then navigate through the menu to **Calibrate** then press **Fill**.

### Set the 1st Calibration Point (Ambient/Empty)
**Clear the Line:** Remove the purge tube from container or liquid. Press **Select** .
**Capture Reading:** Press **Select** . The unit will purge the line and display `Purging > Waiting for Pressure to Stabilize`. This sets the baseline "zero" value for ambient pressure.
{% endstep %}
{% step %}
### Set the 2nd Calibration Point (Reference Height)
**Prepare Reference Water:** Place a container (a glass is ideal) under the fill & purge tubes. Fill it with water until the water level exactly hits the 100mm mark you made in Step 1.
**Check Value:** Ensure the measurement value on the screen matches the height of your water (e.g., 100mm). If you used a different height, update the value on the screen now.
**Capture Reading:** Wait for the pressure sensor value to stabilise (fluctuating by only a few points). **Select** . The unit now knows the pressure-to-depth ratio.
{% endstep %}
{% step %}
### Run a Test Fill With Water
**Set Your Target:** Place your actual can or bottle in the filling position. Decide where you want the liquid to stop and mark that spot on the purge tube.
**Measure & Program:** Measure from the bottom of the tube up to this new mark. Enter this value (in mm) into your Fill Preset.
**Test:** Connect your water source to the yellow carbonation cap (max 15psi). Select your preset, place your container, and press Run.
