4010-3W

1 Overview

1.1 MultiLab 4010-3W

The MultiLab 4010-3W meter enables you to perform measurements (pH, U,
ISE, conductivity, and dissolved oxygen) quickly and reliably.

The MultiLab 4010-3W provides the maximum degree of operating comfort,
reliability and measuring certainty for all applications.

The MultiLab 4010-3W supports you in your work with the following functions:

 proven calibration procedures
 automatic stability control (AR)
 automatic sensor recognition
 CMC (continuous measurement control)
 QSC (sensor quality control).

1 Keypad (antibacterial)
2 Display
3 Connectors

Due to its antibacterial properties, the keypad of the
MultiLab 4010-3W is especially suitable for applications in an envi­ronment where hygiene is important (see

DATA, page 135).

1.2 Sensors

SECTION 15.2 GENERAL

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

ba76194e03 07/2018 7

Overview MultiLab 4010-3W

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 serial number

 Calibration data
 Measurement settings

The calibration data are updated in the IDS sensor after e ach 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 serial number of the selected sensor with the [

i

] 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).

1.2.2 Wireless operation of IDS sensors

With the aid of the adapters in the IDS WA Kit, IDS sensors with plug head
connectors (variant W) can be wirelessly connected to your MultiLab 4010-3W.

Installation shaft for

IDS adapter

Two adapters, one at the IDS meter (IDS WA-M) and one at the sensor (IDS
WA-S), replace the sensor cable with an energy-saving Bluetooth LE radio
connection.

Further information on the wireless operation of IDS sensors:

 Web resources
 Operating manual of the IDS WA Kit.

1.2.3 IDS adapter for analog sensors

With the aid of an IDS adapter, you can also operate analog sensors
on the MultiLab 4010-3W. The combination of the IDS adapter and analog
sensor behaves like an IDS sensor.

The YSI 4011 adapter can be used to connect a YSI 5010 BOD probe (any vari­ation) to a IDS sensor port on the MultiLab 4010-3W instrument.

The MultiLab 4010-3W has a recess into which the IDS adapter (4010-2/3 pH
Adapter DIN or 4010-2/3 pH Adapter BNC) available as an accessory can be
permanently mounted.

In the MultiLab 4010-3W, the IDS adapter replaces a digital input (channel 2)
with a socket for an analog pH sensor (DIN or BNC plug) and a temperature
sensor.

MultiLab 4010-3W Overview

Information on available IDS adapters is given on the Internet.
Detailed information on the IDS adapter is given in the operating
manual
of the adapter.

1.2.4 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 serial 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 serial 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 4010-3W) 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.

5.1.1 Measuring the pH value

The sensor connection and the USB-B (USB Device) interface are
galvanically insulated. This facilitates interference-free measure­ments also in the following cases:

 Measurement in grounded test samples
 Measurement with several sensors connected to one

MultiLab 4010-3W 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>.

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 set­ting for automatic Stability control (see section 10.6.3 A

CONTROL, page 110) in the System menu.

To start the Stability control function manually, the HOLD function must be
enabled.

You can terminate the HOLD function and the Stability control 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

the display of the measured parameter stops flashing, and there is a
beep.
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. If the Stability control function is
prematurely terminated, the current measurement data are output

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 a n
IDS-pH adapter, there are the following ways to measure the temperature of
the test sample:

 Measurement of the temperature with the integrated temperature sensor

of an IDS sensor.
If the measured value is taken over from an IDS sensor, the status indi-

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.

ba76194e03 07/2018 27

pH value MultiLab 4010-3W

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 Calibration procedure

The MultiLab 4010-3W provides 2 calibration procedures:
 Automatic calibration (AutoCal)

The buffer solutions used are automatically identified during the calibration
procedure. The relevant nominal values are used automatically.
Prerequisite: The buffer set used has been set in the meter (see section

10.1.2 B

UFFER SETS FOR CALIBRATION, page 99).

 Manual calibration (ConCal)

Any buffer solutions can be used. The nominal values of the buffer solutions
are manually entered by the user during the calibration procedure.

For most applications, automatic calibration (AutoCal) is the safest
and most convenient way of executing a calibration.

5.2.4 Carrying out automatic calibration (AutoCal)

Make sure that, in the menu for measurement and calibration settings (in the
menu pH/<ENTER>/Calibration / Buffer), the correct buffer set is selected (see
section 10.1.1 S

ETTINGS FOR PH MEASUREMENTS, page 97).

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>.

The calibration display for the first buffer appears (voltage display).

5.2.8 Continuous measurement control (CMC function)

The Continuous Measurement Control (CMC function) facilitates to evaluate
the current measured value instantly and definitely.

After each successful calibration the scale of the pH measuring range is
displayed in the measured value display. Here you can very clearly see
whether or not the current measured value is in the calibrated part of the

5.2.9 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.

1QSC scale

The double arrow on the QSC scale indicates the current sensor eval­uation

Sensor evaluation

with / without
QSC function

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). clean, calibrate or replace the
sensor).

