About

MiniProf Criterion

Features
Read full description

MiniProf Criterion is the mobile app for performing profile measurements with a MiniProf BT instrument. It currently supports profile measuring with MiniProf single head Wheel, Rail and Brake systems. In addition to profile measurements, Criterion includes selected calculations and alignments from the complete Envision software package. MiniProf Criterion is designed for use on smartphones and provides an intuitive measuring process, which works just like MiniProf Envision. The app supports numerous languages for a personalized user experience. Measurement schemes enable easy data collection of user-defined patterns of measuring locations resulting in efficient and reliable measurements. In addition, the GPS location can be attached to the individual measurement. Instant results are shown upon completion of a measurement, along with optional alarms using limits configured within the selected reference profile. Profiles and result values can be viewed later and easily transferred to a Windows based PC for detailed analysis in MiniProf Envision. Please note: The app requires instruments are capable of Bluetooth BLE. Please contact Greenwood Engineering to make arrangement for instrument upgrades if necessary.
