具体操作细节：
1. 系统做销售合同型号写S8-0053正向插针/反向插针，打印合同和出库单把“正向插针/反向插针”字样去掉，以保证客户的合同、单据、发票型号一致性（建议发带插针的货在留底出库单上另行备注清楚）。
2. 进销项发票统一不带插针字样，进项全名称为：环境监测仪器*CO2传感器 型号 S8-0053。
Note 1: Sensor is designed to measure in the range 400 to 2000 ppm with specified in the table accuracy.
Nevertheless exposure to concentrations below 400 ppm may result in incorrect operation of ABC algorithm
and shall be avoided for model with ABC on.
Note 2: Sensor provides readings via UART in the extended range but the accuracy is degraded compared to
specification in the table one.
Note 3: In normal IAQ applications. Accuracy is defined after minimum 3 weeks of continuous operation with ABC.
However, some industrial applications do require maintenance. Please, contact SenseAir for further
information!
Note 4: Accuracy is specified at room temperature +25°C and at normal pressure 101.3 kPa. Specification is
referenced to certified calibration mixtures. Uncertainty of calibration gas mixtures (+-1% currently) is to be
added to the specified accuracy for absolute measurements.
Note 5: See specification (Modbus on SenseAir_R_S8 rev_P11_1_00.doc preliminary specification)
Absolute maximum ratings
Stress greater than those listed in Table 2 may cause permanent damage to the device. These
ratings are stress ratings only. Operation of the device at any condition outside those indicated
in the operational section of these specifications is not implied. Exposure to absolute maximum
rating for extended periods may affect device reliability
