ABSTRACT
In this application the vernier gauge is being used in conjunction with an engineer’s straight edge. Figure 13.3 shows a Vernier gauge in greater detail. This instrument measures to an accuracy of 0.02mm, which is quite adequate for most vehicle repair and maintenance work. As indicated in the diagram, the instrument is versatile as it may be used for internal, external and depth measurements. The instrument should be treated carefully and kept in clean dry conditions when not in use.
