With VA tab open, when I select a machine / position (example pump  1 / position 3H) in the navigator pane, the VA tab shows three graphs: an overal trend, the latest spectrum and latest  TWF.

On my computer, if I move my cursor to different points on the trend graph, nothing changes in the spectrum and TWF graphs (they still display the latest spectrum/TFW)

On my co-worker's computer, moving the cursor along the trend graph updates the spectrum and TWF to correspond to the time selected on the trend graph.  (He doesn't recall how he set it up to make that happen).  That's how I want mine to act. 

Question: does anyone know how to the setup required so that the displayed spectrum/twf will update to the selected data point of the trend graph as I move cursor along the trend graph?

Pete,

Sorry, but there doesn't seem to be a way to do that in Vibration Analysis.  AT least in V 5.42 anyway.  You can do it in Plot Data and I can tell you where to find the box to click for that if it will help.

  1. Right-click on the trend plot and select 'Setup Options' from the context menu.
  2. If it's not already open to it, select the 'Trend' tab.
  3. In the 'Display Options' section, check the box next to Update Spectrum/Waveform With Trend Cursor.
  4. Click 'OK'.

Trapper - that's exactly what I was looking for, thanks!!   That is a  much more sensible to look at old data than using the little button on the right side, which doesn’t keep track of where you are on the trend plot.


I spent probably two hours poking around before I posted.   Not in the manual. Not in the options tab / plot jump preferences. Hidden behind a right-click! Arghh. 

As usual, I'm impressed with the help from this forum (and unimpressed with the ease of use of this software)

As I recall it was equally as hard to find in Plot Data the first time.

I'm going through the same thing with the change from Rbmware to SKF after 20 years.

Pete, I don't deserve the credit.

It took me two years to even realize the spectrum/waveforms updated with the trend cursor. Found it by accident when I hit a cursor key while working on a write up. Couldn't figure out why the saved plot didn't include the latest data. [frown]  Like you, it took me hours before I found all the settings about that window.

The manual suxx. It's been that way since 1990 IIRC. I've been thinking of writing a bunch of cheat sheets to explain how to do and set things up in the real world but haven't gotten one of these yet:

Ha!  Yeah, I've heard about that round tuit. Let me know when you get one!

Danny if you need any Help I will try my best I did a lot of tweaking of my Aptitude graphs for the last few months.

Pete, I was having a similar issue displaying updates to graphs on multi-screen display. 

The problem with a lot of these software programs is their legacy...they are new-ish stuff built on old stuff and over time the old irrelevant stuff doesn't get trimmed away and they become very bloated. Akin to Building shiny new houses on old crumbly foundations.

Hi MarkL, would be really happy to hear from you regarding recent use of Aptitude.. Which I affectionately called Craptitude and microDog when I worked for SKF. (Being a CSI user and company bought out by SKF)
Anyway that is another story.

So please tell me that the "X" function has been implemented and MPM-> rpm ratio or similar. And Global speed set.

The one thing that perplexed me. Is that the big companies are arrogant.  And they do NOT do their market research.  So why would you not have a bit of a look at opposition to see what they are doing? mmmmm

When I became SKF their answer to doing paper machines was. Just tacho every roll. I poo you not. And my reply was that is not practical. Response.  oh well never mind. 

How can a company not see at least what others have done in the past. 

It was an eye opener and why I would NEVER go anywhere other than CSI

Hey Pete / MarkL, I get what you mean. I truly do.

Then again, the new comers come a long and reinvent the wheel adamant that they know a better version.  Now I am not one to diss reinventing but am pretty sure the wheel is not supposed to be redesigned. My thinking is that there are certain things best left alone. Anyway, I a sure the board will throw up some arguments against my thinking. I am still at a loss as to why skf did not have certain functionality built in when CSI had that more than 25 years a go. Idiots.

SKF had more functionality, in the DOS version, for every new totally rebuilt win version there is a loss of functionality, is it 3-4 times now? Minimum addition of new things....

Hi Vibe, I am sure I have answered your question on the 'X' button on a few occasions here but again, yes they have 'x' set up as a diagnostic cursor which lists the peaks of interest and ties them to an activity index according to theyre activity in the spectra.
I don't work on paper machines so no need to Mpm readings but they have calculation ratios which can be set up in the fault frequencies etc. 

I'm using aptitude about 8 years now and theyre have been a few improvements from the earlier versions I used. 
It's not perfect but working for me so far so good. If I had one gripe it would be nice to have a decent setup wizard as I find database set up a bit tiresome.

MarkL,

Thanks for the kind offer. You have helped us immensely in the recent past and I think we have things under control but are constantly learning new stuff.  Vibration Analysis software is like chain restaurants.  They all do some things very well and other things not so well.

I think the thing I miss most from CSI is RBMWizard.  If properly controlled, the Wizard was the best way to build a database. If gone about straight by the instructions, you might not get the desired results.  But for setting up gearboxes, it's the best. Just enter the gear tooth counts and the bearing numbers and it will do all the rest. Watch what AP and AL sets it assigns, though.  I wish we had something like that in SKF.

But collect some data on the wrong machine with CSI and you may as well just throw it away. Trying to move it is practically impossible. It always finds something that makes it create new MP's when you try to move it.  With SKF, it's just a value in a row and a column.  You can just move it to the proper row and column.

We're struggling with how to manage variable speed equipment a bit though.  With CSI, you can set it so that you can check the speed at one point and it will adjust all the other shaft speeds accordingly. If the equipment is set up as variable speed, the data collector prompts you to enter the speed in one of a variety of selectable ways. That doesn't seem to be the case with SKF and I don't think we have a really good grasp of how that should be managed.  If you've got any ideas, maybe it would be best if you send me a PM or I could start another thread.

Hi Danny, you can add a manual input speed point and then attach a speed tag to it (including ratios in the case of gears) and when you go to collect a reading it won't let you take data until you enter the speed then the inputted speed reference will affect all the speed tagged points on the machine.

If I am missing something in what you are asking my apologies but That is how I set up speed input on variable speed machines.


On being able to move data on mistakenly taken readings yes I did it loads of times at the start thankfully not so much nowadays. But thankfully it can be dragged and dropped across. 
Regards.
Mark.
