Connections
pH/mV/O2 electrode
Both channels are provided with floating inputs. The maximum common mode
voltage (potential between the (-) terminals of CHAN.1 and CHAN.2) should not
exceed ±1 V. Connect the internal wire of the electrode cable to terminal (+) and
the screening of the cable to terminal (-) of (CHAN1 or CHAN2). Ground loops can
be avoided by immersing an earthing rod in the process liquid close to the elec-
trodes. Connect it only to terminal (M)!
Temperature probe
A separate automatic temperature compensation is provided for each channel but
a common Pt1000 (or Pt100) thermocompensator for both channels can also be
used. Connect the internal wire of the electrode cable to terminal (+) and the
screening of the cable to terminal (-) of (C1 or C2).
Recorder
Two recorders, one for each channel, can be connected to the (+) and (-) terminals
of (OUT1) and (OUT2). Max. impedance = 300 Ω.
Relays
There are three (R315) or four (R305) relays (REL1...REL4) with voltage-free con-
tacts. Connect their two contacts in series with the load. The ratings of the con-
nected load should lie between 12...250 V~, maximum 0.5 A.
Mains
Connect phase to terminal (P), neutral to terminal (N), and earth to earthing
terminal.
• Always short circuit the unused pH/mV/O2
input terminals!
• Special care should be taken when con-
necting a typical pH/mV/O2 coaxial cable.
Make sure that all parts are dry and clean
and do not forget to remove the black
antistatic foil between the inner lead and
the outer screening!
RS485
Only use twisted pair UTP cable to connect up to 31 controllers to a computer!

Sample point
Before the exact location of the electrodes is finalised, it is worthwhile to carry
out a measuring profile of the process stream to ensure that the required homo-
geneity is being achieved. As a general rule the electrodes should protrude into
the process stream by one-third of the pipe width and be positioned so as to avoid
gas pockets or sediments.
Generally the measuring electrodes are inserted into the flow with the sample
pick-up facing downstream in order to reduce the risk of blockage by suspended
material.
All sensors are usually positioned vertically at a suitable point downstream of the
dosing point, where the measurements are stable and reliable. The response of
the dosing system will be affected by the time required to disperse the reagents
and their arrival at the measuring point.

(R305) Measurements
1. Should you want to recalibrate, select the desired measurement and press
CAL. Follow the instructions on the screen. The displayed possibilities depend
on the channel set-up and selected measurement.
pH calibration:
2. Select the proper buffer from one of the values in memory or enter manually
a special value and press CAL. The unused buffers should be switched off.
3. Remove the electrodes from their fittings, rinse them with distilled water and
immerse them in the first buffer solution. Select [CALIBRATE], press CAL and
follow the instructions on the screen until the calibration is finished.
4. After rinsing the electrodes with distilled water, insert them back in their fit-
tings and start the control.
mV calibration:
2. Remove the electrodes from their fittings, rinse them with distilled water,
immerse them in a standard solution of known potential, adjust to the proper
value and press CAL.
3. After rinsing the electrodes with distilled water, insert them back in their fit-
tings and start the control.
Oxygen calibration:
2. The display shows the salinity correction. Select the proper values and press
CAL. Leave salinity correction to zero unless you are going to measure in
heavily salted solutions such as e.g. sea-water (35 g/l). Select [CALIBRATE],
press CAL and follow the instructions on the screen until the calibration is
finished.
3. Remove the electrode from its fitting and rinse it with distilled water. The
electrode exposed to the air reaches an equilibrium corresponding to the par-
tial pressure of oxygen and thus to saturation in water at the given tempera-
ture. The instrument shows the measured saturation, current, temperature,
and will calibrate automatically when readings are stable.
4. After rinsing the electrode with distilled water, insert it back in its fitting and
start the control. Stirring the solution during the measurements promotes the
homogeneity and is obligatory! The advection rate must be at least 10 cm/s.
Temperature calibration:
1. Without Pt1000, adjust the manual temperature compensation and proceed by
pressing SET. Should you want to recalibrate, press CAL.
2. Immerse the Pt1000 in a standard solution of known temperature. Calibrate to
the proper value and press CAL.
Adjustment:
2. Measure the real value of the processed liquid with an other electrode and
meter. Adjust to the real value and press CAL. Press STOP here if you wish to
return to the original readings.
• A blinking decimal point warns you for unstable measurements. Wait to read
the display!
• Stirring the solution during the measurements promotes the homogeneity and
is therefore always recommended.
• Press é to maximum measurement.
• Press ê to minimum measurement.
• Press STOP to stop the control without interrupting the measurements.

R305 • R315 10 / 42
(R315) Measurements
1. Should you want to recalibrate, select the desired measurement and press
CAL. Follow the instructions on the screen. The displayed possibilities depend
on the channel set-up and selected measurement.
Capacitive compensation:
2. Capacitive compensation increases accuracy in the very low conductivity
ranges (<10 µS/cm). Select whether this compensation should be applied or
not. Verify if the attached electrode is completely dry. Select [COMP.ON] or
[COMP.OFF] and press CAL. Follow the instructions on the screen.
Conductivity calibration:
2. Select the proper standard from one of the values in memory or enter manu-
ally a special value and press CAL. Also select the temperature to which all
future measurements will be referred to.
3. Remove the electrode from its fitting.
4. After rinsing the electrode several times with the standard solution, immerse
it in that standard. The solution temperature is not so critical but should lie
between 0°C and 30°C. Select [CALIBRATE], press CAL and follow the instruc-
tions on the screen until the calibration is finished.
5. After rinsing the electrode with distilled water, insert it back in its fitting and
start the control.
Temperature calibration:
2. Without Pt1000, adjust the manual temperature compensation and proceed by
pressing SET. Should you want to recalibrate, press CAL.
3. Immerse the Pt1000 in a standard solution of known temperature. Calibrate to
the proper value and press CAL.
Adjustment:
2. Measure the real value of the processed liquid with an other electrode and
meter. Adjust to the real value and press CAL. Press STOP here if you wish to
return to the original readings.
• A blinking decimal point warns you for unstable measurements. Wait to read
the display!
• Stirring the solution during the measurements promotes the homogeneity and
is therefore always recommended.
• Press é to maximum measurement.
• Press ê to minimum measurement.
• Press STOP to stop the control without interrupting the measurements.
