I have just bought a SoundLab Tuner G027FA for the wife's violin.

This seems to be fine for Equal Temperament tuning but I can't figure how to get it to change the reference settings for Just Intonation.

Violin string tuning to play with:

Scottish Small Pipes (A=440 Hz) Northumbrian Small Pipes (F=353.38 Hz)
   4G    198   Hz                           176.69 Hz
   3D    293.33Hz                         294.48 Hz
   2A    440   Hz                           441.73 Hz
   1E    660   Hz                           662.59 Hz

There doesn't appear any easy way of storing these reference frequencies for quick tuning changes.

Any suggestions on how to resolve the problem?
