When do I need the ESU-2050 as compared to the ESU-2300 analyzer?
There are multiple answers to this question and each of them involves the intended use of the analyzer as well as the specific generators under test.
1) If you plan to calibrate your generators, then you should have the ESU-2050. This is because of the 1% of reading accuracy of the ESU-2050 on RF current measurement vs. the 2.5% of reading of the ESU-2300. A 1% of reading accuracy instrument is much better for calibration work. The ESU-2300 is a general analyzer designed to confirm generator outputs as a standard PM type of test.
2) If you have Covidien/Valleylab Ligature or Force Triad generators, many of the procedural steps for field test and/or calibration can only be accomplished with the ESU-2050 because of its extended RF current measurement capability of 7000 ma (7 amps) of RF current. Specific examples include a current peaking test step that requires adjustment of RF current output at 5.5 amps RF. This cannot be accomplished using the ESU-2300
3) If you have generators that have pulsed output waveforms and you want to measure current/power outputs of these generators you will need the ESU-2050. The ESU-2300 does not work with pulsed outputs. Generators that have pulsed output waveforms include the following (the actual list is much longer than below):
- Erbe generators
- Conmed System 5000
- Malis Bipolar Coagulator (Synergetics)
- Stryker generators
- Codman generators (certain models)
4) If you have generators that require measurement of RF current levels less than 30 ma of RF, the ESU-2050 is needed.
