Calibration = Allows access to "probe Cal".
Download = Allows the user to export the data files.
Upload = Allows the user to import program settings.
USB Settings = Allows the user to change the USB settings.
Factory Reset = Restricts access to the factory reset feature.
Once the password is set the controller will require a password to access any of the
menus. If the password is lost or unknown it will be necessary to call technical
service to gain access to the controller menus.
4.6.9 Software Version
From the Software Version screen view the current software that is running in the

controller.
4.6.10 Factory Reset Function
The Factory Reset Function will reset all of its internal parameters to the factory default
values.
Be absolutely certain you want to reset all the parameters back to the factory
defaults. Once the reset takes place there is no way to retrieve the previous
parameters.
4.7 Settings
The Settings menu is for setting the control parameters for conductivity, pH and ORP.
4.7.1 Conductivity
Set point Type - A Set point is a setting at which the controller activates an output,
such as a solenoid valve or a metering pump on the relay outputs or dry contact
outputs. The type – Rising or Falling defines which side of the set-point the relay
activates. A Rising type means that the output activates when the input goes above
the set point. A Rising set point is commonly used in conductivity control where you
want to keep conductivity below a certain value. A Falling type activates the output
when the value goes below the set point.
Set point –This is the conductivity point where a bleed function will begin.
Differential – The differential setting controls when the bleed function stops. This
value subtracted from the conductivity set point causes the bleed function to stop.
Example: Rising Set point=1200, Differential=100, the bleed function begins when
the conductivity reaches 1200 and ends when the conductivity reaches 1100.
