Belt tightness meter instead of sound frequency

Anyone know what belt tightness is needed using a meter like this?

Prusa goes by the sound frequency of strumming the belt like an instrument.

Many of us use this:

- also good for Mk4.

I've used the gauge linked to by diem for years, on Mk3, Mk4 and Minis. I found it more reliable than anything else.

I cannot see this gauge (gage) working on 3D printers that have an extruded rail guide system, as the belt runs inside under the "V"

With these belts being enclosed it´s difficult to use the Prusa trusted technique of audibly giving the belt a "twang" and getting 

the right note. IE then we have the correct tension or maybe the use of a music tuning device would be more beneficial.

Free aps are available through any tablet or phone. What note do we tune to?
