Data Acquisition (cont.)-
Simple screw type terminals on a removable terminal plug allow for quick and easy sensor wiring. Both a 5 Volt and 12
Volt output to power auxiliary sensors is also present if required.
An additional digital channel is provided if you wish to have engine RPM directly measured (via a Hall sensor or DTec’s
‘RPM adapter’). This option can help reveal tyre slip/growth on a chassis dyno or centrifugal clutch engagement RPM.
There is a dedicated analysis screen to examine slip/tyre growth.
File Management-
Designed to perform testing quickly- common user settings are saved to reduce set up times and any personal notes
you’ve entered in the provided form (general, vehicle, owner details etc) can be saved as a ‘template’ and applied to
other runs to save re-entering the details, even copies the Run’s set up details. Files can also be set to ‘auto name’, the
file name simply increments with each test (and can carry over any personal notes), no need to even re-enter a name.
Advanced previewing function (‘DYNertia3 File Explorer’) shows graphs, summary details and the data table of all saved
runs, this allows quick selection for loading into the main graph screen or for file management purposes. A cursor is
even available to highlight points of interest on the graph and indicate that same location in the data table- no more
browsing through cryptic file names!
User configurable directories- have as many separate directories to store your runs in as required and file protection can
be applied to prevent individual files from being accidentally changed or overwritten if required.
Printing-
Color print outs of your chosen graph or overlaid graphs (up to 5 printed on same graph) is only a mouse click away,
complete with preview. A report page is also generated that has a summary of all the important test conditions, max
readings, date, time, company logo, graph notes etc.
Printouts includes Run trace sets legends, colors and filenames, the graphs ‘grid lines’ can even be turned off!
Comments can be placed on the graphs to appear on the printouts.
Printing of specific areas of interest can be performed using the manual ‘zoom’ function.
Additional Functions-
‘Point by Point’ testing mode for brake style dyno’s allows recording of individual data points at the press of a button.
These individual data sets are then combined to construct a conventional Run trace for easy analysis and comparisons.
For dyno competition entertainment, after a run maximum Power and Torque can be displayed in large format for crowds
to easily see (result in both imperial and metric units).
Graphs are fully auto-scaled, Power, Torque and RPM scales are automatically configured for optimal display.
Flexible options for performing a test; a Run can be from ‘start’ command to ‘stop’ command or from ‘start’ command to
zero power. A minimum speed can also be specified and data below this will be discarded, this eliminates any different
start points of tests due to operator error.
All dial gauges have digital displays incorporated.
Gauges display ‘real time’ data during monitoring or setup. Ideal for steady state tuning with a brake type dyno! (only
RPM is displayed 'real time' in Inertia mode)
Data ‘Smoothing’ that is applied to the Power traces is adjustable to ensure you don’t miss out any detail but still end up
with optimal appearing graphs.
There is a “Losses” function that can be used to measure and apply a correction to data for mechanical losses in your
dyno system like friction and windage (typically very small) even or/and for driveline losses due to friction.
DYNertia3 is fully isolated (optically) from the PC, this helps prevent any damage to the PC from incorrect connections
(power DYNertia3 from a battery source for this full isolation!). DYNertia3 is also protected from reversed polarity supply
connection.
A ‘system in motion’ (“Run”) output is available that is active as long as the flywheel is rotating, or a function is used that
may result in rotation. This can directly control a relay to operate safety control systems/warnings if required or for
automatic fan controls etc.
