VIEWINGMECHANICALMEASUREMENTRESULTS
Theresultsformechanicalpower,torque,speedandmotorslipcanbeselectedonthePOWERDATAscreenbypressingtheSource
SelectbuttonandthenselectingMOTOR.ThisselectionisonlyavailableifanMTchannelisinstalledintheCH4positionandatleast
torqueorspeedisconfiguredtobemeasured.
