Excellent explanation, could you provide the spreadsheet. And on the other hand you will be able to explain the principle of compatibility and interchangeability between the different sensors, signal conditioners and extension cables.
Hi Jim. Truly an avid fan of your work! Just wanted to confirm on the core resistance criteria on your spreadsheet as I am creating my own. I believe that the lower range should be 0.84 and 1.14 from the 0.99+/-0.15 right?
The easiest way is to figure out how much resistance per meter should be offered by each conductor. This information will be available in the manual. For the 3300 the core should produce .22/meter and the jacket .0667/meter. The problem is, most basic meters will round up to a tenth ohm. When you build your pass fail condition you have to account for that. I have a video of how to build this spread sheet, I could upload it if you want.
Why do you have CORE RESISTANCE lower-0.84 and upper - 1.14 in the begining video. And then CORE RESISTANCE lower- 0.8 and upper - 1.2 in end of the video?))
The only way to get an accurate measurement of resistance this low, is to use an instrument with a 4-way bridge. Since most basic multi-meters are two wire measurements and round up to the tenth ohm, the accuracy isn't sufficient for this type of measurement. Even when you use the delta button on your meter to eliminate the test lead resistance, a .1 ohm resistance float can exist since the resistance value is changing constantly. To avoid false failure indications, I open the tolerance a little bit. This problem is less of an issue if you stick to measuring the entire circuit resistance (core, jacket, & probe). If you have a precision ohm meter, this will not be a problem.
The negative voltage is used by Bently Nevada because of the design of their proximitor. During the initial design, the cost of one transistor over the other was a consideration and they went with negative bias voltage due to the availability of PNP transistors. That is the answer I got years ago when I asked the same question.
I am working on a series of videos that explain how to quickly make your own spreadsheets. A skill that will come in handy for many other test procedures.
Thank you sir....god bless you....keep posting knowledge.....i really appreciate your hardwork...
Great explanation, very informative
Thanks SIr
Thank you so much for this video, sir.
Welcome!
Greate information in this video. Is there a link somewhere that I can download your Resistance Check Spreadsheet?
Gracias, excelente explicación.
thanks for this video is an excellent explanation
Glad you liked it. Thanks for the compliment.

Thank you for the feedback. I will.
@@jimdiggins101 hi! can you upload this one? thanks!
Thank you so much
can i use 8 mm probe to measure radial vibration of a 27 mm nickel alloy shaft?
The previous video on "coax testing" had a bogus copywrite flag, so I replaced it.
superb video, thank you... where can we download the test sheets and other for reference

Excellent Explaination.... From Where I can download this test sheet??
Hello buddy, can you provide this spreadsheet?
Hello, this is useful video. How can I get this test sheet?
I uploaded a video on my channel showing how to make a an excel form. I can also email you a similar form to the one in this video.
@@jimdiggins101 hi..can u give to me he table format.. tqsm... abdulrahmansofian8@gmail.com
@@jimdiggins101 Can you email to me, similar form to this video?
@@jimdiggins101 Hi Jim. How are you?. Can you email to me, with the excel form?
Sorry but I dont distribute this spreadsheet. I will upload a video showing how to build one when I get time.

@@jimdiggins101 Thanks for the answer. Where can I download your test tables?
I do not have tables available for download. I can make a video showing how to create a table if you like.
@@jimdiggins101 it will be great.Thank you
What is tha input and output radial axial vibration plz answer
I am not sure what you are asking. Can you provide some context?
Hi. Where could I get your excel table ? I would like to get it
Build it in excel. I show all the necessary formulas in one of my videos.
Thank you Sr. I'll do it
Why -vtg is used insted of +ve for proximity probe

This tape; is the 3M scotch 70 ?
Yes. Use Scotch70. You can also install a boot. Here is a UA-cam video on installing a boot ua-cam.com/video/0qTd8aeoOGY/v-deo.html.
where can I get the test sheets?
I need the chart
