This control displays and adjusts the fresh gas flow (FGF), given in liters per minute.

Click on the edit box to edit the flow setting directly (double-click to select the number to overwrite). The number here will display in red when it exceeds the value at the top of the gauge.

The upper and lower 'spin-buttons' increase and reduce the fresh gas flow (FGF) setting. Click to adjust; hold down to adjust continuously.

Fresh gas flow (this number) will increase naturally with increased vaporization (that is, with additional agent vapor) when Vapor is enabled in the Special Menu or on the Control Panel.
