xcell 0524 tachometer
Does anybody have one of these tachs? if so, how many blades should be visable when taching a 3 blade system? my instructions say 6 blades, is this correct? or should it be 3 blades?

Ken,

I know with a 2 blades system when you have the right RPM the blades stop spinning in the view window. So with this you would see 2 blades. With a 3 bladed head I would guess you should see three.

Tacho'ing a multi blade head with X-cell 0524
It is very simple, all you have to do with any number of blades is to get the blades to look stationary through the Tacho viewer
Divide the resulting tacho rev's, by the number of blades being tacho'd, and multiply by 2

The reason for this method is that the shutter in the tacho is geared for 2 blades only

Please accept that this method works, I have been using that type of tacho since they first came out, and the tacho before that

Do not listen to the theorist, just do it

Which 0524 tacho
I suppose I should have asked which colour Tacho you have
Red 500-3000 rpm range
Blue 1000-1990 rpm range
Both are coded 0524

What head speed
What head speed will you be running at?
If more than 1000rpm, then no problem
