Remark(Instruction for Cleaning And Maintenance)
1）There is a protection "dead band" for output ot action. The control output in action when the PH measuring value goes above the set value 3~5 digitals.The control output off when the PH measuring value below the set value 3-5 digitals.(when slide HI/LO switch in "HI" position.)
2) The Control output will be automatic turned off when slide the {PH/SET} function switch in "SET" position while adjusting the set value.
3)It must to pull out the power plug( turn off) when cleaning the controller.
