Question
Chapter 4, Problem 1RQ
To determine
The purpose of the adjustment screw found on the face of analog meters.
Expert Solution & Answer
Answer to Problem 1RQ
The purpose of the adjustment screw found on the face of analog meters is adjustment of needle in order to obtain an accurate reading.
Explanation of Solution
While using an analog meter, it should be ensured that the indicating needle is pointing towards zero before taking measurement in the meter. For this adjustment of the needle, a screw is provided on the face of the analog meter. The role of screw is very important to get an accurate reading as even a slight turn will cause the movement of the needle.
