1. INTRODUCTION
1.1. APPLICATION
The AnaCONT compact transmitters, liquid analytical instruments are suitable for high precision measurement and transmission of acidity or alkalinity - pH (Hydrogen ion concentration) value -, reducing and oxidizing capability - ORP (Oxidation Reduction Potential) value -, or Dissolved Oxygen content of process water, wastewater, surface water, ground water and drinking water. These measurements can be widely used in industrial practice and could be of great relevance. In the field of environmental protection or sewage treatment, instruments like that are suitable for measuring the concentration of hazardous substances (chromium, cyanide). In chemical- and pharmaceutical industry, high precision measurement has utmost importance in the aspect of the technology (e.g. solvent feed), in many cases it is quality specification standard.
1.2. OPERATION PRINCIPLE
The intelligent signal processing of the electronics calculates the output signal from the voltage output values of the electrode and the temperature probe, and compensates it to 25°C. This value composes the basis of all output signals of the instrument.
1.2.1. Characteristics of an ideal pH electrode
he pH electrode immersed into the measured liquid measures a voltage value which is proportional to the hydrogen
ion concentration of the liquid.
0mV output at neutral pH value (pH=7.00) Positive voltage output in acidic liquids (pH<7) Negative voltage output in alkaline liquids (pH>7) Total measuring range is 0-14pH -59.16mV/pH (Nernst potential) slope at 25 °C
 The temperature dependency of the Nernst potential is -0.001984 mV / °C.

Because the pH electrodes in deed are not ideal (their properties depend on the design of the electrode, manufacturing tolerances and most of all the age of the electrode) the parameters differ from the given values above. To achieve reliable pH measurement and accuracy these electrodes must be calibrated from time to time. The time interval between two calibrations depends on the application conditions where the pH probes are used. Calibration of pH electrodes means offsetting the displayed value (7.00pH) when gauging neutral buffer solution, and adjusting the slope (pH/mV) by measuring buffer solutions with other pH value (usually with 4.00pH and 10.00pH value) by adjusting the displayed value to exact 4.00 and 10.00pH, respectively.

1.2.2. Characteristics of an ideal ORP electrode
Negative voltage output in liquids with reduction potential, Positive voltage output in liquids with oxidation potential, Output voltage is equal to the redox potential (according to the Nernst equation) pH independent measurement with certain types
To achieve reliable measurement and accuracy, these electrodes have to be thoroughly checked before installation and during usage from time to time. The time interval between two calibrations depends on the application and conditions where the ORP probes are used.
1.2.3. Characteristics of an ideal DO sensor
The dissolved oxygen level indicates the amount (in mg/l or ppm) of physically dissolved gas-form oxygen in liquid phase. Oxygen-permeable membrane amperometric DC sensor wetted in the measurement medium gives output
urrent proportional to the dissolved oxygen concentration of the medium.

The ideal DO sensor has:

Temperature independent output current
Real DO sensor gives off a minimal I

0ppm current in case of 0 ppm dissolved oxygen concentration and its oxygen-permeable capability is temperature­dependent. Oxygen-permeable capability of the membrane is increasing according to the increase of the temperature, at 25 °C it can be 4%/°C. Temperature proportional correction is necessary for reliable measurement.
The DO sensors in deed are not ideal (their properties depend on the design of the electrode, manufacturing tolerances and most of all the age of the electrode), so the parameters differ from the given values above. To give reliable DO measurement and accuracy these electrodes must be calibrated from time to time. In case of DO sensors the calibration means that 0 ppm output value have to be set by offsetting in an oxygen-free solution. For DO measurement of other mediums (for example dry air 20.95%@25°C or oxygen-saturated water) adjustment of slope (nA/ppm) has to done accurately according to the properties of these mediums.

