In excess quantity storage register.
9. water quality automatic testing method according to claim 6, it is characterised in that before described water quality automatic detection,
Self-check of device is carried out, self-inspection is comprised the following steps：
1. reagent test
After automatic detection device start, self-checking command is sent by master control borad, the reagent storage each amount of reagent in matrix room is lacked
The property lost detection：
If there is certain reagent missing, the reagent name that master control borad sends alarm command and will lack is included on operation display panel,
The artificial addition of prompting；
If intact mistake is upchecked, self-inspection enters next step；
2. blender seal inspection
Master control borad provides electronic eyes identification light sensation instruction, detection time 1~3 second first：
If confined space has printing opacity, master control borad sends alarm and points out " closed sexual abnormality " in operation display panel；
If seal good check passes through, self-inspection enters next step；
3. mixing reactor abnormality detection
Master control board starting mixing reactor, hybrid drive work, the displacement transducer feedback inside mixing reactor
Signal is to master control borad：
If thering is abnormal master control borad to send alarm and pointing out " hybrid drive failure " in operation display panel；
If hybrid drive is working properly, self-inspection terminates.
10. water quality automatic testing method according to claim 6, it is characterised in that described detection method, in detection
Before, white balance correction is carried out to electronic eyes, white balance correction light source continues bright 90~110ms, electronics ophthalmic record white balance data
It is worth and stores.
