PRESSURE DISPLAY APPARATUS

PROBLEM TO BE SOLVED: To improve the versatility and flexibility by avoiding a trouble where a zero reset function is substantially disabled or its use is restricted, and to further improve the benefit and convenience in use. SOLUTION: A pressure display apparatus 1 includes a detected signal processing mean 3 for processing a detected signal Si obtained from a pressure detection means 2 for detecting a pressure P, a pressure value display means 4 for displaying on a display 5 a pressure value (detected pressure value Pd) regarding the pressure P at least based on the processed signal Dd obtained from the detected signal processing means 3, and a reference point adjustment means 6 for adjusting the display on the display 5 for a given reference pressure value Ps. The reference point adjusting means 6 has a reference pressure value setting function 6a for setting the reference pressure value Ps for a given magnitude, a deviation value setting function 6b for obtaining and setting a detected pressure value Pd corresponding to the reference pressure value Ps and the deviation value Ed of the reference pressure value Ps, and a correction function 6c for correcting at least the detected pressure value Pd regarding the pressure P and displayed on the display 5 based on the deviation Ed.
