The program of the type "inject" is started each time injection valve A is

switched to the "INJECT" position. For the determination of nitrate and

phosphate, the full-scale range is briefly narrowed to 5

µ

S/cm and this

range marked by marking signals. After 20.0 min the IC system is ready

for the next injection. If there is no new program start within 50 min after

the last injection, valve A is automatically switched to the "FILL" position,

the 709 IC Pump and 752 Pump Unit are stopped and the program

ended.
