5.1 Alarms Menu
If there is a red icon with a number in it in the upper right corner of the screen, there are that many active alarms.
Touch the icon to view a list of active alarms. If there are more than four active alarms, scroll up or down to see the
next page. A yellow rectangle on the lower right will indicate if there is more than one page and the current position in
the pages.
Touch the Home icon to go back to the previous screen.
5.2 Inputs Menu
Touch the Inputs icon to view a list of all sensor and digital inputs. Swipe up and down the list of inputs, A yellow
rectangle on the lower right will indicate if there is more than one page and the current position in the pages.
Touch the input to access that input’s details, calibration (if applicable) and settings.
Sensor Input Details
The details for any type of sensor input include the current value read, alarms, the raw (uncalibrated) signal, the sensor
type, the 24-hour minimum, maximum and average values, and the calibration gain and offset and date of last cali
-
bration. If the sensor has automatic temperature compensation, then the sensor’s temperature value and alarms, the
temperature resistance value read, and the type of temperature element required are also displayed under a separate
sensor input menu.
Calibration
Touch the Calibration icon to calibrate the sensor. Select the calibration to perform: One Point Process, One Point
Buffer or Two Point Buffer Calibration. Not all calibration options are available for all types of sensor.
One Point Process Calibration
New Value
Enter the actual value of the process as determined by another meter or laboratory analysis and touch Confirm.
Cal Successful or Failed
If successful, touch Confirm to put the new calibration in memory.
If failed, you may retry the calibration or cancel. Refer to Section 8 to troubleshoot a calibration failure.
One Point Buffer Calibration, Disinfection/Generic Sensor Zero Cal, Conductivity Air Cal
Cal Disables Control
Touch Confirm to continue or Cancel to abort
Buffer Temperature
(only appears if no temperature sensor is detected for sensor types that use automatic tem-
perature compensation)
Enter the temperature of the buffer and touch Confirm.
Buffer Value
(only appears for One Point Calibration except when automatic buffer recognition is used))
Enter the value of the buffer being used
Rinse Sensor
Remove the sensor from the process, rinse it off, and place it in the buffer solution (or oxidizer-free water for
Zero Cal, or air for the conductivity open air cal). Touch Confirm when ready.
Stabilization
When the temperature (if applicable) and signal from the sensor is stable, the controller will automatically move
to the next step. If they don’t stabilize you may manually go to the next step by pressing Confirm.
