我相信這個探針上有一個電池常數，K = 1.02。在手冊第17頁，有關于如何查看探針數據（電池常數）的說明。 我能滾動不同的 P4.#，除了 P4.4 是1.016之外，所有這些都是 1.000。 但是，我不知道如何選擇或更改其中任何一個。 儀器可以為這個 s/n 探頭檢測到正確的K嗎？ 如果不行，能否提供更多關于如何輸入我們的探頭K 的說明？ 謝謝。
回答：
我們手冊中描述的 P4.x 功能目的不是為了調整，而是為了“檢查”校準后的電極常數值是多少。 隨著時間，EC探頭會慢慢減少使用壽命，如果電極常數值超出 0.8~1.2 范圍，則意味著需要換新的 EC 探頭。
Q: Can I manually input the cell constant of my EC probes into benchtop EC meters?
The probe has what I believe is a cell constant taped to it, K=1.02. On p. 17 of the manual, there are directions on how to view the probe data (cell constant). I was able to scroll through the different P4.#, all of which were 1.000 except P4.4 which was 1.016. However, I could not figure out how to select or change any of them. Does the instrument sense the correct K for this s/n probe? If not, can you provide more directions on how to input our probe's K? Thanks.
Answer:
The P4.x function described in our manual is not for adjusting purpose, that is for “checking” what’s the cell constant value after calibration. With time goes by, the EC probe will age naturally, if the cell constant value is out of 0.8~1.2 range, it means a new EC probe is required.
8373并沒有缺少“ ppt”單位，僅是因為您測量的液體濃度非常低，所以我們認為您現在只能看到“ ppm”。
在86021的數據表中，為何工作范圍的上限是50°C，但溫度范圍的上限是60°C？
