Fault
Possible causes
Measures for resolution
The chlorine measuring cell
displays too much with
respect to the DPD-1
measurement
May occur when using "water fining
agents". Chlorine-oxygen bonds are
contained in some of these agents which
react with chlorine to make chlorine dioxide,
thus distorting the measuring signal by
greater values
Refrain from dosing this agent. A change of water might be required.
Use of "organic chlorine".
When using organic chlorine products,
cyanuric acid accumulates in the swimming
pool water. The DPD-1 method displays
excessive chlorine content to which the
measuring cell cannot be adjusted
Replace the water completely and use other chemicals for disinfection
