Depth Target
The current versions of the depth targets (item# 6110FST)
contain punched holes that are cut to the minimum cone
diameter for each cone size. To check the cone diameter,
place the meter on the ground, upside down, and try to
slide the appropriate-sized wear guide hole over the cone.
If the cone will fit through the hole, it should be replaced.
Dial Caliper/Micrometer
Measure the diameter of the cone using a dial caliper or
micrometer that allows you 0.001-inch measurements.
Place the caliper/micrometer on the shoulder of the cone.
Figure 1 the layout of the shoulder. Figure 2 illustrates
the proper placement of the caliper. Cones should be re-
placed when the diameters are less than those indicated in
table 1.

3. Attach new cone into meter shaft
