•
Utilize external high-accuracy current sensing transformers of 0.1:1 and 1:1 ratio (typically Pearson
Electronics Model 411 and 4100 transformers), thus eliminating the virtual inaccuracies of commercially
available analyzers that utilize voltage measurement techniques
•
Eliminate internal test load switching relays that add capacitive leakage at RF frequencies and decrease
the overall level of instrument accuracy
•
Add the ability to capture and store in high resolution, the ESU output waveform
•
Supply Crest Factor (CF) capability well in excess of the current industry (competitive instrument)
limitation of 16
•
Make the new instrument much smaller and lighter, and more resistant to breakage during shipment than
the current industry available ESU analyzers
•
In summary, give us an instrument that we can use to test the way we have tested our electrosurgery
generators over the past 10+ years!
The result of these ongoing collaborative efforts over the past 18 months is the new BC Biomedical ESU-2050
analyzer, with never before seen levels of accuracy and functionality in a commercially available ESU analyzer

.
Testing with the new ESU-2050 analyzer is remarkable easy, and requires minimal setup, as can be seen in
Figure 13 below.
