Operation

5.7 ORP Calibration

5.7.1 One-point Manual Calibration

The manufacturer offers a one point manual calibration for ORP. The value of the sample used in the manual calibration may be determined by laboratory analysis or comparison reading.

1.From the Main Menu, select SENSOR SETUP and confirm.

2.Select the appropriate sensor if more than one is attached and confirm.

3.Select CALIBRATE and confirm.

4.Select 1 POINT MANUAL CAL. Select the available Output Mode (Active, Hold, or Transfer) from the list box and confirm.

5.Move the clean probe to Solution and confirm.

6.Confirm when stable. Edit the solution value using the keypad and confirm.

7.A screen will display 1 Point Manual Complete and the slope (XX.X mV).

8.Return the probe to process.

5.8Concurrent Calibration of Two Sensors for pH and ORP

1.Begin a calibration on the first sensor and continue until “Wait to Stabilize” is displayed.

2.Select LEAVE and confirm. The display will return to the main measurement screen. The reading for the sensor currently being calibrated will flash.

3.Begin the calibration for the second sensor and continue until “Wait to Stabilize” is displayed.

4.Select LEAVE and confirm. The display will return to the main measurement screen and the reading for both sensors will flash. The calibration for both sensors are now running in the background.

5.To return to the calibration of either sensor select SENSOR SETUP from the Main Menu and confirm. Select the appropriate sensor and confirm.

6.The calibration in progress will be displayed. Continue with the calibration.
