4-20 mA analog output, offset and span configurable for the pH or DO display. The model 6309PDTF comes with a RS485 interface which can easily let the user log all data (from multiple model 6309 or 6308) with an PC.
Warning: If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. B. Cleaning The Meter 1. Be sure to remove the power before attempting to clean the meter. 2.

3. CURRENT OUT- 4. H, L- This will display the actual output of the 4-20 One or both of these annunciators will be mA output. At POWER-ON this will show displayed if the left side reading (LARGE “OFF” for about three seconds before going FONT DISPLAY) triggered the respective to normal operation.
B. Operational Keys Description Figure 2 Description MODE- In the measure mode, this key will change the DO display to DO % or DO ppm. In the Calibration/Setting mode this key will move to the next digit of the current active parameter.
ON once the user plugs in the power cord to an AC power supply. 1. Connect the AC line to the rear of the meter. The model 6309PDTF can be used with 115 or 230 VAC 50/60 Hz. Power consumption is 6 watts. Make sure the EARTH connector is connected to the earth lead of the AC power line.
After the self-diagnostic is complete, the temperature reading will be displayed on the lowest part of the screen and the user is ready to make DO or pH measurements. MODEL 6309PDTF MODES A. Measure Mode Turning ON the unit will always display in the measure mode.

The position of pH and DO display can be switched depending on the selected analog output on the Current out setting page of the Calibration/Setting mode. (See Calibration/Setting Mode) This meter is designed to provide 4 distinct measurements: 1. Temperature Current temperature of the solution, which is always displayed.
B. Calibration/Setting Mode Pressing the “CAL/VIEW” key for about two seconds during the measure mode will bring- up the first page of eight pages of the Calibration/Setting mode. Pressing “CAL/VIEW” key will switch to the next page. At the last page, press “CAL/VIEW” key again will return the user to measure mode.

warning, telling the user that all relays are frozen and that the user can calibrate and change the settings. [NOTE: FROZEN means all the relays and the analog out will maintain their last status until the user returns to normal display mode.] 3.

” icon will appear. Pressing the “ENTER” key will start the DO calibration. The unit of this calibration will depend on the unit of DO at the measure mode. To accurately calibrate the model 6309PDTF, the user will need the following information: i) The approximate atmospheric pressure (in mbar) of the region in which the dissolved oxygen measurements will be taken.
3) Wait around 2 hours for the dissolved oxygen and temperature readings to stabilize. Pressing the “ENTER” key will start the calibration. 4) If the user is calibrating in “%” then the 100% calibration will be displayed. An error will be displayed if the input is not within the normal DO range.
Use “UP” and “DOWN” to change the RELAY 4 type then press “ENTER” key to save. After selecting the RELAY 4 type, the user can now select the RELAY 4 setting. Use “UP” and “DOWN” keys to change the blinking digit. Use the “MODE” key to select another digit and the “ENTER”...

2) RS485-RTU ID – This is the unique ID/Address for the unit. If the user is connecting multiple model 6309PDTF or other Jenco models for logging purposes then this ID/Address must be unique for each connected unit. This ID/Address is the same address that must be used by the PC program to communicate with this unit.
C. Relay Action, Relay Setpoint, Hysteresis Mode & Hysteresis Value If the relay control type is set to HI and the hysteresis mode is CENTER, the relay will turn ON at [(RELAY SETPOINT) + (0.5 * hysteresis value)], and will turn OFF at [(RELAY SETPOINT) - (0.5 * hysteresis value)].
Figure 4 [Note : Setting any hysteresis value to zero may cause jitter and possibly damage the relay(s).] D. pH Relays There are two independent relay channels for pH display, which have independent set point and HIGH or LOW control type (see Figure 4.). The hysteresis mode (center or edge, see Figure 4.) and hysteresis value will be used by both pH relays.
The action of the pH relays is dependent on set point, relay control type (HIGH or LOW), hysteresis mode (Center or Edge), hysteresis value and the current pH display (See figure [Note: The user can set the RELAY 1 and RELAY 2 from 0.00 to 19.99 pH, but be reminded that the range of pH is –2.00 to 16.00 pH.] E.
C. pH Linear Output The analog output will produce a linear analog output if the user selects this option (see figure 5). The analog output will be dependent on the pH_4 mA setting, pH_20 mA setting and the current pH display. pH antilog output pH linear output Figure 5...
The DO linear analog output is based on the following equation: = 4 mA+(16 mA) * (D - DO (4)) / (DO (20) - DO (4)) (DO) (DO) Where: = analog output (DO) = current DO display (DO) DO(4) = DO user setting for 4 mA DO(20) = DO user setting for 20 mA.
