1.2 Sensors

1.2.1 IDS sensors

IDS sensors
support the automatic sensor recognition
show only the settings relevant to the specific sensor in the setting menu
process signals in the sensor digitally so that precise and interference-free
measurements are enabled even with long cables
facilitate to assign a sensor to a measured parameter with differently colored
couplings
have quick-lock couplings with which to fix the sensors to the meter.
Sensor data from
IDS sensors
IDS sensors transmit the following sensor data to the meter:
SENSOR ID
– Sensor name
– Sensor series number
Calibration data
Measurement settings
The calibration data are updated in the IDS sensor after each calibration proce­dure. A message is displayed while the data are being updated in the sensor.
In the measured value display, you can display the sensor name and series number of the selected sensor with the [Info] softkey. You can then display further sensor data stored in the sensor with the [More] softkey (see section 4.1.6 S
ENSOR INFO, page 17).

MultiLab 4010-3 Overview

1.2.2 IDS adapter for analog sensors

With the aid of an IDS adapter, you can also operate analog sensors on the MultiLab 4010-3. The combination of the IDS adapter and analog sensor behaves like an IDS sensor.
The MultiLab 4010-3 has a recess where the IDS adapter (ADA 94/IDS DIN or ADA 94/IDS BNC), which is available as an accessory, can be permanently mounted.
The IDS adapter replaces a digital input (channel 2) with a connector for an analog pH/ U/ISE sensor (DIN or BNC plug) and a temperature sensor.

1.2.3 Automatic sensor recognition

The automatic sensor recognition for IDS sensors allows
to operate an IDS sensor with different meters without recalibrating
to operate different IDS sensors at one meter without recalibration
to assign measurement data to an IDS sensor
– Measurement datasets are always stored and output with the sensor
name and sensor series number.
to assign calibration data to an IDS sensor
– Calibration data and calibration history are always stored and output with
the sensor name and sensor series number.
to activate the correct cell constant for conductivity sensors automatically
to hide menus automatically that do not concern this sensor
To be able to use the automatic sensor recognition, a meter that supports the automatic sensor recognition (e.g. MultiLab 4010-3) and a digital IDS sensor are required. In digital IDS sensors, sensor data are stored that clearly identify the sensor. The sensor data are automatically taken over by the meter.

5.1 Measuring

5.1.1 Measuring the pH value

The sensor connection and the USB-B (device) interface are gal­vanically isolated. This facilitates interference-free measurements also in the following cases:
Measurement in grounded test samples
Measurement with several sensors connected to one
MultiLab 4010-3 in one test sample
1. Connect the IDS pH sensor to the meter.
The pH measuring window is displayed.
2. If necessary, select the measured parameter with <M>.
Stability control
(AutoRead)
& HOLD function
3. Adjust the temperature of the solutions and measure the current tem-
perature if the measurement is made without a temperature sensor.
4. If necessary, calibrate or check the IDS pH sensor.
5. Immerse the IDS pH sensor in the test sample.
The stability control function (AutoRead) continually checks the stability of the measurement signal. The stability has a considerable impact on the reproduc­ibility of measured values.
The measured parameter flashes on the display
as soon as the measured value is outside the stability range
when the automatic Stability control is switched off.
You can start the Stability control manually at any time, irrespective of the set- ting for automatic Stability control (see section 10.6.3 A
CONTROL, page 97) in the System menu.
UTOMATIC STABILITY
1. Freeze the measured value with <AR>.
The [HOLD] status indicator is displayed. The HOLD function is active.
ba76143e03 08/2013 27
Page 28

