| 25 kPa (-0.75 bar) | V | approx. 0.5 |
| 50 kPa (-0.50 bar) | V | approx. 1.0 |
| 75 kPa (-0.25 bar) | V | approx. 1.5 |
| 100 kPa (±0 bar) | V | approx. 2.0 |
| 125 kPa (0.25 bar) | V | approx. 2.5 |
| 150 kPa (0.50 bar) | V | approx. 3.0 |
| 175 kPa (0.75 bar) | V | approx. 3.5 |

Measurement range: 15-235 kPa
The pressure given in kPa denotes the absolute pressure, i.e. 100 kPa is equivalent to atmospheric pressure at sea level.
When checking the pressure sensor with a pressure/vacuum pump a lower voltage reading may be obtained at high altitude.
