A:
The timers are calibrated in seconds per day. So, the data we show is how far the crystal is off from our standard per day. The nature of the crystals is that they are very consistent. They only limitation would be how long the timer can go for. An example: We cal a timer and it shows -0.5 sec per day. After 3 days it would be -1.5 seconds off. What we are going to show is how off the crystal vibrations are from our standard. The longer the test the greater error. We just report in seconds per day as an easy way to calculate that error.
Most timers are not adjustable.
