10 2 Description General The instrument has two analog inputs and one binary input. The first analog input is suitable f connecting standard signals (0-10 V 0(4) - 20 ma), which can be prepared by any transmitter sens (such as a 2-wire transmitter). Pt100, Pt1000 NTC/PTC resistance thermometers (up to 4 k ohms) can be connected to the second analog input. The power supply f a 2-wire transmitter is integrated in the instrument. Input signals can be shown as numbers as a bar graph on the graphic display. Parameters are displayed in plain text f easily comprehensible and secure operation. With two optional relay switching contacts, it is possible to implement both simple switching alarm functions and demanding control tasks with P, PI, PD and PID action. If required, the instrument can also be provided with two freely configurable and scalable analog outputs (0-10 V 0(4) - 20 ma). The instrument is suitable, f example, f displaying, measuring and controlling: - Free chline, chline dioxide, ozone, hydrogen peroxide and peracetic acid, in combination with senss as per data sheet The ph value redox potential with 2-wire transmitters as per data sheet (Hydrostatic) liquid levels with 2-wire transmitters (level probes) as per data sheet data sheet Flow rate in conjunction with transmitters as per data sheet Two temperature measuring points. - Most senss and transmitters that output standard signals (0-10 V 0(4) - 20 ma). Because temperature measurement is integrated, temperature compensation takes place quickly and precisely, which is particularly imptant f many analytical measurements. Key features Display: ph, ms/cm, µs/cm, ppm, %, mv, etc. Special visualizations can also be configured with the setup program. Large, backlit LC graphic display. A choice of display visualizations: large numbers, bar graph trend display. Integrated calibration routines. Calibration logbook. IP67 enclosure protection f surface mounting IP65 enclosure protection f switch cabinet mounting Selectable languages: German, English, French; additional languages can be loaded later through the setup program. Through the setup program: user-friendly configuration, system documentation, subsequent loading of additional languages. 10

19 5 Installation 5.1 Installation instructions The electrical connection must only be perfmed by qualified personnel! Conduct cross-sections and ferrules The choice of cable, the installation and the electrical connection must confm to the requirements of VDE 0100 Regulations on the Installation of Power Circuits with Nominal Voltages below 1000 V and the appropriate local regulations If contact with live parts is possible when wking on the device, it must be completely disconnected from the electrical supply. The load circuits must be fused f the maximum load currents in each case to prevent the relay contacts becoming welded in the event of a sht circuit. Electromagnetic compatibility meets the requirements of EN 61326, Lay the input, output, and supply lines so they are physically separated from each other and are not parallel. Use twisted and shielded probe cables. If possible, do not lay these cables close to components cables through which current is flowing. Ground the shielding at one end. The probe cables must have an uninterrupted run (do not route them via terminal blocks similar arrangements). No other consumers can be connected to the power terminals of the instrument. The instrument is not suitable f installation in areas with an explosion hazard. Apart from faulty installation, increct settings on the instrument may also affect the proper functioning of the subsequent process lead to damage. You should therefe always provide safety equipment that is independent of the instrument and it should only be possible f qualified personnel to make settings.

96 11 Calibrating conductive conductivity cells 11.1 Notes During calibration, relays and analog output signals adopt their configured states! The senss connected to the instrument should be cleaned and the instrument itself calibrated, at regular intervals (subject to the measuring material) General Requirement Start calibration A conductive conductivity cell delivers a standard signal to the JUMO AQUIS 500 AS either via an external transmitter provided by the customer via a transmitter integrated in the measuring cell. If the signal is not yet temperature compensated, if there are measurement errs because of cell constant deviations, the JUMO AQUIS 500 can take on the task of temperature compensation and/ cell calibration. The instrument provides two calibration options f adapting the JUMO AQUIS 500 AS to conductive conductivity cells: - Calibration of the relative cell constants; this is a one-point calibration, see section 11.3 "Calibrating the relative cell constant", page Calibration of a linear temperature coefficient; this is a two-point calibration, see section 11.4 "Calibrating the temperature coefficient of the measurement solution", page Calibration of a non-linear temperature coefficient. Here the temperature coefficient is calibrated at six points, see section 11.4 "Calibrating the temperature coefficient of the measurement solution", page 99. Calibration can be started as follows: - By pressing the CAL key, if this has been enabled in ADMINISTR. LEVEL / PASSWORD / CALIB. ENABLE. - Via ADMINISTR. LEVEL / PASSWORD / CALIB.

The max./min. value memy can be reset: Operat level / Display / Max./min. value memy / Yes, See "Operat level parameters" page 110ff. Conductivity temperature compensation The conductivity of a measurement solution is temperature-dependent (the conductivity of a solution rises as the temperature increases). The dependency of conductivity and temperature describes the temperature coefficient of the measurement solution. As conductivity is not always measured f the reference temperature, automatic temperature compensation is integrated in this instrument. The transmitter uses the temperature coefficient to calculate the conductivity that would exist f a reference temperature from the current conductivity and the current temperature. This is then displayed. This process is called temperature compensation. Modern transmitters offer different ways to perfm this temperature compensation. - Linear compensation (constant temperature coefficient). This type of compensation can be applied to many kinds of nmal water, with acceptable accuracy. The temperature coefficient used is then approx. 2.2%/ C - See below f non-linear compensation. - Natural water (EN27888 ISO 7888). In this case, so-called non-linear temperature compensation is used. Accding to the standard cited above, the relevant type of compensation can be applied to natural groundwater, spring water and surface water. The definition range f the water temperature looks like this 0 C T < 36 C. 123

125 15 Appendix Temperature compensation with the temp. coef. curve The relevant temperature coefficient is determined from the temp. coef. curve by means of the current temperature of the medium. Intermediate values, such as ( x at T x ) between the two ascertained values ( 3 at T 3 ) and ( 4 at T 4 ) are linearly approximated. As with linear temperature compensation, the compensated measurement value is calculated with the ascertained TC. If the measured temperature is lower than the temperature at the beginning, the first TC is used f compensation. If the measured temperature is higher than the temperature at the end, the last TC is used f compensation. γ ( komp) = γ ( mess) α ( x 1+ (Tx - T Ref. ) 100 * ) Sequence of automatic calibration The temp. coef. curve is automatically applied in a temperature range specified by the user. The temperature range from beginning to end is divided into 5 segments of equal size. The temperature range must be greater than 20 Kelvin and must overlap the reference temperature. Example: Reference temperature 25 C, temperature at beginning 18 C and temperature at end 50 C. Concentration measurement The instrument can calculate the concentration of different measuring materials from the current measurement values of uncompensated conductivity and temperature. Choice of concentration calculations: NaOH (caustic soda) - Range 1: 0-15 wt.% - Range 2: wt.% HNO 3 (nitric acid) - Range 1: 0-25 wt.% - Range 2: wt.% H 2 SO 4 (sulphuric acid) - Range 1: 0-28 wt.% - Range 2: wt.% - Range 3: wt.% 125
