DYNertia3 Quick Start (Inertia- Chassis type) 

 

Troubleshooting 

 

Assessing test results- Poor settings 

Most poor results are either due to electrical interference (via PC, accessories or DYNertia hardware) or from poor 
selection of start and end points for the test. 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

OK

-

 It has a good start point and decisive end 

   

 

OK

-

 It has a good start point and decisive end. 

 

 

 

 

 

 

 

 Note:

 Personally I would set the max RPM lower to prevent 

 

 

 

 

 

 

 

 the trace from dropping away and risking doubling back under. 

 
 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

NOT OK

- Both these traces are running back under themselves at the test end. The trace should not run back under 

itself or you effectively end up with 2 power readings for every RPM point and this is confusing to calculations we run. 
 
Both the above files have a poorly set Max RPM (set in “Record Settings” field as below). 
 

 
 
There is nothing wrong with the data, just needs a better setup of max and min RPM/speed 
(start and end) at test time.
