Hi Akemi

I calibrate it weekly. And also document each calibration as you know with the muscle panels especially for the ATP's they have to be accurate.

Hi Akemi,
     I calibrate every other day that it is in use (Mon, Wed, Fri). I would
do it more often if it were required. As it is there is very little drift
from day to day. I have noticed more drift if I don't use it one day and it
goes to day three. If I'm making something up that I know to be extremely
finicky I calibrate it again just for good measure. Honestly calibration
should be so routine that it is almost automatic.