4. MAINTENANCE AND REAPAIR
The AnaCONT series do not require maintenance on a regular basis, but the electrode (depending on the application) may need to be checked, cleaned, calibrated and replaced regularly. Repairs during or after the warranty period are carried out exclusively at the Manufacturer’s. Equipments sent back for repairs should be cleaned or neutralised (disinfected) by the User.
All sensors and electrodes including the NIVELCO recommended ones need proper storage, handling and calibration to have long life-time and give reliable measurement. Improper handling and lack of calibration will lead to unreliable measurement
4.1. STORAGE
DO sensors can be stored (under normal storage conditions) for a period of 12 month without shortening its lifecycle. The lifetime of pH and ORP electrodes is maximum one year (storage + usage). Prominent ships the electrodes hydrated in a well sealed container with a 3mol/l KCl solution in it. As a result, the membrane remains wet and the electrode is in ready-to-use state. It is important to keep these containers as they are needed for storing the electrodes during calibration or in case of transportation. If for any reason the electrodes are taken out of the process they must be put back into the storage containers containing storage liquid.
Notes: Never let the membrane and the diaphragm desiccated. Do not leave the electrode on open air longer than 10 minutes. If the electrode is warm it can desiccate even within a shorter period of time!
4.2. PERIODIC SETTING, CALIBRATION AND VERIFICATION
The electrode is exposed to different stresses, dependent on the measured medium, its ORP and pH value and the medium temperature. That is why the electrode needs to be recalibrated (its accuracy needs to be checked) between certain time intervals depending on the application utilizations. The calibration intervals may vary from few days to several weeks (max. 8 weeks).
24 / 60  le00100a0600p_05  BKI 11 ATEX 0012 X
4.2.1. Periodic calibration of the pH electrode
The calibration has to be done minimum in two measuring points (using two different buffer solutions). The calibration points have to be selected so that the widest measuring range is covered. The common calibration points are 4.00pH and 10.00pH, 4.00pH and 7.00pH, 7.00pH and 10.00pH, or even more points for example
4.00pH, 7.00pH and 10.00pH. Recommended solutions:

4.2.2. Verification of the ORP electrode
The calibration can be done (for example) with a 465 mV buffer solution. After the electrode is rinsed with distilled water put the electrode into the buffer solution. The electrode should reach the correct measurement value in 30 seconds. If the measured value is less with more than (the acceptable) 20mV the electrode should be cleaned. If the electrode does not give the desired measurement after cleaning it has to be replaced

The given (mV) values refer to 25°C. The temperature dependency is given by the manufacturer, usually in a table on the label of the bottle.
4.2.3. Periodic calibration of the DO sensor
The calibration has to be done minimum in two measuring points. Calibration points should be selected according to the required range to cover almost or fully. In every case it is necessary for the calibration: one solution which does not contain any oxygen – may be a neutral gas – for the zero standard calibration, and an other solution which has a known oxygen concentration for the full-scale standard calibration.
Zero calibration is necessary, because DO sensor gives output current when the measured medium does not contain any dissolved oxygen. This current is called residual-current. The required zero-standard is an aqueous solution of sodium-sulphite (Na
2S03
) and cobalt(II)-chloride hexahydrate (CoCl2-6H2O) prepared
according to the followings. Oxygen-free nitrogen gas can be also used as zero-standard. The zero point calibration determines the offset of the calibration line.
Required items:
1 clean pot 1 mixer 1 dl distilled water 1g sodium-sulphite (Na
2S03
)
1mg cobalt(II)-chloride hexahydrate –Analytical Reagent– (CoCl
2
-6H2O)
26 / 60  le00100a0600p_05  BKI 11 ATEX 0012 X
Before the calibration pour the salts in the distilled water with continuous mixing.
For sensitivity calibration it is necessary a full-scale standard to determine the slope of the calibration line. Water solubility of oxygen at atmospheric pressure is well known dependent on temperature and pressure, so air-saturated water is a natural choice for full-scale standard. The air-saturated water is difficult to prepare and use. Usage of water-saturated air is a more general practice as a full-scale standard, because air-saturated water and water-saturated air are the same for the DO sensor. These are same standards, because the sensor is actually measuring the chemical potential of the oxygen. This chemical potential is a force driving through oxygen molecules from the sample through the membrane into the sensor. Output current of the sensor is proportional to the amount of oxygen driving through the membrane, so this current is determined by the chemical potential of the oxygen in the sample. The amount of oxygen is the same in air-saturated water and water­saturated air, so the chemical potential of the oxygen are also the same in both phases. Consequently the output current of the sensor is also the same in both cases.
Automatic calibration on air: The sensor should be simply hold in water-saturated air. The instrument measures the output current of the DO sensor, then store the measured value if stabilized and measures the temperature of the sample. It determines the saturation vapor pressure of the water from the temperature. Then it calculates the pressure of the dry air as the difference of atmospheric pressure and the saturation vapor pressure of the water. (Value of atmospheric pressure should be entered in the menu of the instrument as a parameter, default value is 1013mbar=101,3kPa) Considering the fact, that oxygen concentration of dry air is
20.95%, it calculates the partial pressure of the oxygen. Knowing the partial pressure of the oxygen, it calculates the amount of atmospheric dissolved oxygen in
equilibrium at a current temperature using the Bunsen solubility coefficient. This calculated value is assigned to the stored output current of the sensor.
Usually it is has many difficulties to dismount the instrument or the sensor from the technologic process for the calibration. In case of this, the sensor can be calibrated to a measurement value of a portable laboratory instrument in the same technologic process. Before this type of calibration, the laboratory instrument (usually also using oxygen-permeable membrane amperometric sensor) should be calibrated in water-saturated air. The calibration procedure is described in 6.6.

