Menu Structure And Settings - Autogrow pH Mini Installation And User Manual

Menu Structure and Settings

The menu structure of the pH Mini Controller is split into 2 sections - Readings
and Settings. Toggling between the two menus is achieved by pressing the Menu
button. Once in the Readings or Settings Menu, navigation is achieved through
the Up and Down arrow keys. Settings may be changed by holding down the Edit
button and then pressing the Up or Down arrow keys. The new setting is
automatically saved when the edit button is released. Some Readings can be
zeroed; to do this hold down the Edit button and then press the Down arrow.

The desired pH Level
The time in seconds that the peristaltic pump
will run to add acid (lower) or alkali (raise)
The time in minutes between doses to
allow for mixing to occur
This switches the controller to dose either acid
(lower) or alkali (raise)
This forces a dose to occur straight away
If the measured pH deviates from the setpoint
by more than this value, the alarm will
sound (if enabled)
If the Dose Count per hour reaches this
value then the alarm is sounded and the
dosing is inhibited (if enabled)
This enables/disables the alarm functions
Calibrate using 7.0pH buffer
