APPLICATIONS OF A DIAL INDICATOR.
(d) Care.
Dial indicators and other instruments that have a
mechanically-operated dial as part of their design are easily damaged by
misuse and lack of proper maintenance. The following instructions apply to
dial indicators in general:
1 Make sure the dial indicator that has been selected for use
has the range capability required. When a dial indicator is extended beyond
its design limit, some lever, small gear, or rack in the housing must give
way to the exerted pressure applied on it.
The dial indicator will be
rendered useless if this happens.
