[求助]BAYER-500故障

你好！YEEC老师，BAYER-500机器开机自检报错：31。不知道是什么故障。头一次接触这种机器。特向你请教。多谢了！

Strip Detector Setup error (31)
When the strip detector "detection level circuit" is
calibrated, if the level count was not between 10
and 254, inclusive, this error is set. A high count
indicates that there was too much light reflecting
from the table or that there was a circuit
malfunction..

光检测有问题。用的是什么尿条你的仪器必须专业工程师修，我们遇到多少次31号报警了

多谢了。机器故障已经解决了，确实是光路故障。但还有一个故障不知到触摸屏有没有校正菜单。

可以校正但不知故障现象是什么