4.3. MAINTENANCE OF THE PH AND ORP ELECTRODES
In this chapter you can find some recommendations regarding re-hydration, chemical cleaning and reactivation of the electrodes.
Disassembling the electrode
During this operation be careful not to expose the fragile electrode to mechanical (bending, squeezing, tensile) forces!
Hold the electrode housing with one hand and the flare nut (right-threaded) with the other one
and loosen it completely.
Then detach carefully the electrode housing from the instrument housing. Loosen the electrode carefully using a socket-wrench (size 17) and screw it off completely.
Don't use a pipe- or a double-end wrench!
Put the electrode into the storage solution or perform the following steps below.
size 17
Re-hydration
If the electrode was desiccated due to incorrect use or storage it needs to be re-hydrated. This has to be done by soaking the electrode in 3mol/l KCl storage solution at 20°C for 24 hours. The process can be shortened to 6 hours if the KCl solution is at 60°C. Note: long time desiccation or desiccation after measuring crystallizating mediums may have an irreversible effect on the electrode and thus the re-hydration may not be successful.
Chemical cleaning
The deposits and obstructions on the surface of the electrode’s membrane and on the diaphragm have to be eliminated from time to time:
1. General deposits
Rinse the electrode with warm water then dry up gently using a soft rag! Soak the electrode for 15 mins in 1.5mol/l (5%) hydrochloric acid (HCl)! Rinse the electrode again with warm water then dry up gently using a soft swab! Soak the electrode for 1 hour in 3mol/l KCl solution then perform the calibration procedure!
28 / 60  le00100a0600p_05  BKI 11 ATEX 0012 X
2. Non-organic deposits
Rinse the electrode with warm water then dry up gently using a soft rag! Soak the electrode for 15 mins in 0.1 mol/l EDTA (ethylenediaminetetraacetic acid) solution! Rinse the electrode again with warm water then dry up gently using a soft rag! Soak the electrode for 1 hour in 3mol/l KCl solution then perform the calibration procedure!
3. Protein deposits
Rinse the electrode with warm water then dry up gently using a soft rag! Soak the electrode for 15 mins in 0.5 mol/l hydrochloric acid (HCl) or in 0.1 mol/l HCl and 0.1% pepsin mixture! Rinse the electrode again with warm water then dry up gently using a soft rag! Soak the electrode for 1 hour in 3mol/l KCl solution then perform the calibration procedure!
4. Silver sulphide deposits
Rinse the electrode with warm water then dry up gently using a soft rag! Soak the electrode for 15 mins in 0.1 mol/l thiourea and 1.5 mol/l (5 %) hydrochloric acid (HCl)! Rinse the electrode again with warm water then dry up gently using a soft rag! Soak the electrode for 1 hour in 3mol/l KCl solution then perform the calibration procedure!
Note: when deposits are hard to remove try using hydrogen peroxide or sodium hypochlorite solutions.
Reactivation
Regeneration of the glass membrane: The physical or chemical damage of the glass membrane slows down the operation of the electrode. The reactivation of the membrane helps restoring the normal operation of the electrode.
Immerse ONLY the spherical part of the glass electrode into ammonium bifluoride with 10% concentration for 60 seconds then immediately
into 50-50% mixture of undiluted HCl and water for 10 seconds. This will neutralize the strong base!
Soak the electrode for 12 hours in 3 mol/l hydrochloric acid (HCl)! Rinse the electrode with water then dry up gently using a soft rag! Soak the electrode for 1 hour in 3mol/l KCl solution then perform the calibration procedure!

