It is good practice to quickly verify repeatability on a MIC TRAC™ 3000 at frequent intervals between calibration periods.
This simple verification process involves zeroing the MIC TRAC using TF-1F fixtures (anvils). This procedure will ensure the unit repeats to a resolution of 0.0001″ or better.
Simply use the Coarse Adjust Knob to open and close the anvils a short distance and check that they show .00000″ when brought back together. Do this at least three times with consistent force* to confirm you are repeating .00000″. Finally, move the carrier all the way to the end of track and bring it back to zero. If it repeats, you should be good to go!
*This is more easily achieved with the Force-Lok™ option added to an MT-3000.
