Pressure Shot® Function

By activating the PRESSURE SHOT function through the menu, the instrument stores the HOT tire pressures without having to press any buttons. This feature allows you to save the pressures immediately, preventing the tires from cooling and obtaining unrealistic values.

Pressure Accuracy CLASS: 0.1%

  • Maximum error at 5 BAR: +/- 0.005 BAR -- (0.072 PSI)
  • Maximum error at 1 BAR: +/- 0.001 BAR -- (0.014 PSI)


  • The HPM4X digital gauge does not require calibration. The internal microprocessor calibrates the tool every time it is turned on to ensure correct readings at 100%.

Pressure and Temperature

  • Pressure measurement units in BAR and PSI
  • Temperature measurement units in CELSIUS and FAHRENHEIT

Set the direction of saving data depending on the circuit

  • Clockwise
  • Counterclockwise
  • You can set whether to start from the front or rear wheels
