SP 1
Above the required pH value, e.g. 52 % (correlates with pH 7.28).
Pulse frequency for SP 1
72 (maximum value (correlates with 7,200 strokes per hour).
The dosing capacity of the pump is then fully utilised.
SP 2
Below the required pH value, e.g. 48 % (correlates with pH 6.72).
Pulse frequency for SP 2
72 (maximum value (correlates with 7,200 strokes per hour).
The dosing capacity of the pump is then fully utilised.
