- Page 4 PocketSurf Measurement Parameters Roughness Average—the arithmetic average height of roughness irregularities measured from a mean line within the evaluation length (L). MEAN LINE Maximum Roughness Depth (per DIN) — the largest of the 5 maximum peak-to-valley roughness depths in 5 successive sampling lengths. In the illustration below, R (DIN) = R Mean Roughness Depth (per DIN) —...
- Page 5 PocketSurf Measurement Parameters (continued) Maximum Roughness Depth — For the Evaluation Length equalling one cutoff, it is the vertical distance between the highest peak and the deepest valley within the sampling length. For the Evaluation Length equalling 3 cutoffs, it is the largest of the 3 maximum peak-to-valley roughness depths in 3 successive sampling lengths.

Immediately after pressing and releasing the “Start” button, the readout should display the “Battery” icon and “all 8’s” (full display), indicating satisfactory battery condition for normal operation.
- Page 9 Traverse Length There are three traverse lengths available. For measuring short surfaces such as o-ring grooves, short lands and shoulders use Switch Positions 1 or 3.

- Page 11 Other Probe Positions Other Probe Positions Other Probe Positions Other Probe Positions Other Probe Positions To use the gage in the other probe positions — 90°, 180° or 270°, the PocketSurf unit and probe must be carefully aligned to the workpiece surface to be measured. The base of the PocketSurf unit must be at approximately the same elevation (within ±.100"/±2,5mm) as the surface being measured, and the axis of probe traverse must be parallel to the surface being measured.

Because there is some leeway permitted in the elevation between the base of the Pocket Surf unit and the surface to be measured, the gage can be used to measure surfaces...
