•Recovery mode – Recovers and recycles refrigerant from a vehicle’s A/C system. This mode is most often used prior to opening an A/C system to atmosphere to replace a system component.

•Vacuum mode – Removes residual air and moisture from a system previously opened to the atmosphere. This mode also allows a technician to verify that the A/C system will hold a vacuum for a certain length of time.

•Charge mode – Select this mode to add refrigerant to an A/C system; also most commonly used to “top off” the system.

•Snap-Shot mode – Monitors and records important operating information including the high- and low-side pressures, ambient temperatures, A/C vent temperatures, ambient humidity, and (optionally) vent air flow velocities. This information is used to diagnose and measure A/C performance before and after service.

•Next menu – Displays Menu 2.
