HoW to use for dIrect MeAsure
And As A coMpArAtor
For direct measuring, the micrometer head is set to
zero and the dial indicator is set to zero by the bezel
430XLZ-1 adjustment. Any workpiece within the 1" (25mm)
range can then be measured by the micrometer head
in ten-thousandths of an inch (.0001" or 0.002mm).
The indicator must read zero for each measurement.
If used as a comparator, first set the head and the
indicator to zero as previously explained. Then adjust
the micrometer head to the desired dimension to be
checked. After retracting the anvil, work is placed on
the table between anvil and spindle and the anvil is then
released so anvil and spindle contact the work. Plus
or minus deviation from the nominal work size is then
read from the dial indicator in fifty-millionths of an inch
(.000050") or 0.002mm.
