3. 70 ppm or much higher than 430 ppm it is not necessary to calibrate the T Mini That is because the value of neutral clean outdoor air is between 380 ppm and 420 ppm A deviation of 5 is common with this type of measurement equipment Please keep that in mind when setting your CO values In case of a greater deviation calibration is necessary Please continue with the follow ing step TechGrow T Mini calibration procedure CALIBRATION MENU 1 2 3 4 Disconnect the power supply to the T Mini CO controller Reconnect the power supply after 20 seconds The display will first show the type and software version of the controller Next the calibration menu is shown image 1 after 5 seconds you will be asked if you would like to continue with the calibration Choose Yes image 2 If you do nothing or choose No the controller will return to the main menu without calibrating the sensor CALIBRATION PROCEDURE The calibration menu will guide you through the procedure step by step Please note step 5 is your last chance to terminate the calibration and return to the main menu without making any modifications gt CO calibration Continue gt image 1 Yes No gt image 2 Press the button for 10 seconds gt image 3 Wait 10 seconds gt image 4 Arrows gt will appear on the second line of the display If the button is released before the line is
