🔍 Key Concepts

• Parallax error when reading instruments • How to align your eye with a pointer and scale • Difference between reading a liquid column (like a mercury barometer) versus an aneroid barometer with a pointer

💭 Think About

• Think about what happens if your eye is not lined up with the pointer and the scale. Will the reading appear higher, lower, or accurate? • Which eye position makes the pointer look like it is exactly on one mark, rather than between two, no matter which side you move your head? • Consider how you are taught to read other pointer instruments (like an engine gauge or compass repeater). Where do you place your eye to avoid parallax?

✅ Before You Answer

• Identify which options would clearly cause parallax error (reading too high or too low depending on viewing angle). • Remember that an aneroid barometer uses a pointer and dial, not a visible liquid meniscus. • Confirm which choice positions your eye so the pointer and its scale mark are in the same line of sight.

To avoid error, how should you read the scale of an aneroid barometer?

With your eye slightly above the meniscus

With your eye to the right of the pointer

With your eye to the left of the pointer