You can terminate the Stability control function and the HOLD func­tion with <AR> or <M> at any time.
2. Using <ENTER>, activate the Stability control function manually.
The [AR] status indicator appears while the measured value is assessed as not stable. A progress bar is displayed and the display of the mea­sured parameter flashes. As soon as a measured value meets the stability criteria, it is frozen. The [HOLD][AR] status indicator is displayed, the progress bar disappears and the display of the measured parameter stops flashing. The current measurement data is output to the interface. Measurement data meeting the stability control criterion is marked by AR.
You can prematurely terminate the Stability control function manu­ally with <ENTER> at any time. When the Stability control function is prematurely terminated, the current measurement data are out­put to the interface (PC, USB memory device or USB printer) with­out AutoRead info.
Criteria for a stable
measured value
3. Using <ENTER>, start a further measurement with stability control.
or Release the frozen measured value again with <AR> or <M>. The [AR] status display disappears. The display switches back to the pre­vious indication.
The Stability control function checks whether the measured values are stable within the monitored time interval.
Measured
Time interval Stability in the time interval
parameter
pH value 15 seconds
Temperature 15 seconds
Δ : Better than 0.01 pH
Δ : Better than 0.5 °C
The minimum duration until a measured value is assessed as stable is the monitored time interval. The actual duration is mostly longer.

5.1.2 Measuring the temperature

For reproducible pH measurements, it is essential to measure the temperature of the test sample.
IDS sensors measure the temperature with a temperature sensor integrated in the IDS sensor.
When operating a sensor without integrated temperature sensor, e.g. via an IDS pH adapter, you have to measure and enter the temperature of the test sample first.

5.2 pH calibration

5.2.1 Why calibrate?

pH electrodes age. This changes the zero point (asymmetry) and slope of the pH electrode. As a result, an inexact measured value is displayed. Calibration determines and stores the current values of the zero point and slope of the electrode. Thus, you should calibrate at regular intervals.

5.2.2 When do you have to calibrate?

Routinely within the framework of the company quality assurance
When the calibration interval has expired

5.2.3 Carrying out automatic calibration (AutoCal)

Make sure that in the sensor menu, Buffer menu, the buffer set is correctly selected (see section 10.1.1 S
ETTINGS FOR PH MEASUREMENTS, page 84).
Use one to five buffer solutions of the selected buffer set in any order.
Below, calibration with YSI buffers (YSI) is described. When other buffer sets are used, other nominal buffer values are displayed. Apart from that, the proce­dure is identical.
If single-point calibration was set in the menu, the calibration proce­dure is automatically finished with the measurement of buffer solu­tion 1 and the calibration record is displayed.
1. Connect the pH sensor to the meter.
The pH measuring window is displayed.
2. Keep the buffer solutions ready.
When measuring without temperature sensor: Temper the buffer solutions or measure the current temperature.
3. Start the calibration with <CAL>.

5.2.8 QSC function (sensor quality control)

General information
on the QSC function
The QSC function (Quality Sensor Control) is a new sensor evaluation for digital IDS sensors. It evaluates the condition of an IDS pH sensor individually and with a very fine grading.
The QSC scale shows the current sensor evaluation with an indicator on the display.
1 QSC scale
The double arrow on the QSC scale indicates the current sensor eval­uation
In the USB output the sensor evaluation is given as a percentage (1-100).
The finely graded sensor evaluation of the QSC function promptly calls your attention to changes of the sensor. Thus you can do what is necessary to restore the optimum measuring quality (e.g. clean, calibrate or replace the sensor).
Sensor evaluation
with / without QSC function
With QSC function Without QSC function (sensor sym-
bol)
Very fine grading of the sensor eval­uation (100 grades)
The reference value is individually determined for each sensor during
Rough grading of the sensor evalua­tion (4 grades)
A theoretical reference value is used for all sensors
the QSC initial calibration. Low tolerances for zero point and
slope when using QSC buffer solu­tions
Additional QSC calibration required
Greater tolerances for zero point and slope when using commercial buffer sets
No additional calibration required
(with special QSC buffer set)
QSC calibration The QSC function is enabled by once carrying out an additional three-point cali-
bration with special QSC buffer solutions. It covers the measuring range of the sensor (pH 2 to pH 11). The QSC initial calibration determines the actual condi­tion of the sensor and stores it as a reference in the sensor. To meet the high requirements of a QSC initial calibration, the QSC initial cali­bration should optimally be carried out with the initial commissioning of the sensor.

