SenseAir森尔二氧化碳传感器实校准说明

　　Rough handling and transportation might result in a reduction of sensor reading accuracy. With time,

　　the ABC function will tune the readings back to the correct numbers. The default “tuning speed” is however limited to about 30-50 ppm/week.

　　For post calibration convenience, in the event that one cannot wait for the ABC algorithm tocompensate for possible calibration offset two manual calibration procedures are offered. A switchinput is defined for the operator or master system to select one of the two prepared calibration codes.

　　Optional calibrations are bCAL (background calibration), which requires that the sensor is exposed to fresh air (400 ppm CO2) and CAL (zero calibration), which requires the sensor measuring cell to be completely evacuated from CO2 e.g. by exposing it to Nitrogen or Soda Lime CO2 scrubbed air.

　　Make sure that the sensor environment is steady and calm!

  （粗略的搬运和运输可能会降低传感器的读数。随着时间的推移，

　　ABC函数将读数调整到正确的数字。然而，默认的“调谐速度”限制在大约30-50 ppm /周。

　　用于校准后的方便，如用于校准ABC算法可能无法抵消补偿等提供了两个手动校准程序。一个开关量输入定义的算子或主系统选择一个准备校准规范。

　　可选的校准BCAL（背景校正），这就要求传感器暴露于空气清新（400 ppm的CO2）和CAL（校零），这就要求传感器测量细胞完全撤离CO2通过暴露于氮或二氧化碳空气擦洗碱石灰。

　　确保传感器环境稳定、平静！）
