11.6.4 How To Perform A Free Air Calibration on TRo2
Q: How do I do the free air calibration procedure on TRO2?
The TRO2 has red status LEDs for each channel. When powered, the LEDs blink at a slow rate until the corresponding sensor has reached normal operating temperature. After installation, the TRO2 requires free air calibration. This should be done with the sensors dangling in free air. The environment must be free of hydrocarbon vapors. It is suggested that the free air calibration be performed outdoors.
To start the calibration:- Turn the free air calibration trim-pots on the TRO2 full counterclockwise.
- Turn on power, typically by turning the motorcycle on, and wait for 60 seconds so the sensors can heat fully.
- Then slowly turn each free air calibration trim-pot clockwise until the corresponding LED starts flashing at a rapid rate. ry to set each trim-pot so that its LED has just started to flash.
