PROGRAMMING THE TRANSMITTER
7a. For free chlorine, choose auto or manual pH correction. If you chose auto,
you must also configure the pH sensor. Go to step 7b. If you chose manual, go
to step 7k.
7b. Identify the location of the pre-amplifier for the pH sensor. Is it in the transmitter
(Xmtr) or in the sensor or junction box (Sensor/Jbox)?

399-09-62 Sensor/JBox
399VP-09 Sensor/JBox
399-14 Xmtr
7c. Select a maximum value for the pH sensor reference offset.
7d. Activate diagnostic messages. Even if diagnostic messages are turned off, the
current pulses used to measure diagnostics will still be operating.
7e. Turn on or turn off the temperature correction for the glass membrane imped-
ance measurement. Keeping the temperature correction on is recommended.
7f. Select a value at which the low glass impedance fault message will be shown.
The default value is 0010 MΩ.
7g. Select a value at which the high glass impedance fault message will be shown.
The default value is 1000 MΩ.
7h. Enter the time constant for the input filter.
7i. Choose single or dual slope calibration. For the vast majority of applications,
dual slope calibration is unnecessary.
7j. To return to the main display, press MENU then EXIT.
7k. If you choose manual pH correction, enter the desired pH. The transmitter will
use this value in all subsequent calculations no matter what the true pH is.
7l. Enter the time constant for the input filter.
7m. Choose single or dual slope calibration. For the vast majority of applications,
dual slope calibration is unnecessary.
7n. To return to the main display, press MENU then EXIT.
