3.2.2 Calibration of Rx
If the Quality of the probe is 25% or lower, make again the calibration. If the result is still
25% or lower it is recommended to change the probe.
3.2.3 Dosing mode
Dosage of the chemical is in proportion to the difference between set point and the
reading carried out by pH and Rx probes.
The greater the difference between the value read from the probe and the value set as set
point, the higher the percentage dosing pump.
(The duration of dosage also depends on the percentage of its maximum limit set to limit of
proportionality)
Proportionality is obtained with a time - break dosing cycles of about 5 minutes
Every 5 minutes the pump acquires values from probes and compares them with set point
set, by comparing is calculated the time dosing for that cycle.
If the difference is minimal the pump will dose for just a few seconds and then await the
end of 5 minutes cycle before performing a new reading and a new strength.
Es.: Set point pH = 7.00, L1= pH 7.60, %pH=Set = 0% , %pH=L1 = 80%, reading of pH
probe 7.30
The pump calculates a time dosing = 80% x 50% = 40% over the 5 minutes (300
seconds), the pump will dose for 120 seconds
