Thank you very much for the information, although I have a question, at minute 2:24 you put the value of 1 in the voltage column. why 1? What shouldn't be 10mil*200mV= 2V?
Dear Jim thanks for video, I only have two questions, at the end we obtained values that were out of tolerance, right? And this was probably because we use other extension cable model, right? In advance thanks for your response! And good job!! 🤘

hello, when i connect the power supply 24VDC positive to the com and negative to the Vt(-24 VDC) it creates an alarm on the power supply and shut down the power supply. Please advice on wiring?
Sorry, I can't. That is why i uploaded a video showing how to make in excel. Follow along and you should be able to make one for yourself. If you run into problems let me know.
I no longer have that spreadsheet to check. I believe each value represented the deviation from the expected value for the associated test point in relation to the linear span of the uncontrolled variable. In addition I think I performed a best fit using the "least squares" method (=LINEST) for the collected data, then compared that array with the stated manufacturer's and flagged a fault using conditional formatting if the difference exceeded the stated tolerance.

I run two deviations simultaneously. One is a total slope deviation and one is a deviation in scaling factor. The most important one is the scaling factor deviation. For that one, you calculate the voltage difference (D) between test interval (A) and (B) (A-B=D). Then determine the deviation from the rated ISF for the given test point(ISFD), (D-ISF=ISFD). That difference is then divided by the rated ISF. The formula to this point is ((A-B)-ISF)/ISF=X percentage of deviation. Here is an example using a 200mV/mil (2volt/10mil) product with the following test interval..20mil=3.1Volts and 30mil=5.2Volts. (5.2-3.1)-2=0.1 0.1/2.0=0.05(5%deviation). The percentage of deviation on the total slope runout is performed by building a linear slope and comparing each individual test point to the shared location in the slope. As an example: An ISF of 2V/10mil starting with 1V@10mil would create a projected value of 9volts at 50mils. Your actual measured value at the 50mil test point can be compared to 9volts to create a percentage of slope change. This deviation value is not as important in vibration because the distance between the shaft and probe is not as important as the continuous change in voltage between the shaft and the probe. It is complicated to put in typing, hope it helps.

Hi Jim, great video. Is the spreadsheet something you can send over email if i provide you an email address. I understand you have made a video to show how to generate one of ourselves but would appreciate if i can get this off you.
Thank you for the clear and concise explanation. I'm looking forward to your next Bently Nevada video.
Thanks for watching. I am working on an axial thrust installation video.
Thanks for your explanation and clear information
You are welcome
Thank you for excellent recearch.
Glad it was helpful!
Good exlonation jim,thanks.
Hi,
Great video 👍🏻👍🏻.. I have a doubt.
How to calculate ISF %error manually ? Please share the formula.
Thank you 😊
@@Somethingspecial897 the LINEST function in excel is good for calculating a deviation from straight line for a set of data points.
Thank you very much for the information, although I have a question, at minute 2:24 you put the value of 1 in the voltage column. why 1? What shouldn't be 10mil*200mV= 2V?
The response rate of 200mV / mil is only valid within the range of linearity. 0-10 mils is outside this range.

Correct. Incorrect length is the most common cause of error
Hi this was a very good presentation
I request if you could explain how the graph could be configured
I can do that.
What do you supply proximity power with? What kind of lines?
Are you willing to share your spreadsheet?
Thank you very much

Power to com and -24. Output signal to out.
if ISF% bigger than the manufacturer's standard, how recalibrate?
WOULD YOU LIKE TO SEND THE TALEBA FOR SENSOR CALIBRATION
Thank you!
Welcome!
How much is this kit?
@Jim Diggins Hi brother..Could you pls share a copy of the excel sheet if you dont mind. Will be really helpful..
Sorry, I can't. That is why i uploaded a video showing how to make in excel. Follow along and you should be able to make one for yourself. If you run into problems let me know.
i can sent it to you, if you send me your email

The test of linearity check is for proximetor or for the probe !?
Probe, cable and proximitor. If you leave it connected to the card, it will also verify the monitoring rack and associated wiring.

hello, How did you determine the standard deviation in the table below the graph?
