The ornamental design for a documenting processcalibrator, as shown and described.
FIG. 1 is a top, front right side perspective view of a documenting process calibrator showing our new design.
FIG. 2 is a bottom, rear left side perspective view thereof.
FIG. 3 is a front elevation view thereof.
FIG. 4 is a right side elevation view thereof.
FIG. 5 is a top plan view thereof.
FIG. 6 is a rear elevation view thereof.
FIG. 7 is a left side elevation view thereof; and,
FIG. 8 is a bottom plan view thereof.
The broken lines in the figures illustrate portions of the documenting process calibrator that form no part of the claimed design. The stippling in the figures constitutes surface shading that merely clarifies contours of the surface and does not indicate surface texture, material, or color.
