Just Putting a new database together
Usually I don't play with the Integration & Overall Mode override settings.
What should they be and why?
Thanks in advance for any tips and advice

HI Nok,

I don't completely know.  But think it allows the DB to overide the settings in your meter.  Which i am guessing you would prefer as I do.  Means you are all good when swapping instruments or upgrading.   i stand corrected if anyone is happy to provide better advice.

Just remembering. If you are "grouping" then it is essential that you have sensor orientations match.  So when you have a "normal" and a Peakvue grouped together then you MUST have the orientation match.  I also always have the lowest / highest valid signal set to zero which effectively cancels those settings.  Otherwise on dryer cylinderrs amplitudes can be so low tyhat they fall below the limitts and on hammer mills or the like maximiums can be exceeded.  Anyway, just sayin.

I have no preference or should say don't know because haven't researched what the meter settings are to be able to say

So are you saying leave the settings as "None"?

Short answer no. I am well disciplined with my meter settings. So the software settings don't really matter to me but if you are part of a crew and swap meters often then haveing the override at database level is a good thing. Or you can do both. So I guess answer is ... so Integration mode I thhiikkk.. should be set to analogue. Overall mode I... again believe.  But there will be others better versed than me. So here e goes. If you imagine the Fmax of meter than analogue will do an overal to the extent of the meter capability.  Whereas digital just does to the Fmax specified in your setup. .

I leave my settings to none none. But as above. If you want to override then Analogue and digital.  The latter just makes sure that overall matches the overall as per your selected Fmax.

That is how I understand it.  Willing to be corrected by the normal CSI gurus. (And not so normal...LOL

WRT integration:

Analog integration is integration of the TWF, then the FFT process.

Digital integration is the FFT process, then integration.

Analog integration of a signal from an accelerometer will produce a spectrum and a TWF in velocity.

Digital integration will produce a velocity spectrum and an acceleration twf.

With CSI, you would normally use analog integration and collect a special twf in acceleration.

With PeakVue or acceleration, no integration is required so it should stay at none.

I think John pretty well covered the overall settings.

Thanks for the info Vibe & Danny, for now I think I'll leave both as none, unless someone has a compelling argument to change

I've always used analogue mode from MSc days, but recently someone pointed out that digital mode shows impacting in the acceleration TWF better...I think this is discussed on an old forum somewhere...It was something to do with how the TWF was stored as Danny mentioned above?
