(a) Hold the body of the depth gauge
against the surface from which the depth is to be
(b) Extend the rule into the hole or slot.

(d) Withdraw the tool from the work and
read the depth on the rule.
(2) Vernier depth gauge. To measure the depth
of a hole or slot with more accuracy than is possible with
a rule depth gauge, proceed as follows:
