仪器的校正
Calibration of the instrument
校准方式采用三点校准。校准过程中自动识别三种pH缓冲溶液;并设有校准保护功能,非法校准不被执行;且校准过程只需单键操作,方便快捷。
Three-point calibration should be adopted. During the calibration process, three kinds of pH buffer solution will be automatically identified. There is calibration protection against illegal calibration. The calibration can be easily and conveniently done by means of single keystrokes.
校准前请按要求配制好pH值为4.01、6.86和9.18的三种缓冲溶液。校准前电极部分必须浸没在清水或被测溶液中活化5分钟。
Before calibration, prepare three kinds of buffer solution with pH values of 4.01, 6.86 and 9.18 respectively according to the requirements. Before calibration, the electrode should be dipped into clean water or the test solution for 5 minutes.
校准方法如下:当处于测量状态时qnryb.com
The calibration method is as follows: (under the measuring status)
(1) 按"SET"键,直到仪器显示“CAL”, 即进入校准状态。
(1) Press the"SET"key until the instrument displays “CAL”, which indicates that the instrument enters into the calibration status.
(2) 按"Enter"键,仪器显示“C 1”。将清洗干净的电极插入配置好的第1种标定液等待3-5分钟。按下"Enter"键,显示由“C 1”变换为“C 2”后。再将电极拿出第1种标定液,清洗干净。(严格遵守操作顺序)
(2) Press the "Enter" key, and the instrument will display “C1”. Then put the cleaned electrode into the first kind of calibration liquid prepared before hand and wait for 3-5 minutes. Press the "Enter" key until the instrument display shifts from “C1” to “C2”.Fetch the electrode out of the first kind of calibration liquid and wash it. (Strictly follow the required operation sequence.)
(3) 把电极插入配置好的第2种标定液等待3-5分钟。按下 "Enter" 键,显示由“C 2”变换为“C 3”后。再将电极拿出第2种标定液,清洗干净。
(3) Insert the electrode into the second kind of calibration liquid and wait for 3-5 minutes. Press the "Enter" key until the instrument display shifts from “C2” to “C3”. Fetch the electrode out of the second kind of calibration liquid and wash it.
(4) 把电极插入配置好的第3种标定液等待3-5分钟。按下 "Enter" 键,显示由“C 3”变换为“温度值”后。再将电极拿出第3种标定液,清洗干净。
(4) Insert the electrode into the third kind of calibration liquid and wait for 3-5 minutes. Press the "Enter |key until the instrument display shifts from “C3” to “temperature value”. Fetch the electrode out of the third kind of calibration liquid and wash it.
