Chapter 4: ‘Setup’ Menu Options
Hardware- Setup Menu (cont.)
Hardware Connections: An overview of terminal designations on the
DYNertia3 hardware. Handy if your decals are not visible.
Circumference Calculator: Tool to help calculate your rollers
circumference if you do not already know it.
Units will be metric or imperial based on your choice in menu
“Setup/Software” (Imperial or Metric). Pressing the “Circ” button will
transfer the value into the “Roller Circumference” field in this ‘Hardware’ menu.
Moment Of Inertia Calculator: Tool to help you calculate the Moment of Inertia (MOI) of your dyno. If the
dyno design incorporates multiple selectable flywheels then their values can be saved separately as a
“Second Mass” and “Third Mass”.
Once the values of components have been entered into the rows they can be saved (or loaded) for later
use and reference.
Simply press one of the numbered buttons and the MOI value
will be directly transferred into the “Inertial Mass Constants”
field in this ‘Hardware’ menu.
‘Eraser’ button clears the filled in fields so new values can be entered.
From within the ‘MOI’ calculator you can press the icon of a weight to get a
reference of density of metals as shown here.
