  1. The ornamental design for an ergonomic pressure calibration pump, as shown and described.

This pump incorporates easy to use handles, a vernier knob to adjust pressure, and inside the vernier knob is the pressure relief valve which relives the pressure created. The created pressure, is used in conjunction with a sensor to be tested, and a pressure calibrator. The reservoir is a shatterproof, transparent, tapered container which makes viewing the liquid used for pressurization easier to see.

FIG. 1 is a front elevational view of an ergonomic hydraulic pressure calibration pump showing my new design.