5. INSTALLATION
5.1. MOUNTING
When choosing the installation place please ensure proper space for later calibrations, verification or maintenance service. (see placement on page 32. ) Make sure that the transmitter is protected against overheating that can be caused by direct sunshine.Assemble the electrode with the instrument prior to the installation. It is advised to check the operation of the instrument prior to the installation in the control room. If factory settings need to be modified do it according to the Programming Description. The process connection should be selected according to the type to be installed.
ATTENTION!
When mounting or dismounting the instrument, avoid exposing the electrodes, DO sensors and temperature sensors to mechanical impacts because these can cause malfunctioning of the unit. The unit should not be loosened if the process is under pressure, in this case user should take care of depressurization first!
5.1.1. Installation of pH and ORP electrodes
Prior to mounting into the process the instrument should be put into operation-ready state. For this the user has to insert the electrode (packed separately) into the instrument as described below:
During this operation be careful not to expose the fragile electrode to mechanical (bending, squeezing, tensile) forces!
The housing of the instrument can be disassembled as described in chapter 4.3.
Remove the plug in the electrode housing from the connector
of the electrode.
Open the box and screw the electrode off the container. Insert the electrode to its place carefully, screw in with your hand and

5.1.2. Installation of DO sensor
Prior to mounting into the process the instrument should be put into operation-ready state. For this the user has to insert the DO sensor (packed separately) into the instrument as described below:
During this operation be careful not to expose the fragile DO sensor to mechanical (bending, squeezing, tensile) forces!
Remove the threaded protector- basket and the sponge-disc protector of the contacts. Unpack the DO sensor and place it into a flat surface, downward with the plastic cap. Do not wipe the out the silione grease from the back of the
membrane! Silicone grease protect the contacts against short-circuit, even if water is infliltrated.
With one hand hold the instrument upwards with its sensor, with other hand remove the (right-threaded) protector- basket of the sensor. Place the sensor into the instrument with its cap that the pins of the sensor-nest can fit into the holes in the rear side of the sensor. Remove the cap from the sensor and replace the protector- basket of the sensor.
TEMPERATURE
As it is shown in the diagram below – there may be a drop in the pressure-resistance according to the changes of the medium temperature, - which, in any case, should be considered, prior to the installation of the instrument into the technology process:
Depending on the location of the installation the instrument should be protected against any heat source or direct sunlight to avoid higher temperatures than specified!
32 / 60  le00100a0600p_05  BKI 11 ATEX 0012 X
PLACEMENT The instrument should be mounted within a max. 45° angle, compared to vertical position.
Types mounted with 4xphekl112seph / 4xorrheklseor electrode may be positioned horizontally as well!
If the unit is installed using a fitting piece the user has to assure that before and after the fitting piece there is a straight pipe with the appropriate length to minimalize sedimentation and turbulency. The influent section has to have min. 10xDN length while the effluent section has to have min. 3xDN length. It is advised to create a by-pass line so during the service of the instrument the electrode is kept wet or a calibration can be done without stopping the process.

