•
reduced manufacturing cost for the test equipment manufacturer
•
shorter product development time
•
reduced accuracy for the end-user
This is why we chose to utilize the industry standard current sensing methodology in our new BC Biomedical
ESU-2050 and ESU-2300 instruments. The manufacturers of these voltage measurement based ESU analyzers
realize the shortcomings of this technology, and simply try to explain around them. The following statement is

for a competitive product that utilizes the voltage measurement technique:
The information above is significant in two main areas. First, the explanation clearly indicates that when using the
device in question,
the operator should expect measurement errors up to 35% (as compared to the industry
standard current sensing technique)!
Secondly, it acknowledges that the
industry accepted normal practice
by electrosurgery generator manufacturers is the superior current sensing technique
.
With the discontinuance of the Fluke Biomedical Model 454A, the BC Biomedical ESU-2050 and ESU-2300 ESU
analyzers are now the only commercially available analyzers on the market today utilizing industry standard
current sensing technology!
Ensuring Quality By Taking Care Of The Details
Sometimes it comes down to the little things that ensure accuracy and a long-lasting life to your ESU analyzer.
Things like selecting the right load resistors and relays that switch in and out individual load resistors in the
internal load bank can make a big difference. The ESU-2300 utilizes switching relays rated at 10,000 volts
(isolation), 3 amps, 7500 volts (switching). The leading competitive “high-end” analyzer on the market utilizes
relays that are rated significantly lower than this. The ESU-2300 utilizes internal precision load resistors that are
rated at 1% tolerance (DC) with a power dissipation rating of 225 watts. The leading competitive “high-end” ESU
