BMET Basics: How to test an Electrosurgical Generator (ESU) - Generator Output Test with QA-ES III

[@BetterBiomedChannel]

Because of the poor documentation included with the Fluke, this video helped us figure out the Fluke ports used in testing. Thanks.

[@HTMWorkshop]

Glad it helped! Yes for some reason they skip over a lot in their documentation.

​@@jacekc6179 well I guess they are worried the ESU mfg will get mad at them about something - thanks for the info

[@ariffmba]

Really this video is very useful and information and easy to understand and demonstrate , thank you

[@HTMWorkshop]

Glad it was helpful!

How would you test the electrical safety test? meauring the lekage in patient applies parts? the device must be run with CF class.

[@HTMWorkshop]

I don't have a video specifically on the full electrical safety test - but I do have one on high frequency leakage kzbin.info/www/bejne/jIbFmWqwgqioaqc and REM testing kzbin.info/www/bejne/qabPh3Rne5yao5Y

Excellent!!!!

Some common brands of ESU: Bovie (the "de facto" brand) Aesculap/B. Braun Pfizer-Valleylab/Covidien Wolf Karl Storz

[@Kennerdoll]

How do you tell that the ESU is operating well with those tests?

[@HTMWorkshop]

Are you asking how you know the tests are in spec? Each ESU typically has a range the power output tests should fall within usually around plus or minus 5% but can be different for the lowest settings. The ESU service manual should give you an idea on what the correct output range is for each power setting.

How do we connect the Bipolar utilizing the Same analyzer for KLS MARTIN Maxium 402? the connection of Monopolar done perfectly

[@HTMWorkshop]

I can't say I have used that model of ESU before - but I do have some updated videos that may help - I go into more detail on the concepts which may help you work through your particuliar ESU kzbin.info/www/bejne/fYeZZ6ukjcZ4pq8 kzbin.info/www/bejne/qabPh3Rne5yao5Y

Hi! How does one do the bipolar output connections for this unit?

[@HTMWorkshop]

Hi, I unfortunately don't have a video on that yet but If my memory serves me the main change is moving the connections over to the bipolar ports, we do have some more videos on ESU's - kzbin.info/www/bejne/fYeZZ6ukjcZ4pq8

[@ariffmba]

how to test the bipolar option with the Fluke ESU through bipolar forceps, can you help

[@HTMWorkshop]

Not yet, I need to get some forceps so that I can show that first.

[@ricardocarrillo4772]

Sorry Mr can you tell me wich are the tolerances of variability in cut a coag test?

[@HTMWorkshop]

Hi Ricardo, it depends on what device you are testing and which test you are running. Can you be more specific on what you are looking for.

[@StefComplex137]

Great Video. I am looking into testing an ESU that uses square waves alongside a standard unit such as a bovie. Could that be possible with this device and is the information this device provides similar to an oscilloscope measurement?

[@HTMWorkshop]

If you are looking to measure current or voltage out I can't remember if the fluke analyzer has an output function for that - I know for sure you can measure power output and then send that info to a spreadsheet and graph it - but I do not remember a graph function on the device itself - I'll try to check it next time I stop by. You can probably (but I have not tried) use an oscope - if you set up a little test jig (maybe a 10 kohm high wattage resistor for the load) and then measure the voltage output with the scope (you need to be careful to protect the scope but I think that should work). You want to make sure all the current goes through the test load (and not the scope obviously)

[@StefComplex137]

@@HTMWorkshop I noticed that this device in the manual states that the crest factor measurement ranges from 1.4 to 16.0. A square wave will have a crest factor of 1 so will this affect the other measurements/cause issues?

[@StefComplex137]

@@HTMWorkshop also wondering if the data saved from this device is just one measurement or consists of numerous data points for each current, voltage, ect.

[@HTMWorkshop]

@@StefComplex137 The only measurements I have used it for our power measurements. So it is doing the calculation for you - I am not sure if the crest factor will be an issue - definitely an interesting question. I am pretty sure there is an oscilloscope output in the back of the unit you can use if needed.

Brand and model of ESU and its operating frequency needed to determine.