Carry out the normal calibrations for your special measuring range with your usual standard solutions as previously done.
As soon as the QSC function was enabled for an IDS sensor, it is not possible to return to the sensor evaluation with the sensor symbol for this sensor.
Carrying out a QSC
initial calibration
1. Open the menu for measurement settings with <ENTER>.
2. In the QSC menu, select First calibration with <><>.
The calibration display appears. AutoCal QSC-Kit is displayed as the buffer. Exclusively use the QSC-Kit for the QSC calibration. If you use other buffers, you will have no valid QSC calibration.
3. Calibration with the buffers of the QSC-Kit is done like a normal three­point calibration. Follow the user guide.
Carry out the QSC initial calibration very carefully. It determines the reference value for the sensor. This reference value cannot be overwritten or reset. As soon as the QSC function was enabled, it is not possible to return to the sensor evaluation with the sensor symbol.
4. As soon as the three-point calibration has been successfully carried out you can decide whether to accept or discard the calibration as the QSC initial calibration.
The QSC initial calibration is completed. The sensor is calibrated. If you want to calibrate with special buffers for your measurements, you can subsequently carry out a normal calibration with your buffers. The reference values deter­mined with the QSC calibration are also used for the evaluation of normal cali­brations. In the measured value display, the QSC scale of the QSC function is always displayed. A double arrow on the QSC scale indicates the current sen-

7.2 Calibration

7.2.1 Why calibrate?

Ion-selective electrodes age and are temperature-dependent. This changes the slope. As a result, an inexact measured value is displayed. Calibration determines the calibration line of the electrode and stores this value in the meter. Thus, you should calibrate before each measurement and at regular intervals.

7.2.2 When to calibrate?

Before any measurement if possible
After connecting another ISE electrode

7.2.3 Calibration (ISE Cal)

ISE Cal is the conventional two-point to seven-point calibration procedure that uses 2 to 7 freely selectable standard solutions. The concentration expected for the measurement determines the concentration of the calibration standards.
1. Connect the ISE combination electrode to the meter.

You can switch between the following displays with <M>:
D.O. concentration [mg/l]
measured parameter
D.O. saturation [%]
Salinity correction When measuring the D.O. concentration of solutions with a salt content of more
than 1 psu, a salinity correction is required. For this, you have to measure and input the salinity of the measured medium first.
When the salinity correction is switched on, the [Sal] indicator is displayed in the measuring screen.
You can switch the salinity correction on or off and enter the salinity in the menu for calibration and measurement settings (see section

The integrated air pressure sensor of the MultiLab 4010-3 measures the current air pressure.During calibration, the air pressure correction function is automatically activated. For measurement, the air pressure correction is applied if the parameter oxygen saturation [%] is displayed and the Saturation local function is enabled.
ETTINGS FOR D.O. MEASUREMENT, page 92).
The current air pressure is displayed, when an IDS D.O. sensor is connected.

Stability control
(AutoRead)
& HOLD function
The stability control function (AutoRead) continually checks the stability of the measurement signal. The stability has a considerable impact on the reproduc­ibility of measured values.
The measured parameter flashes on the display
as soon as the measured value is outside the stability range
when the automatic Stability control is switched off.
Irrespective of the setting for automatic Stability control (see section 10.6.3 A
UTOMATIC STABILITY CONTROL, page 97) in the System menu, you can start a
measurement with Stability control manually at any time.
1. Freeze the measured value with <AR>.
The [HOLD] status indicator is displayed. The HOLD function is active.
You can terminate the Stability control function and the HOLD func­tion with <AR> or <M> at any time.
2. Using <ENTER>, activate the Stability control function manually.
The [AR] status indicator appears while the measured value is assessed as not stable. A progress bar is displayed and the display of the measured parameter flashes. As soon as a measured value meets the stability criteria, it is frozen. The [HOLD][AR] status indicator is displayed, the progress bar disappears and the display of the measured parameter stops flashing. The current measurement data is output to the interface. Measurement data meeting the stability control criterion is marked by AR.
You can prematurely terminate the Stability control function manu- ally with <ENTER> at any time. When the Stability control function is prematurely terminated, the current measurement data are out­put to the interface (PC, USB memory device or USB printer) with­out AutoRead info.
3. Using <ENTER>, start a further measurement with stability control.
or Release the frozen measured value again with <AR> or <M>. The [AR] status display disappears. The display switches back to the previous indication.

