alarms (+ and -) are used. A difference kind of diagnostic can be provided by a precision
check resistor in place of one cell to give continuous Analyzer/Controller checking at one
value. Also see 15.11 Appendix J – Discussion on Chemical Interferences on Measured

Parts Rinsing
Parts rinsing is usually controlled by conductivity to obtain adequate rinsing without
wasting excess water, whether a single stage or a counter-current series of tanks. The
two-cell ratio approach can determine whether inadequate rinsing is due to low flowrate
or due to poor supply water quality.
