• The return value is 2 bytes wide unsigned total volatile organic compound concentration value, the unit is μg/m3, the resolution is 1 μg/m3, and the range from 0 μg/m3 to 65,534 μg/m3. Value 0xFFFF (i.e. 65,535 μg/m3) specifies a sensor error.
• FRC 2-byte: FRC return value is the total volatile organic compound concentration value +4 (i.e. 0x01F8 = 504 is 500 μg/m3). Because of FRC predefined values the raw values from 0xFFFC to 0xFFFF (i.e. 65,532 μg/m3 to 65,535 μg/m3) cannot be passed.
