ESU-2300: External Load Capabilities – Built In Non-Obsolescence
The most common shortcoming of any commercially available ESU analyzer is not having the correct load resistor
value available for the specific electrosurgery generator to be tested. No matter how many internal loads are
designed into a conventional ESU analyzer, you can be sure that one of the electrosurgery generator
manufacturers will eventually come along and specify a load that is not in the mix. That’s why we designed
external load resistor capability into our new ESU-2300 analyzer. Not only does the ESU-2300 allow you to
connect an external load, but you have the option of adding this external load value to the internal load selected
(additive mode) or simply using the external load for its actual value (external only mode).
Our ESU-2050 relies on external load resistors, so obsolescence due to unavailability of a specific test load is not
at all possible.
ESU-2000 Series PC Utility Software
Our BC Biomedical ESU-2000 Series Utility Software enhances the use of your BC Biomedical ESU-2050 and
ESU-2300 analyzers. When used with the ESU-2050, the software allows for export of the saved digitized
waveforms from the ESU-2050 to an Excel
®
workbook for further analysis. It also supports remote operation of
the ESU-2050 and ESU-2300. See Appendix M for sample screen shots form the utility software.
One Picture is Worth a Thousand Words – Or Up To 32,768 Data Points
We’ve all heard the old adage that “one picture is worth a thousand words”. The new BC Biomedical ESU-2050
analyzer puts some technological reality to this statement for the first time in ESU testing history. Through
utilization of the ESU-2000 Series PC Utility Software, now you can export data sets to Microsoft Excel
®
, with up
to 32,768 discrete data points on your electrosurgery generator’s output energy waveform. This export function
automatically creates an Excel
®
file that you can name anything you want. No knowledge of Microsoft Excel
®
is
required. The created Excel
®
file will automatically include all of the measurement data as well as a graphical
representation such as the one shown in Figure 19 below. See Appendix K for a sample look at the Excel
®
file
structure.

You can then use the power of Excel
®
to analyze the data in any way you choose. Once you export the data set
to Excel
®
, you can manipulate this data set to accomplish specific tasks, such as zooming in on a single cycle of a
specific waveform. See an example of this capability in the Figure 20 illustration below. This is a user-created
“zoomed” waveform based on the exported data.
