Hi John, use gravity. Turn the unit upside down, and see if it makes the error go away. Try all 6 faces.
Maybe you find one where the g-sensitivity of the crystal brings the efc to below 90% again. Easy and non-invasive to do. You may see a couple of ppb change in crystal frequency as you turn the unit over. bye, Said In a message dated 7/10/2011 08:42:15 Pacific Daylight Time, [email protected] writes: > It's possible that the EFC could keep trending downward as the unit > stabilizes, and if that continues to be the direction there should be > no problem.
