18.0 Set the dosing OnTime and O Time

A dosing cycle includes the OnTime and the OffTime that the peristaltic pump

doses the system for. The arrow symbol on the display will ﬂ ash during the dose

cycle. Adjustments for OnTime and OffTime will be required so that three dosing

cycles only change the pH value by 0.1 pH.

• ‘OnTime’ is the length of time the peristaltic pump will dose for. The ‘OnTime’

can be set from 1 to 60 seconds.

• ‘OffTime’ is the delay time between each dose. This gives the system time to

mix the pH stock solution thoroughly, so the pH controller connect can measure

the changes being made before needing to dose again. The ‘OffTime’ can be set

from 1 to 60 minutes.

• Start with a long ‘OffTime’ and adjust back as you go. The more thorough the

mixing in the tank, the shorter the ‘OffTime’ can be.

Press ‘menu’.

Press ‘’ to ﬁ nd ‘OnTime’. Press ‘enter’.

seconds. Press ‘enter’ to save.

To set the OffTime value:

minutes. Press ‘enter’ to save.
