ELECTRICAL CONNECTIONS For correct electrical connections always refer to the rear panel pad printing, specific for each model. The above figure represents the pH/RX model version. The difference among different models is the input signal terminal block (pins 20 to 23), while the remaining connections are the same for all models. -

P02 (conductivity) TEMP. COMPENSATION COEFFICIENT αT S507 performs the temperature compensation accordingly with the following equation: αT C(t) = C(tref) * 1 + ─── * (t – tref) where: t = measured (or set) temperature, °C tref = reference temperature, °C (typically set at 25°C, parameter P03) αT = temperature compensation coefficient, %/°C (parameter P02)

ERRORS When an error is detected (including START/STOP key pressed), the LED ON starts blinking, the mA output provides the fault current value set in P21, and the display shows the corresponding error message, as listed here below: WARNING 1 - RELAY K1 DISABLED No working mode has been configured for K1 output, but the instrument works normally. -
Page 20: Ph Input Specifications
pH INPUT SPECIFICATIONS ELECTRICAL CONNECTIONS FOR pH-METER The signal comes from the electrode through a coaxial cable, with maximum recommended length of 20 meters (for longer cables, please contact the manufacturer). The electrode input is on removable terminal block: connect the coaxial cable core to terminal 22, and the shield to terminal 23 (Note: remove any black conductive plastic between the core and shield of the cable). -
Page 21: Redox Input Specifications
Note: If you attempt to calibrate the offset at a pH value too different from pH 7, or to calibrate the gain with a buffer solution too close to pH neutrality, the instrument shows the “CALIBRATION ERROR!” message and does not save the calibration data.

Page 24: Calibration Of The Cell
CALIBRATION OF THE CELL To calibrate the cell, a colorimeter for measuring the chlorine concentration in aqueous solutions is needed (with DPD1 method). If the electrochemical calibration is also required, a carbon filter is needed. Run instrument and cell for at least 6 hours with chlorinated water, containing an average chlorine working concentration. -
Page 25: Conductivity / Resistivity Input Specifications
CONDUCTIVITY / RESISTIVITY INPUT SPECIFICATIONS ADDITIONAL TECHNICAL INFO The electronic precision of the conductivity measurements is better than 1%, and the repeatability is better than 0.2% FS, without temperature compensation (resistive calibration). The temperature compensation introduces an additional error of 0.3% FS and is performed through the PT100 input. The temperature sensor may be a probe separated from the conductivity cell (e.g. -
Page 26: Electrochemical Calibration Of Conductivity Meter
ELECTROCHEMICAL CALIBRATION OF CONDUCTIVITY METER The electrochemical calibration allows to compensate errors due to the cell-instrument connection cable and to the mechanical error of the cell constant. If the temperature compensation feature is used, immerse the Pt100 sensor into the solution close to the cell, or anyway at the same temperature. -