The minimum duration until a measured value is assessed as stable is the mon­itored time interval. The actual duration is mostly longer.

8.1.2 Measuring the temperature

For reproducible D.O. measurements, it is essential to measure the tempera­ture of the test sample.
IDS D.O. sensors measure the temperature with a temperature sensor inte­grated in the IDS sensor.

8.2 Calibration

8.2.1 Why calibrate?

D.O. sensors age. This changes the zero point (asymmetry) and slope of the D.O. sensor. As a result, an inexact measured value is displayed. Calibration determines and stores the current values of the zero point and slope.

8.2.2 When to calibrate?

When the calibration interval has expired
When your accuracy requirements are especially high
Routinely within the framework of the company quality assurance

8.2.3 Calibration procedures

The MultiLab 4010-3 provides 2 calibration procedures:
Calibration in water vapor-saturated air.
Calibration via a comparison measurement (e.g. Winkler titration according
to DIN EN 25813 or ISO 5813). At the same time, the relative slope is adapted to the comparison measurement by a correction factor. When the correction factor is active, the [Factor] indicator appears in the measuring window.
Calibration can be carried out either as a 1-point calibration or 2-point calibra­tion procedure.

9.1 Measuring

9.1.1 Measuring the conductivity

The sensor connection and the USB-B (device) interface are gal­vanically isolated. This facilitates interference-free measurements also in the following cases:
Measurement in grounded test samples
Measurement with several sensors connected to one
MultiLab 4010-3 in one test sample
1. Connect the conductivity sensor to the meter. The conductivity measuring window is displayed. The measuring cell and cell constant for the connected IDS conductivity sensor are automatically taken over.
Selecting the
displayed
measured parameter
2. If necessary, press <M> to select the measured parameter ϰ.
3. Immerse the conductivity sensor in the test sample.
You can switch between the following displays with <M>:
Conductivity [μS/cm] / [mS/cm]
Resistivity [Ω·cm] / [kΩ·cm] / [MΩ·cm]
Salinity SaL [ ] (
Total dissolved solids TDS [mg/l] / [g/l]
psu)
The factor to calculate the total dissolved solids is set to 1.00 in the factory. You can adjust this factor to meet your requirements in the range 0.40 ... 1.00. The factor is set in the menu for the parameter TDS.
Stability control
(AutoRead)
& HOLD function
78 ba76143e03 08/2013
The stability control function (AutoRead) continually checks the stability of the measurement signal. The stability has a considerable impact on the reproduc­ibility of measured values.
The measured parameter flashes on the display
as soon as the measured value is outside the stability range
when the automatic Stability control is switched off.
Page 79
MultiLab 4010-3 Conductivity
You can start the Stability control manually at any time, irrespective of the set- ting for automatic Stability control (see section 10.6.3 A
CONTROL, page 97) in the System menu.
UTOMATIC STABILITY
1. Freeze the measured value with <AR>. The [HOLD] status indicator is displayed. The HOLD function is active.
You can terminate the Stability control function and the HOLD func­tion with <AR> or <M> at any time.
2. Using <ENTER>, activate the Stability control function manually. The [AR] status indicator appears while the measured value is assessed as not stable. A progress bar is displayed and the display of the measured parameter flashes. As soon as a measured value meets the stability criteria, it is frozen. The [HOLD][AR] status indicator is displayed, the progress bar disappears and the display of the measured parameter stops flashing. The current measurement data is output to the interface. Measurement data meeting the stability control criterion is marked by AR.
Criteria for a stable
measured value
You can prematurely terminate the Stability control function manu- ally with <ENTER> at any time. When the Stability control function is prematurely terminated, the current measurement data are out­put to the interface (PC, USB memory device or USB printer) with­out AutoRead info.
3. Using <ENTER>, start a further measurement with stability control. or Release the frozen measured value again with <AR> or <M>. The [AR] status display disappears. The display switches back to the previous indication.
The Stability control function checks whether the measured values are stable within the monitored time interval.

