🔍 Key Concepts

• Compound gauge vs. standard pressure gauge on a refrigeration/air-conditioning manifold set • Typical color coding for low-side and high-side gauges on a manifold set • How the scale markings on gauge "A" differ from those on gauge "B" in the illustration

💭 Think About

• Look closely at the scale on gauge "A": does it show only positive pressures, or both vacuum (below atmospheric) and positive pressure? What does that tell you about the type of gauge? • Compare gauge "A" with gauge "B". On a typical manifold set, which side (low or high) is connected to which gauge, and what are their usual colors? • Think about which side of a refrigeration system needs to read both vacuum and pressure during evacuation and charging. Which gauge in the picture is in that role?

✅ Before You Answer

• Verify whether gauge "A" has vacuum markings (often extending to about 30 inches of mercury below zero) as well as positive psi readings. • Confirm from your HVAC/refrigeration notes which side’s gauge (low or high) is normally blue and which is normally red. • Before choosing, double-check that the description you pick matches both the gauge type (compound vs. standard) and the usual color code.
