Preset Selections
These options allow you to select from already configured scope setups for commonly tested
items. Six preset configurations are available; three for Preset A and three for Preset B. These
preset conditions are permanent and cannot be erased or modified. However, you can construct
and store additional presets within the D7 Diagnostic Tool as explained in the Scope and
Multimeter chapter of this manual.

•
Preset B :
