1edf
1 equal division of the perfect fifth (abbreviated 1edf or 1ed3/2) is a nonoctave tuning system that uses equal steps of 3/2 (one perfect fifth), or about 702 ¢.
Theory
One note repeated in just perfect fifths is an example of a trivial temperament. 1edf can be viewed as the circle of fifths or Pythagorean tuning without octave reduction.
The adjacent open strings of a violin, viola or cello are traditionally tuned in perfect fifths. These instruments are hence tuned in 1edf.
