load resistors (typically the most fragile element of the
conventional ESU analyzer)
•
Accuracy on RMS power typically in the 5% to 10% range
•
Accuracy on RMS current typically in the 2% to 5% range
•
Crest factor (the ratio of V
16 or less
•
