# 9.1.4 Pressure Sensor Calibration ### “This calibration establishes the current pressure as the reference point for zero altitude.” **Step 1**. Locate the '**PRESSURE**' section visible on your screen. This area will provide access to calibrating the Pressure Sensor, as shown in the screen below.

**Step 2**. Click on the “**Calibrate**” button to start the calibration of pressure sensors. After completion of the calibration process, you will see the following screen.

By completing the pressure sensor calibration, you have now set the current pressure as the reference point for zero altitude, ensuring accurate measurements in your system. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