LIQUID CONTINUITY
Near the electrode (sensor), the pipeline should always be filled with liquid:
BKI 11 ATEX 0012 X le00100a0600p_05  33 / 60
BUBBLE, FOAM Near the electrode (sensor), liquid in the pipeline should be free of bubbles or foam.
Installation of the threaded models
Screw the unit into its place and tighten by hand. Don’t use any tool! After tightening, the enclosure can be rotated to the proper position. (Safety bolt prevents rotation more than 350°).
5.1.3. Special application possibilities of the Integrated type instruments
Integrated type instruments can be installed in the same place with the medium to be measured. In this case of application, the maximal process pressure can not exceed 0.5 bar!
34 / 60  le00100a0600p_05  BKI 11 ATEX 0012 X
5.2. WIRING
The instrument operates from 12.5 … 36 V galvanic isolated and not grounded DC power supply in two wire system. (For Ex version: 12.5 … 30 V DC!) Sum of the resistance of the equipped instruments, between the transmitter and the power supply, mainly depends on the supply voltage of power supply applied, and the overall resistance value cannot exceed 1200 ohms. In case of using HART interface – to achieve proper communication between the transmitter’s interface and the power-supply – a minimal 250 ohms resistance should be maintained within the network.
5.2.1. Wiring of Compact instruments
The instrument should be wired with shielded cable led through the cable gland. The wiring of cables can be done after removing the cover of the instrument and the SAP display unit.
Make sure that the power supply is turned off at the source. After removal of the cover of the housing and taking the display module (if any) out,
the wiring cables can be connected. (Recommended cable: shielded, two-wire, with
0.5 ... 1.5 mm2 cross section. Connect shielding to grounding by the inner or outer grounding screw first.
Switch on the unit. After switching of the unit, necessary programming can be done. After the wiring, adjustment and programming, check proper sealing and close the
cover carefully.
IMPORTANT: - The housing of the transmitter should be grounded to the EPH network. Resistance of the EPH network should be R 2 ohm measured from the neutral. Shielding of the cable should be grounded at the control room side to the EP network. To avoid disturbing noises, keep away of closeness to high-voltage cables. Especially critical can be the inductive couplings of harmonics (which are present at frequency converter control) because even cable shielding does not supply effective protection against these cases.

5.2.2. Wiring of Integrated instruments
The insrument can be connected directly to the suitable power suply unit. When extending the cable, a junction box is needed to use for this purpouse. Shielding should be connected with the shield of the extending cable and should be grounded at the signal processing device.
Make sure that the power supply is turned off at the source. (Recommended cable: shielded cable with 6 x 0.5 mm
2
or greater cross section).
Turn on the power supply. After switching of the unit, necessary programming can be
done.

Especially critical can be the inductive couplings of harmonics (which are present at frequency converter control) because even cable shielding does not supply effective protection against these cases.
5.3. LOOP CURRENT CHECKING WITH HAND INSTRUMENT
After removing the cover and lifting the Display Module, the actual loop current can be measured with an accuracy of ~ 5% by connecting a voltmeter (in the range of 200 mV) to the points indicated on the drawing above.
5.4. CONDITIONS OF EX APPLICATION
Intrinsically safe units with Ex ia IIB marking can only be used in certified intrinsically safe loops with the previously given technical data. (see values in special
data for Ex approved models under Point 3).
The size of the macrolon window of intrinsical safe equipment with metallic enclosure exceeds the limit, thus the devices must be protected against electrostatic
charges.
Equipment with plastic housing are susceptible to electrostatic charges, thus the deivces must be protected against electrostatic charges. The aluminium content of equipment with metallic enclosure exceeds the limit, the devices must be protected against impact and friction effects. Devices should be grounded by connecting their grounding screws to the equipotential system.

