SP510通过光学测量硬度，没有数据的显示，只能通过indicator solution作为分界点，来判断水样硬度值是否在设定范围以内。通过设置报警线来触发报警，通过继电器可以实现反馈控制。连续2个周期以上的设定点激活报警，1周期低于设定点取消报警

三个按键：ALARM OFF；ZERO CAL；HARD CAL
两个指示led，SOFT和HARD

用过滤、溢流装置，用它来调节就行。溢流方向，也是可以用来泄压的，所以调压力就调溢流方向

导致水样回流入试剂管路

把水样的连接管路冲开，导致仪器内部漏水，

Yes!  Changing the alarm trip point is accomplished by installing the appropriate buffer and indicator solutions.
Allow the instrument to run for two hours to purge the old reagents
Recalibrate instrument.

Colorimeter needs to be cleaned monthly or as needed
Reagents
Replace buffer and indicator reagents every two months.
Discard old containers and any unused contents.
Standardization
Standardization must be performed after reagent installation or when an optical system component has been replaced.
Replace pump tubing
Every 6 months < 27oC
Every 3 months > 27oC
Replace remaining instrument tubing annually

One SPDT alarm relay for external annunciator or automatic water softener shutoff/regeneration cycle
2 consecutive cycles above set point activate alarm
1 cycle below set point cancels alarm
NO 4-20mA output

±10% of set point (0.3-2mg/L range)
±4% of set point (5-100mg/L range)
