Option Description
Hold The sensor output value is held at the current measured value during the calibration procedure.
Transfer A preset output value is sent during calibration. Refer to the controller user manual to change the
preset value.
7. With the sensor in the first reference solution, push ENTER.
The measured value is shown.
8. Wait for the value to stabilize and push ENTER.
Note: The screen may advance to the next step automatically.
9. If the reference solution is a sample, measure the pH value with a secondary verification
instrument. Use the arrow keys to enter the measured value and push ENTER.
Note: If a pH buffer not listed the Cal Options menu is used, refer to the buffer bottle to find the pH value that
corresponds to the temperature of the buffer.
10. For a 2-point calibration, measure the second reference solution (or sample):
a. Remove the sensor from the first solution and rinse with clean water.
b. Put the sensor in the next reference solution and push ENTER.
c. Wait for the value to stabilize. Push ENTER.
Note: The screen may advance to the next step automatically.
d. If the reference solution is a sample, measure the pH value with a secondary verification
instrument. Use the arrow keys to enter the measured value and push ENTER.
11. Review the calibration result:
• Passed—the sensor is calibrated and ready to measure samples. The slope and/or offset
values are shown.
• Failed—the calibration slope or offset is outside of accepted limits. Repeat the calibration with
fresh reference solutions.
12. If the calibration passed, push ENTER to continue.
13. If the option for operator ID is set to Yes in the Calibration Options menu, enter an operator ID.
Refer to Change calibration options
14. On the New Sensor screen, select whether the sensor is new:
Option Description
Yes The sensor was not calibrated previously with this controller. The days of operation and previous
calibration curves for the sensor are reset.
No The sensor was calibrated previously with this controller.
15. Return the sensor to the process and push ENTER.
The output signal returns to the active state and the measured sample value is shown on the
measure screen.
Note: If the output mode is set to hold or transfer, select the delay time when the outputs return to the active
state.