9.1.2 Measuring the temperature

For reproducible conductivity measurements, it is essential to measure the temperature of the test sample.
IDS sensors measure the temperature with a temperature sensor integrated in the IDS sensor.

9.2 Temperature compensation

The calculation of the temperature compensation is based on the preset refer­ence temperature, 20 °C or 25 °C. It appears on the display as Tr20 or Tr25.
You can select one of the following temperature compensation methods:
Nonlinear temperature compensation (nLF) according to ISO 7888
Linear temperature compensation (lin) with adjustable coefficients of
0.000 ... 3.000 %
No temperature compensation (off)

9.3 Calibration

9.3.1 Why calibrate?

Aging slightly changes the cell constant, e. g. due to coatings. As a result, an inexact measured value is displayed. The original characteristics of the cell can often be restored by cleaning the cell. Calibration determines the current value of the cell constant and stores this value in the meter. Thus, you should calibrate at regular intervals.

9.3.2 When to calibrate?

After connecting a sensor
Routinely within the framework of the company quality assurance
When the cleaning interval has expired

9.3.3 Determining the cell constant (calibration in control standard)

You can determine the actual cell constant of the IDS conductivity sensor by calibrating with the control standard in the following range:
-1
0.450 ... 0.500 cm
(e.g. 4310, nominal cell constant 0.475cm
-1
)
The cell constant is determined in the control standard, 0.01 mol/l KCl.
In the delivery condition, the calibrated cell constant of the IDS sensor is set to
-1
0.475 cm
(4310 IDS conductivity sensor).
For this calibration procedure, the Type setting must be set to cal. Proceed as follows to determine the cell constant:
1. Connect the conductivity sensor to the meter.
2. In the measured value display, select the conductivity parameter with <M>.
3. Start the calibration with <CAL>. The cell constant that was calibrated last is displayed.
ba76143e03 08/2013 81
Page 82
Conductivity MultiLab 4010-3
4. Immerse the conductivity sensor in the control standard solution,
0.01 mol/l KCI.
5. Start the measurement with <ENTER>. The measured value is checked for stability (stability control). The [AR] status indicator is displayed. The measured parameter flashes.
6. Wait for the end of the measurement with stability control or take over the calibrated value with <ENTER>. The calibration record is displayed and output to the interface.
7. Switch to the measured value display with <ENTER>.

9.3.4 Calibration data

Displaying the cali-
bration record
The calibration record is automatically transmitted to the interface after calibrating.
The calibration data can be displayed and then output to the interface.
The calibration record of the last calibration is to be found under the menu item, Calibration / Calibration record. To open it in the measured value display, press the <CAL_> key.

10.6.2 Data storage

This menu contains all functions to display, edit and erase stored measured values.
Detailed information on the memory functions of the MultiLab 4010-3 are given in section 11 D
ATA STORAGE, page 102.

10.6.3 Automatic Stability control

The automatic Stability control (AutoRead) function continuously checks the stability of the measurement signal. The stability has a considerable impact on the reproducibility of measured values.
You can activate or switch off the automatic Stability control function (see section 10.6 S
ENSOR-INDEPENDENT SETTINGS, page 96).
The measured parameter flashes on the display
as soon as the measured value is outside the stability range
when you switch over between the measured parameters with <M>.
when the automatic Stability control is switched off.
