DO9403T-R1 pH or mV transmitter, completely configurable, for use on the field 80x120x56,
output 4...20mA insulated with 2 wire passive or 4 wire active.
Power supply in active function 24Vac, on request 230Vac, in passive function 10...35Vdc.
The DO 9403T-R1 pH transmitter Indicator Monitor converts the output of a pH electrode, with temperature compensation, into a signal at 4
- 20 mA.
The pH electrode input circuit is galvanically insulated against the 4รท20 mA output signal.

Key functions.
PRG Programming of the parameters is activated by pressing the PRG key.
The symbol lights up on the display and the message P1 appears, indicating that the parameter
P1 is being programmed.
When the PRG key is pressed continuously, the messages P2, P3, P4, P5, P6, P7, P8, P9, P10 and the corresponding parameters are displayed in sequence.
After P10 the instrument returns to normal function.
After the parameter concerned gas been displayed, it is possible to view its value by pressing the OK key.
To change the parameter use the s and t keys.
Press the OK key again to confirm the value of the parameter.
SET Key for setting the relay intervention threshold.
The symbol and the REL symbol appear on the display,
fixed or flashing, indicating the switching on or
off threshold of relay A or of relay B.
C/°
F
- If this key is pressed it changes the temperature measuring unit to degrees
Celsius or degrees Fahrenheit.
- When pressed together with the CAL key it activates the manual temperature setting function.
- If pressed during the pH calibration function it quits the calibration function without storing the calibration.
pH/mV - If this key is pressed it changes the measuring unit to mV or pH.
- When pressed together with the CAL key it activates the pH calibration function.
OK Confirms the programming parameters, or the relay SET values, and stores them.
CAL
- When pressed together with the °
C/°
F key it activates the manual temperature setting function.
- When pressed together with the pH/mV key it activates the pH calibration function.
- Key used to confirm pH calibration and manual temperature setting.
s
- Key for increasing the value displayed in the parameter programming phase.
- During the relay SET point programming phase.
- During the calibration phase.
t
- Key for decreasing the value displayed in the parameter programming phase.
- During the relay SET point programming phase.
- During the calibration phase.
