Measured channels | TestLogger Knowledge Base

Collector Mini allows to measure variety of channels for performance analysis, but many of the measured values provides possiblities to calculate more relevant values for analysis. This page opens a little bit what items are possible to measure and some exaples what values can be calculated from the measured data.

Values available for measurement

Item	Notes
Lap times
Split times
Throttle and brake signal	Can be any signal from the receiver
Steering signal	Can be any signal from the receiver
Electric motor RPM
Drivetrain RPM/speed	Measure speed (or motor RPM) with a speed sensor
Diff outdrive speed	Measure speed from both sides of diff outdrive
Longitudal acceleration
Lateral accelaration
Vertical acceleration	Use to measure air time
Yaw rate
Pitch rate
Roll rate
Temperature	Follow for example motor temperature

Calculation possibilities from measured data

Item	Notes
Throttle rate	See how fast input changes the driver is making by calculating throttle speed from throttle position.
Steeting rate	See how fast input changes the driver is making by calculating steering speed from steering position.
Acceleration vector	Evaluate how maximum grip is used in cornerning, braking and accelarating
Distance	Measure driven distance from speed measurement
Differential slip	Calculate speed difference between diff outdrives
Slipper operation	Calculate slipper operation with help of motor RPM and rear wheel speeds
Understeering/oversteering	This can be calculated for example by calculating how much steering is used during a lap or by with help of Lateral accelaration and yaw rate.
Track map	Draw a trackmap from distance and lateral acceleration.

Debugging values

Item	Notes
Timestamp
Raw measurement of receiver channels
Raw measurement of speed channels
Raw measurement for lap trigger signals	Used for finding issues with missing laps and splits
