Question

1. where do you need to orient your eye level to take an accurate reading of the meniscus?

a. exactly parallel to the meniscus
b. slightly above, looking down at the meniscus
c. slightly below, looking up at the meniscus

Explanation:

To take an accurate reading of the meniscus, the eye - level should be exactly parallel to the meniscus. If the eye - level is above (looking down), it will cause an over - estimation of the volume (parallax error - high reading). If the eye - level is below (looking up), it will cause an under - estimation of the volume (parallax error - low reading). Only when the eye - level is parallel to the meniscus, the reading is accurate.

Answer:

A. Exactly parallel to the meniscus
