		Depth can be measured by inserting the depth rod into the hole you are measuring. When you adjust the jaws using the thumb screw, the rod will protrude from the end of the caliper.

		Step 1 – Position rod Position the rod so that it is flat against both the bottom of the hole and an internal side of the hole. Step 2 – Move thumb screw Move the thumb screw gradually until the end of the end of the beam scale makes contact with the top of the hole.

		Step 3 – Turn lock screw Turn the lock screw to tighten the jaws so that you can remove your object and take your reading. Step 4 – Read measured value Read the measured value (See How to read a metric dial caliperor How to read an imperial dial caliper).
