12. If not using the optional zero calibration cartridge 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.
8.2.4 Calibration with the process sample
The sensor can remain in the process sample.
1. Push the menu key and select SENSOR SETUP>CALIBRATE.
2. If the pass code is enabled in the security menu for the controller, enter the pass code.
3. Select SAMPLE CAL and push enter .
4. Select the option for the output signal during calibration:
Option Description
ACTIVE The instrument sends the current measured output value during the calibration
procedure.
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.
5. With the sensor in the process sample, push enter . The measured value is shown. Wait for the
value to stabilize and push enter .
6. With a certified secondary verification instrument measure the concentration value of the sample.
To avoid impurities in the sample take the measurement before the sample enters the flow
chamber. Use the arrow keys to enter this value if different from the value displayed and push
enter .
7. Review the calibration result:
• PASS—the sensor is calibrated and the calibration factor is displayed.
• FAIL—the calibration is outside of accepted limits. Clean the sensor and retry. Refer to
Troubleshooting on page 23 for more information.
8. If the calibration passed, push enter to continue.
9. If the option for operator ID is set to YES in the CAL OPTIONS menu, enter an operator ID. Refer
to
Change calibration options on page 22.
10. 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.
11. With the sensor still in the process 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.
8.2.5 Change calibration options
The user can set a calibration reminder or include an operator ID with calibration data from this
menu.
1. Push the menu key and select SENSOR SETUP>CALIBRATE.
2. If the pass code is enabled in the security menu for the controller, enter the pass code.
