7. Setting on RS-485, Data Transmission Test and environment parameters There are 3 groups in setting tab. The description of each item as below. Environment Parameters (1) Air Pressure Modbus Protocol (2) station ID (3) Baud Rate (4) Date Frame (5) Modbus Echo Test Enable/Disable (6) Modbus Echo Test Result Reset CO2 Auto Calibration (7) CO2 Auto CalibrationFunction is enabled if the bar color green, otherwise function is disabled. In the general environment, the CO2 concentration usually measured as 400ppm. The environments as From Room/ Office with the condition as midnight period & nobody status, the CO2 concentration usually measured as 400ppm. Thus, eyc-tech use the average statistics values for 7 days to implement Self-Correcting feature. This feature is not adaptive to use in special environment as Factory/ Plant Greenroom where the CO2 concentration may keep on high value & keep for long period.
