5.2.2pH Probe Programming

1.From the Main Menu, select OPTIONS>ADVANCED OPTIONS>DATALOG.

2.Highlight Select Inputs using the UP and DOWN keys and press SELECT.

3.Highlight pH using the UP and DOWN keys, then press SELECT.

4.Press the CHANGE CHOICE key to cycle between Logged and Not Logged, then press ACCEPT.

5.Enter a logging interval, then press ACCEPT. Valid logging intervals are shown on the status bar along the bottom edge of the display.

6.Select another channel to configure or press RETURN to back up one step. Press MAIN MENU to return to the Main Menu display.

5.2.3pH Probe Calibration

Calibrate the pH probe after the pH probe is connected and programmed. Calibrating the pH probe requires a thermometer and any two of the following buffer solutions: 4, 7, or 10 pH.

The pH probe is an application sensitive device. When used in harsh environments, the accuracy and life expectancy of pH probes can decrease.
