| Pressure Meter: This meter measures the pressure of the gas inside the ideal gas container. You must attach the pressure meter to a red hotspot on the container (see Container (Ideal Gas)). Only the probe connects to the hotspot on the container. The meter itself appears to the left. You can move the meter, but you cannot delete it. To delete the meter, you must delete the probe. You must place a pressure meter to plot pressure using the graph tool.
