10.1 General

This chapter explains in detail all submenus and setting options for inputs/ outputs and display functions in the "Configuration" menu.
Complete configuration of the device is described in the operating manual.
Operating manual B 202581.0

10.2 Important information

WARNING!
After every configuration change, the device restarts functions affected by the changes. Analog and digital outputs can assume undesired states during start­up.
Therefore, configuration changes must never be made while equipment is op­erating!
CAUTION!
Besides incorrect installation, incorrectly set values on the device can impair performance of the connected process or cause damage. Therefore, always provide safety devices independent of the device and allow only qualified per­sonnel to make settings.

10 Configuration

CAUTION!
When changing configuration data that are relevant for the data monitoring and recording function, data recording is terminated and a new recording session begun.
NOTE!
Changes to the configuration settings described in this chapter can be made directly on the device or via the JUMO PC setup program.
NOTE!
Settings in the "Configuration" menu can be changed only if a user with corre­sponding user rights is logged in.
Chapter 8.1.1 "Passwords and user rights", page 77
NOTE!
Changes to the configuration go into effect only after you leave the configura­tion menu ("Exit" menu item or "Close window" button).

Chapter 10.12 "Calibration timer", page 46
NOTE!
The following points must be observed for correct operation of glass electrode monitoring via impedance measurement (see preceding table):
Impedance measurements are possible only with glass-based sensors.
Sensors must be connected directly to an analysis input for pH/Redox/NH on the device.
Impedance converters must not be installed in the measuring circuit.
The maximum admissible cable length between sensor and device is 10 m.
Fluid resistances have a direct impact on the measurement result. It is therefore advisable to activate the impedance measurement in liquids at a minimum conductivity of approx. 100 µS/cm.

10.10 Digital sensors

NOTE!
For operation of digital sensors, you need the extra code "JUMO digiLine pro­tocol activated“ (see Chapter 4.2 "Order Details", page 17)
NOTE!
Only one serial interface of the device can be configured for operation of digital sensors. If your device has 2 serial interfaces (base unit and possibly an op­tional board), select 1 interface for connection of digital sensors and configure it appropriately.
NOTE!
Correct functioning of digital sensors depends on correctly setting the interface to which the digital sensors are connected and are to be operated. Make sure the selected serial interface is configured correctly.

10.12 Calibration timer

Every input for analysis measurands has its own calibration timer. Inputs for temperature sensors do not have a calibration timer, since they do not need to be calibrated. Calibration timers signal when sensor calibration is due via a cal­ibration alarm. Once a particular input has been calibrated successfully, its cal­ibration timer is reset. The signal for a due calibration can be generated, for instance, by binary outputs with external external indicator lights or the alarm/ event list. The structure of the calibration timer configuration of sensors with JUMO digiLine electronics differs from that of all other analysis sensors. In this case, there is only the "Calibration interval" parameter. Observe the following configuration table.

11.1 Important information

WARNING!
During the calibration, the relays and analog output signals assume the states configured for the calibration! The response of the output signals is set for each output in its "Response at calibration" configuration point.
Chapter 10.7 "Analog outputs of base unit and optional boards", page 28

11.2 General information

The actual electrical characteristics of analysis sensors always deviate some­what from the nominal specifications. The reasons for this include:
Like every measuring instrument, analysis sensors always have a certain uncertainty of measurement that results from manufacturing tolerances.
During use, analysis sensors are exposed to chemical processes. Deposits and wear phenomena caused by these processes result in changes of the electrical characteristics of sensors.
To optimize the accuracy of measurements, analysis sensors must be calibrat­ed. Calibrations are required:
during installation or when changing a sensor
regularly at time intervals that must be specified by the user
if implausible measured values are displayed
if process conditions change, e. g. as the result of equipment modification

11 Calibration in general

Calibration timers can be configured to provide a regular reminder of when cal­ibrations are due.
Chapter 10.12 "Calibration timer", page 46
Each successfully completed calibration is recorded in the calibration logbook.
Chapter 11.3 "Calibration logbook", page 51