6. PROGRAMMING
The AnaCONT instruments can be programmed with the SAP-300 display unit. Without SAP-300 the following LEDs can be seen:
RELAY Indicates the energised state of the relay (C2 closed, C1 open) VALID Indicates the measuring capability of the unit. If lit, the input signal is stabilised.
If blinking,the input signal is changing.
COM Indicates digital (HART) communication. During Remote programming LEDs are
continuously illuminated.
When SAP-300 display is present, LEDs are not visible; functions are taken over by the display. In default state SAP display shows the primary measured value (which the output current is calculated from). Programming is supported by a text-based menu. Navigation is done by using the

The instrument can operate without the SAP-300 module as well. Programming can be done only by using SAP-300 display module locally or by HART (REMOTE PROGRAMMING) communication system remotely.
6.1. THE SAP-300 DISPLAY UNIT
The SAP-300 is a 64x128 dot-matrix LCD display which can be plugged into the transmitter. (Universal – usable in other NIVELCO devices as well – provided that the system software supports SAP-300.)
Warning!
The SAP-300 module is based on LCD technology, so please make sure it is not exposed to permanent heat or direct sunlight, in order to avoid damage of the display unit. If the instrument cannot be protected against direct sunlight or high temperature that is beyond the standard operating temperature range of the SAP-300, please do not leave the SAP display in the instrument.

6.2. MEASURING WITH THE SAP-300 DISPLAY UNIT
Elements of the display:
1. Primary value (PV), in a dimension depended on the type of the instrument
2. SENSOR VOLTAGE – informative data in case of pH measurement
3. Trend direction arrows. The empty triangle shows when the measured value is small, the filled triangle shows
large-scale change. If none of the arrows are shown the measured value is constant.
4. Measured value in relation to measurement range (Sensor range) in a bargraph.
5. Temperature is shown for temperature compensation (measured by internal sensor).
After the dimension, the temperature compensation mode is indicated by inverse inscription: Any possible errors during measurement are shown in the lower part of the display.
Manual mode (see 6.4.1.3)
Temperature simulation active (see 6.4.5.8)
Temperature sensor error. In this case the instrument will compensate to 25 ºC.
6. Indication of primary value simulation. In this case the display and output will show the values of the simulation
and not the measured value.
7. Measured value normalized to 25˚C, 760Hgmm and Salinity=0 – informative data (only for DO transmitters)
8. Oxygen saturation (only for DO transmitters)
During active simulation the critical measurement errors will be displayed to give information to the user.

6.3. PROGRAMMING WITH THE SAP-300 DISPLAY MODULE
When entering the menu the instrument makes a copy of the actual parameters, all changes are done to this duplicated parameter set. During programming the instrument keeps measuring and transmitting with the current (and intact) parameter set. After exiting the menu the instrument replaces the original parameters with the new parameter set and will measure according the new parameters. This means that the change of the parameters does not become immediately effective when pressing the E button!
Entering the menu can be done by pressing the E button while exiting the menu can be done by pressing the button. If the instrument is left in programming mode after 30 mins it will automatically return to measuring mode. If the SAP display is removed during programming the instrument immediately returns to measuring mode.
As programming with SAP-300 (manual programming) and HART (remote mode) programming is not possible at the same time use only one programming method at a time. Measured values can be read out through HART at any time
6.3.1. Components of the programming interface
The parameters of the instrument are grouped according to their functions. The programming interface consists of lists, dialog windows, edit windows and report windows.
Lists
Navigation between the lines of a list can be done by pressing / buttons. Pressing the E button activates a list item. Selected list item is marked with inverse colour. Exit from a list by pressing the
button.
Menu list
Menu list is a specialized list. Its characteristic is that upon selecting a list item we directly get into another list, and these lists are opening from each other in different levels.
The menu header (1) helps to navigate.
Entering the menu can be done by pressing the E button. Navigation between the menu items can be done by pressing the
/ buttons. Enter to the selected menu by pressing the E button. The selected list item
is marked with inverse colour.
Exit from a submenu with
button. Pressing the button in the main menu will exit programming mode and
the instrument will return to measuring mode.

