Calibration Successful or Failed
If successful, touch Confirm to put the new calibration in memory. The calibration adjusts the water offset and
slope and displays the new slope and the mV in water at both measurement and reference wavelengths. If
failed, you may retry the calibration or cancel. Refer to Section 8 to troubleshoot a calibration failure.
Resume Control
Replace the sensor in the process and touch Confirm when ready to resume control.
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.
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.
Resume Control
Replace the sensor in the process and touch Confirm when ready to resume control.
Two Point Buffer Calibration
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
temperature compensation)
Enter the temperature of the buffer and touch Confirm.
First Buffer Value (does not appear if 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. 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 touching Confirm.
