6.4.5 Procedure-Standardization

1.The pH value measured by the analyzer can be changed to match the reading from a second or referee instrument. The process of making the two readings agree is called standardization.

2.Place the sensor in the flow cell. Wait until pH readings are stable.

Calibrate?

Output 2

3.Press MENU. The main menu screen appears. The cursor will be on Calibrate. Press ENTER.

4.Choose the sensor you wish to calibrate. Sensor 1 is the chlorine sensor. Sensor 2 is the pH sensor.

0 7.00 pH

7.Once reading is stable, measure the pH of the liquid using a referee instrument. Because the pH of many natural and treated waters depends on temperature, measure the pH of the sample immediately after taking it. For poorly buffered samples determine the pH of a continuously flowing sample from a point as close as possible to the sensor.

Change the reading to match the reading of the referee instrument.

Offset:

2 mV

8.If the calibration is successful, the screen at left will be displayed for five seconds. The display will then return to screen in step 3.

If the calibration is not successful, the existing calibration data will not be changed. A screen will appear identifying the error (high slope, low slope, or offset error). For troubleshooting see section 9.5.

9. To return to the main display, press MENU then EXIT.
