The carrying case for the XK-550 Digital/Analog
Trainer has been designed to hold a meter and
many of the most important tools. The layout below
shows a suggestive layout for equipment and tools.

The sloped side pocket of the case next to the
trainer can accommodate a wide range of different
meters.