Dialog window
The system sends messages or warnings using dialog windows. These usually can be acknowledged by pressing the
button or the user can choose between two options (usually YES or NO) by pressing /
buttons. In some cases to correct an error one of the parameters has to be changed
WARNING LOAD DEFAULT TO PARAMETER TABLE! ARE YOU SURE?
[YES] [NO]
Edit window
An edit window is used for modifying a numeric parameter value. The selected character can be changed using the
/ buttons. The cursor can be moved to left, using the button. The direction of the cursor movement through the digits is right to left. Changed value can be validated by pressing the E button. The software checks if the entered value is appropriate, exiting the edit window is only possible after entering a correct value. If the entered value is uninterpretable the software sends an error message in the bottom line (1) of the display. The display gives the same error message, independently of the measured value and the measurement principle.
PV: primary Value
Edit window – button combinations
In the edit window the following button combinations are available:
1. Recalling the parameters to the state before editing ( + , pressed for 3 secs);
2. Recalling default parameters (
+ , pressed for 3 secs);
3. Inserting (currently) measured value to the edit window (
+ , pressed for 3 secs)

This function is for periodic calibration of the pH sensor. Entering the SERVICE / SENSOR CALIBRATION menu the instrument will display a warning message that the user is about to change critical parameters of the
measurement system. The user can enter the menu by pressing the
(OK) button or exit to the previous menu by pressing the (NO) button. In case of calibration, after sensor replacement, please handle first calibration with high priority. The system will inquire this in the next dialog box. In the event of initial calibration, press the OK button. In this case, all parameters and counters related to the sensor will be reset to default. We should press
NO button, in case it is not the first calibration.
In the SENSOR INFO page the slope and offset voltage of the sensor can be checked (see chapter 6.2). The calibration can be performed within ±0.8 pH sensor error. When this error is greater then ±0.8 pH the unit shows a warning message that the sensor should be
replaced.
6.5.1. Editing one item of the calibration table
(SERVICE | SENSOR CALIBRATION | VIEW/EDIT TABLE) Calibration of the pH sensor is done using this table with min. 2 or max. 8 elements. By default the table contains
2 elements (0 and 14pH). The instrument is ready to measure with these two elements in the table. Any change in the calibration table applies instantly! The two minimal elements of the table cannot be erased only edited.
The selected element of the list (table) can be edited by pressing the
E
button. Then we get a special box editor.
One line of the list consists of two values. The left one (BUFFER VALUE) shows the nominal value of the used pH buffer solution. The right one (SENSOR VALUE) indicates the uncalibrated but temperature compensated value measured with this buffer solution.

Adding, modifying a calibration point
The following special screen helps the user to set a calibration point. The user can see the uncalibrated measured values and also the pair values of the selected table line.
1. Value, measurable without sensor calibration
2. Trend display for monitoring installation. The upper part of the bargraph symbolizes the increasing trend, the bottom part of
the bargraph symbolizes the decreasing trend. The filling rate is in accordance with the measure of change. If the bargraph is empty, the measured value is constant.
3. Measured value with calibration.
4. The BUFFER VALUE is editable using the
, and buttons. The user has to
enter the nominal pH value of the measured buffer solution.
5. The measured value can be copied to the stored SENSOR VALUE by pressing the
+ buttons simultaneously. Then the software starts an algorithm to check if the measured value is stable or not. When the value is stored in the SENSOR VALUE field, a READY message appears on the bottom of the display.
The measured value can be copied to the stored SENSOR VALUE by pressing the + buttons simultaneously. If the two values of the data pair differ in more than ±0.8 pH from each other the software shows an error message at the bottom line of the screen.
By pressing the
E
button the instrument checks the edited calibration data pair and if it is OK the software returns to the calibration table. If not a dialogue window
will appear and inform the user.
Exit from the calibration table by pressing the
button.
Damping check:
When pressing the
+ buttons the software checks if the calibration value to be stored is constant. After the buttons are pressed the measured pH value must be stabilized in 30 seconds otherwise the value will not be stored and a FAILED! message will appear on the screen. Change in the measured value (1) can be followed on the trend bargraph (2). If the cause of a fluctuation or error is eliminated, storing of the calibration points can be repeated by pressing the
+
buttons again.

