A TMOSPHERIC S ENSING M ODULE
The atmospheric sensing module measures absolute pressure, air temperature, and
relative humidity. These measurements are used by WinPEP to correct power and
torque measurements to standard atmospheric conditions according to a DIN, SAE, or
other formula.
LED indicator description
The green LED glows when the atmospheric sensing
module is receiving power.
The flashing amber LED indicates the module processor
is operating properly.