11.2.1 General procedure for calibration

True calibration (calibrating with routines)
After opening one of the calibration routines in the device, the user is guided through a process with measurements and entries. In the course of this process, the calibration values are determined and saved automatically. Suitable calibration routines are available for every type of analysis sensor. The individual calibration routines for the various sensor types are described in sep­arate chapters.
Chapter 12 "Calibrating a pH measuring chain", page 55 to Chapter 16 "Cali-
brating Ci conductivity sensors", page 79
Execution of calibration routines requires that the following prerequisites be met:
49
11 Calibration in general
You must be logged in as a user with the right to perform calibrations. Fac­tory-preset users have all of these rights.
"Passwords and user rights", page 77
You must ensure that the calibration default settings for the individual analy­sis inputs and, possibly, the universal inputs are set correctly. The explana­tions of the calibration default settings can be found in the chapters on calibration of the various analysis sensors.
In the case of Ci analysis inputs, it should be noted that the optional boards must undergo a basic calibration during the initial commissioning. If this has not yet been performed, it is necessary to do so prior to any other calibration.
Chapter 9.3 "Ci base calibration", page 121
Manual entry of calibration values
NOTE! Incorrectly entered calibration values result in incorrect measured values. Correct measurements are essential for control systems and limit monitoring.
If calibration values are known, they can also be entered manually. This may be the case with temperature-compensated conductivity measurements, for in­stance, when the temperature coefficient of a liquid is known. Another important application case is the manual entry of relative cell constants of conductivity sensors. If an ASTM test certificate showing precisely-measured cell constants is available, in addition to entering the nominal cell constants in the configuration of the conductivity sensor concerned (cf. Chapter 10.6.6 "CR/Ci analysis inputs (conductive/inductive conductivity)", page 23), the relative cell constants of all measuring ranges in the calibration values must be manually entered. The rela­tive cell constants must be calculated from nominal cell constants (nameplate for the sensor) and measured cell constants (ASTM test certificate): (measured cell constant × 100 %) ÷ nominal cell constant = relative cell con­stant.
Calculation example: nominal cell constant = 0.1 cm-1 measured cell constant = 0.1014 cm rel. cell constant = (0.1014 cm
Known calibration values are entered manually under:

11.3 Calibration logbook

A separate logbook is maintained for each analysis and universal input. The last 10 successful calibrations of the input concerned are saved in the cal-
ibration logbook. Canceled or failed calibrations (calibrations outside the per­missible limits) are not saved in the logbook, but rather noted in the event list. Manual changes of calibration values on the device are also documented. The following data are retained in the logbook:
Heading with description of the measurement input and calibration method
Date and time
Measurand
Calibration assessment (assessment of the calibration values determined during the true calibration)
Calibration values determined or entered
Reference values used
Calibration mode (true calibration/manual entry of calibration values)
Since this information does not yet fit in a screen line, the logbook entries are listed in abbreviated form with the date and calibration results for the time being. More exact information can be accessed for every entry via the detail view.

12 Calibrating a pH measuring chain

12.1 Important information

WARNING!
During the calibration, the relays and the analog output signals assume the states configured under the respective "Response at calibration' configuration points for the analog and digital outputs!

12.2 General information

The calibration of pH electrodes is based on measurements in buffer solutions with a defined pH-value. The pH values of the buffer solutions used are specified either via entry of fixed values into the calibration default settings, entered during the calibration or recognized automatically by "automatic buffer recognition" during the calibration process. For "automatic buffer recognition", a buffer set ta­ble must be selected in the calibration default settings. In this case, the buffer solutions used must be listed in the provided buffer set table. Since pH value measurement of liquids is temperature-dependent, the temperature of the buffer solution must be sensed in order to compensate for its effect on the result of the measurement. This requires either manual entry or measurement with the aid of a temperature sensor.

12.2.1 Calibration methods for pH sensors

Zero-point calibration
This calibration method is used to determine the pH zero point on the measure­ment characteristic curve. The slope is retained.
A buffer solution with a defined pH value is needed as a reference.
Two-point Calibration
By measuring 2 different buffer solutions with defined pH values, the pH zero point and pH slope of the measuring chain are established.
The pH values of the buffer solutions must be at least 2 pH apart. This calibration method is recommended for most applications.
Three-point calibration
With a three-point calibration, the pH zero point as well as the pH slope in the acidic region and the pH slope in the alkaline region are established. The three­point calibration can be performed only for pH sensors on analysis inputs. It is not available for JUMO digiLine pH sensors.
This method requires 3 buffer solutions with defined pH-values as references. One of these must be acidic, one neutral and one alkaline. The pH values of the buffer solution must be at least 2 pH apart from one another. This calibration method is recommended for applications with more demanding accuracy re­quirements when performing measurements in both the alkaline and acidic re­gions.

Buffer set tables contain pH values for selected buffer solutions as a function of temperature. These tables can be pre­pared/edited using commercially avail­able standard solutions (DIN 19266, NIST; otherwise, technical buffer solu­tions etc.) or on the basis of customer­specific information. With their aid, buffer solutions can be recognized auto­matically when calibrating. The pH val­ue data for the buffer solutions used must be contained in the buffer set table selected. When a buffer set is selected, this acti­vates automatic buffer recognition and the entry fields for the settings "pH buf­fer 1 to 3" are hidden. You need the JUMO PC setup program to edit buffer set tables.

13.2 General information

The calibration of Redox sensors is based on measurements in test solutions with a defined Redox potential.

