At the end of the calibration, the display will tell you if the calibration was successful or if the
calibration failed. If successful, press the Enter key after the electrode has been replaced into the
sample stream to resume control. If failed, refer to Section 8 for troubleshooting help. The
calculated slope being more than 80% different from theoretical causes a calibration failure, or by
the pH 7 mV offset being more than 60 mV.
1 pt Buffer Cal
Step 1 will explain that control is suspended during the calibration procedure. Press the Enter key
when the cursor is on “Continue” to start the calibration. To cancel the calibration, press the Next
key to move the cursor to “Cancel”, then press the Enter key.
Step 2 will ask you to enter the temperature of the buffer solution. Use the Arrow keys to change
the value of the temperature, then press the Enter key to continue.
Step 3 will prompt you to rinse the electrode, and place it into the buffer solution. Press the Enter
key to continue.
Step 4 will ask you to enter the value of the buffer solution. Use the Arrow keys to change the
value, then press the Enter key to continue.
Step 5 will display the mV output of the electrode in the buffer. When this reading is stable, press
the Enter key to continue.
At the end of the calibration, the display will tell you if the calibration was successful or if the
calibration failed. If successful, press the Enter key after the electrode has been replaced into the
sample stream to resume control. If failed, refer to Section 8 for troubleshooting help. The
calculated slope being more than 80% different from theoretical causes a calibration failure, or by
the pH 7 mV offset being more than 60 mV.
1 pt Process Cal
Step 1 will display the current pH reading of the system water. Below that, use the Arrow keys to
fill in the new value, then press the Enter key to continue.
At the end of the calibration, the display will tell you if the calibration was successful or if the
calibration failed. If successful, press the Enter key after the electrode has been replaced into the
sample stream to resume control. If failed, refer to Section 8 for troubleshooting help. The
calculated slope being more than 80% different from theoretical causes a calibration failure, or by
the pH 7 mV offset being more than 60 mV.
ORP Calibration
2 pt Buffer Cal
Step 1 will explain that control is suspended during the calibration procedure. Press the Enter key
when the cursor is on “Continue” to start the calibration. To cancel the calibration, press the Next
key to move the cursor to “Cancel”, then press the Enter key.
Step 2 will prompt you to rinse the electrode, and place it into the first buffer solution. Press the
Enter key to continue.
Step 3 will ask you to enter the value of the first buffer solution. Use the Arrow keys to change the
value, then press the Enter key to highlight ‘CONTINUE’, then press Enter again to put the value
into memory.
