Zeroing the RG-7000 Gage Using the MIC TRAC (continued)
17. While maintaining pressure between the lower
thread roll and flat face anvil, sweep the upper
thread roll up and down to locate the smallest
indicator reading.
18. Turn the indicator dial on the RG-7000 to align
the needle with zero.
19. Tighten the indicator clamp.
20. Press the retraction lever and remove the RG-
7000 from the MT-3000. Reposition the gage
on the flat face anvils to verify the zero setting.
Note:
Note the position of the small revolution
counter on the indicator before removing
the gage. Place a piece of masking tape on
the backside of the indicator and record the
dial setting of the small revolution counter
to eliminate incorrect indicator readings.
