Achieve fast repeatability and reproduceability between operators by utilizing t wo TF-1F and two TF-SV MIC TRAC™ fixtures for setting ball mics and certain indicator style gages.

Set the MIC TRAC to the desired setting distance and adjust the gage accordingly. Properly install a TF-SV on each TF-1F. Then, set the gage’s contact points into the proper grooves. Finally, zero the gage.


For maximum accuracy, use one TF-SV as a fixed pivot (keep the contact point seated in the groove) and sweep the other point against the face of a TF-1F block. This provides outstanding stability on a range of sweeping motions to locate the “null” point. Once located, you can zero the gage. Experienced machinists prefer and stand behind this method every day.
