Hole-To-Hole Measuring:
Install the two full cone attachments. Close the ProPanel. Use the plus
or minus keys to adjust the display to exactly 38.1mm (1.500 inches).
Place the cones into the holes to be measured. Be sure the cones are
fully seated in the holes. Do not press down on the rail of the ProPanel,
as this may affect accuracy.
Edge-To-Hole Measuring:
Install one full cone attachment and one half cone attachment. Close the
ProPanel. Use the plus or minus keys to adjust the display to exactly
19.05mm (.750 inches). Place the full cone in the hole and the half cone
against the edge of the panel. Keeping the ProPanel rail equidistant
from the panel (by adjusting the half cone's position up or down) will
assure the highest accuracy measurement.
Maintenance:
Occasionally check parallelism of the jaws by measuring a thick piece of
paper on the upper side of the jaws, then on the lower side of the jaws.
A variation of 0.05mm (0.002 inches) is acceptable. Use a precision
square to adjust if necessary. The digital scale should be cleaned of all
debris often. This will prevent premature damage to the scale or
readhead. Should the assembly become difficult to move, check that the
scale is cleaned. Find, and remove any burrs which may have
developed on the aluminum scale. Do not use any liquid lubricants on
the scale assembly, as this may:
1. Impede the readhead's ability to operate properly.
2. Attract other contaminants to the scale.
3. Swell the black bearings on the moving assembly, thus making the
assembly tighter on the scale.
The Digital Display should be cleaned periodically with compressed air to
remove any dust on the lens and keys. All fasteners should be checked
occasionally for tightness. If there is any wear on the green laminate of
the scale, the guide clip pressure on the readhead should be lessened (if
wear continues, the readhead bearing should be replaced.)
