*1 The negative pressure type displays positive values when negative pressure is detected and displays negative values when positive pressure is detected. (Example: When -50.0 kPa is detected, 50.0 kPa is displayed.)
*2 According to the Measurement Act, we are changing to types that only display units of Pa.
*3 The unit can be selected from MPa, kgf/cm2, mmHg, Psi, and bar.