13.2.1 Calibration methods for Redox sensors

Zero-point calibration
This calibration method is used to determine the redox zero point. A test solution with a defined redox potential is needed as a reference. "mV" must be set as the redox unit in the configuration of the redox measure-
ment input (analysis input or input for digital sensors).
Chapter 10.6.4 "pH/Redox/NH3 analysis inputs", page 21
Two-point Calibration
This calibration is used to establish an application-specific measurement char­acteristic curve where redox potentials are represented as a percentage of con­centration values. The redox potentials of 2 solutions are measured. Concentration values in percent are then assigned to the measured values by the user.
Two process-typical sample solutions are needed as calibration solutions as a reference. "Percent" must be set as the redox unit in the configuration of the redox mea­surement input (analysis input or input for digital sensors).
Chapter 10.6.4 "pH/Redox/NH3 analysis inputs", page 21
Example: In a detoxification plant, the toxicity of a liquid is to be measured on the basis of the Redox potential. The calibration requires 2 solutions:
the concentration of the highly toxic solution is given as 80 % by the user, for
the concentration of the detoxified solution is given as 10% by the user, for
Using the redox potential, the toxicity can now be measured and displayed in percent.

15 Calibrating CR conductivity sensors

15.1 Important information

WARNING!
During the calibration, the relays and analog output signals assume the states configured for the calibration! The response of the output signals is set for each output in its "Response at calibration" configuration point.
Chapter 10.7 "Analog outputs of base unit and optional boards", page 28

15.2 General information

The calibration of CR sensors is based on measurements in test solutions with a defined electrolytic conductivity. Since the electrolytic conductivity of liquids is temperature dependent, the temperature of the test solution must be sensed. This requires either manual entry or measurement with the aid of a temperature sensor.

15.2.1 Calibration methods for CR conductivity sensors (conductive)

Rel. cell constant
The deviation from the nominal cell constant of a CR sensor is described by the relative cell constant. The rel. cell constant is determined by making a measure­ment in a test solution with a defined conductivity.
Temperature coefficient
The temperature coefficient is a measure of the temperature dependence of the electrolytic conductivity of a liquid. It is used to compensate for the effect of tem­perature when measuring the electrolytic conductivity. When performing a tem­perature-compensated conductivity measurement, the conductivity value measured is always indicated with reference to the fixed reference temperature. With the aid of the temperature coefficient, the value of the electrolytic conduc­tivity displayed at the reference temperature is calculated from the current mea­sured values of conductivity and temperature of the liquid. Reference temp. is set in the configuration of the individual CR analysis input.
Chapter 10.6.6 "CR/Ci analysis inputs (conductive/inductive conductivity)",
page 23 The temperature coefficient is determined from 2 measurements in a test solu­tion at different temperatures (reference and operation temp.).
NOTE!
If the temperature coefficient of a sample solution is known, it can be entered directly.

If the conductivity of a liquid whose temperature coefficient changes with tem­perature has to be measured, this method can determine 5 temperature coeffi­cients for 5 temperature intervals. In this way, it is possible to determine a good approximation of the temperature coefficient curve. While the operator brings the sample solution to the temperature values requested by the device, the de­vice determines the temperature coefficient for each interval. This requires in­stallation of a temperature sensor that the device can use to sense the temperature of the sample solution.

18 Calibrating O-DO sensors

18.1 Important information

WARNING!
During the calibration, the relays and analog output signals assume the states configured for the calibration! The response of the output signals is set for each output in its "Response at calibration" configuration point.
Chapter 10.7 "Analog outputs of base unit and optional boards", page 28

18.2 General information

Depending on the calibration method, O-DO sensors are calibrated on the basis of measurements in water and water sulfite solutions (sulfite concentration < 2 %).
NOTE!
As the manufacturing of air-saturated water requires a high level of effort and is difficult to reproduce, the easier process of calibration in water vapor-saturated air is recommended for the operational calibration.
Positioning the sensor in the water vapor-saturated air
To achieve successful calibration, the following points must be taken into ac­count:
The sensor must be kept dry during the calibration process. Drops of water adhering to the sensor membrane could distort the measurement result.
The air pressure and temperature must remain constant during the calibra­tion.
99
18 Calibrating O-DO sensors
Sample screen: O-DO calibration default settings

18.2.1 Calibration methods for O-DO sensors

End value calibration
With end value calibration, the slope of the sensor is calibrated beyond the de­fined state of 100 % oxygen saturation. This state can in principle be achieved in two ways:
By positioning the sensor in water vapor-saturated air (for example, directly over a water surface).
By positioning the sensor in air-saturated water (air is directed through water until the water is saturated with it).
Two-point Calibration
With two-point calibration, the zero point and slope of the sensor are calibrated. This calibration method offers the greatest possible level of accuracy and is par­ticularly recommended for measurements of small oxygen concentrations.

18.2.2 Calibration default settings for O-DO sensors

Before you can perform a calibration, you must first enter the necessary calibra­tion default settings. The possible settings for the O-DO calibration are de­scribed in the following.
Open the calibration default settings: Device Menu > Calibration > Digital Sensor 1 to 6 > Calibration Default Settings
NOTE!
The "Calibration default settings" menu appears in the Device menu only if a user with corresponding user rights is logged in. The "Calibration default set­tings" menu for a digital sensor is visible for the digital sensor concerned only when it is linked.
