• 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.