This function is for periodic calibration of the DO sensor. The sensor is aging during the usage of the instrument. When the life-time of the sensor is over the sensor should be replaced. In case of sensor replacement the
sensor should be calibrated compensating the aging. Calibration of the sensor has to be done in two points: (ZERO – zero point and SPAN – saturated value) ZERO calibration can be performed with 5% sodium sulphite referential liquid, SPAN (saturated value) calibration can be performed with saturated zero salinity
referential liquid or air. Value of atmospheric pressure should be set before calibration process (see 6.4.1.8.) Entering the SERVICE / SENSOR CALIBRATION menu the instrument will display a warning message that the user is about to change critical parameters of the
measurement system. The user can enter the menu by pressing the (OK) button or exit to the previous menu by pressing the (NO) button. In case of calibration, after sensor replacement, please handle first calibration with high priority. The system will inquire this in the next dialog box. In the event of initial calibration, press the
OK button. In this case, all parameters and counters related to the sensor will be reset to default.
We should press
NO button, in case it is not the first calibration.
6.6.1. Calibration of saturated value (100%)
(SERVICE / SENSOR CALIBRATION / CAL. IN AIR (SPAN)) Rinse the DO sensor with distilled water then dry up gently using a soft rag. Immerse the sensor into
saturated, zero salinity referential liquid or hold the sensor into air. Please wait until the measured value (2) get stabilized. Change in the measured value (2) can be
followed on the trend bargraph (1). Achieving proper calibration atmospheric pressure (3) and relative humidity (4) should be entered. In accordance to these values and the measured temperature the instrument calculates the DO concentration, which can be edited in the last line (5).
Damping check:
When pressing the E button at the last line, a warning message appears asking do we really want to store the calibration data. By pressing the
[yes – OK] button, the instrument checks the stability of the measured value and if it remains unchanged during a given time period, the instrument stores the calibration. Changes of the measured value can be checked on the display (2) and the trend bargraph (1) also indicates changes of the measured value. When the measured value got stabilized, READY! message will appear on the bottom of the screen. If damping check procedure is unsuccessful, FAILED! message will appear on the bottom of the screen. When the error caused by changes or fluctuations became resolved, then calibration-point storing procedure can be repeated.

6.6.2. Calibration of Zero point (0%)
(SERVICE / SENSOR CALIBRATION / CAL. IN ZERO SOL.) Rinse the DO sensor with distilled water then dry up gently using a soft rag. Immerse the sensor into
5% sodium sulphite referential liquid. Please wait until the measured value (2) get stabilized. Change in the measured value (2) can be
followed on the trend bargraph (1).
When pressing the E button at the last line, a warning message appears asking do we really want to store the calibration data. By pressing the [yes – OK] button we enter the damping check procedure described in the previous point.
6.6.3. Calibration with referential DO instrument
(SERVICE / SENSOR CALIBRATION / CAL. IN SPAN SOL.) With this function the instrument can be calibrated to a referential (already calibrated) instrument.
In this case basic settings (atmospheric pressure, temperature) should be the same. Rinse the DO sensor with distilled water then dry up gently using a soft rag. Immerse the sensor into
saturated referential liquid with zero salinity or hold the sensor into air. Please wait until the measured value (2) get stabilized. Change in the measured value (2) can
be followed on the trend bargraph (1). Read the measurement value of the referential instrument and enter this value to the edit field (3).
When pressing the E button at the last line, a warning meassage appears asking do we really want to store the calibration data. By pressing the [yes – OK] button we enter the damping check procedure described in 6.6.1 point.
6.6.4. Reset the calibration table to default
(SERVICE | SENSOR CALIBRATION | DELETE ITEM)
This function resets the sensor calibration data to default. It is ineffective to other operating parameters.
6.6.5. Reset Timer
This function resets the inner timer of the DO electrode life-time monitoring routine.