With QSC function Without QSC function (sensor

symbol)

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 from 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 cali-

ba76194e03 07/2018 39

pH value MultiLab 4010-3W

01.09.2017 08:00

bration 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

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.

1. Prepare for calibration the meter, sensor and the buffer solutions of the
QSC-Kit.

2. Open the menu for measurement settings with <ENTER>.

3. 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.

4. Start the measurement with <ENTER>.
Calibration with the buffers of the QSC-Kit is done like a normal three­point calibration (see section 5.2.4 C

TION (AUTOCAL), page 28).

ARRYING OUT AUTOMATIC CALIBRA-

5. 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 deter-

Carrying out a QSC

control calibration

A QSC control calibration can, e.g. be useful if the sensor evaluation noticeably
changed (after some normal calibrations).

You can carry out QSC control calibrations at greater intervals than normal cali­brations.

1. Prepare for calibration the meter, sensor and the buffer solutions of the
QSC-Kit.

2. Open the menu for measurement settings with <ENTER>.

3. In the QSC menu, select Control 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 control calibration.

4. Start the measurement with <ENTER>.
Calibration with the buffers of the QSC-Kit is done like a normal three­point calibration (see section 5.2.4 C

TION (AUTOCAL), page 28).

ARRYING OUT AUTOMATIC CALIBRA-

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
control calibration.

Incorrect calibration of ion sensitive electrodes will result in incor­rect measured values. Calibrate regularly before measuring.

For precise ISE measurements the temperature difference
between measurement and calibration should not be greater than
2 °C. Therefore, adjust the temperature of the standard and
measuring solutions accordingly. If the temperature difference is
greater the [TempErr] warning appears in the measured value

following criteria can be adjusted in the menu for measurement and calibration
settings (menu <ENTER>/ISE setup/AutoRead criterion):

 high: highest reproducibility
 medium: medium reproducibility
 low:lowest reproducibility

Increasing reproducibility also causes the response time to
increase until a measured value is evaluated as stable.

7.1.2 Measuring the temperature

For reproducible ion-selective measurements, it is essential to measure the
temperature of the test sample.

Most 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 a n
IDS-pH adapter, there are the following ways to measure the temperature of
the test sample:

 Measurement of the temperature with the integrated temperature sensor

of an IDS sensor.
If the measured value is taken over from an IDS sensor, the status indi-

dow of the IDS-pH sensor providing the temperature value.

 Manual determination and input of the temperature.

The measuring instrument recognizes whether a suitable sensor is connected
and automatically switches on the temperature measurement.

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 (if possible), 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 in the measurement determines the concentration of the calibration
standards.

For calibration with 3 or more points, the standards have to be selected either
in increasing or decreasing order.

1. Connect the ISE electrode to the meter.
The pH/mV/ISE measuring window is displayed.

2. Keep the standard solutions ready.

3. If necessary, measure the temperature of the standard solutions with a
thermometer.

4. In the measured value display, select the ISE measuring window with

><

5. Specify the ion type in the ISE setup/Ion type menu as necessary.

6. If necessary, change the unit of the measurement result and calibration
standards in the ISE setup/Unit menu.

8.1 Measuring

8.1.1 Measuring D.O.

The sensor connection and the USB-B (USB Device) interface are
galvanically insulated. This facilitates interference-free measure­ments also in the following cases:

 Measurement in grounded test samples
 Measurement with several sensors connected to one

MultiLab 4010-3W in one test sample

1. Connect the IDS-D.O. sensor to the meter.

The D.O. measuring screen is displayed.

2. If necessary, select the measured parameter with <M>.

3. Check or calibrate the meter with the sensor.

Only in special cases does the FDO 4410-D.O. sensor require cal­ibration. Regular FDO Checks are sufficient.

4. Immerse the D.O. sensor in the test sample.

Selecting the

displayed

measured parameter

You can switch between the following displays with <M>:

 D.O. concentration [mg/l]
 D.O. saturation [%]

Salinity correction When measuring the D.O. concentration [mg/l] of solutions with a salt content

of more than 1 psu, a salinity correction is required. For this, you have to me a­sure and input the salinity of the measured medium first.

68 ba76194e03 07/2018

When the salinity correction is switched on, the [Sal] indicator is displayed in
the measuring screen.

MultiLab 4010-3W Dissolved oxygen

You can switch the salinity correction on or off and enter the salinity
in the menu for calibration and measurement settings (see section

& HOLD function

The integrated air pressure sensor of the MultiLab 4010-3W measures the
current air pressure. During calibration, the air pressure correction function is
automatically activated. While the parameter oxygen saturation [%] is
displayed, the air pressure correction is applied if the DO % Saturation local
function is active.

The current air pressure is shown on the display when an IDS oxygen sensor
is connected.

The air pressure correction (function DO % Saturation local) is
switched on or off in the menu for calibration and measurement set­tings (see section 10.4.3 DO % S

ATURATION LOCAL, page 106).

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

UTOMATIC STABILITY CONTROL, page 110) in the System menu, you can start a

A
measurement with Stability control manually at any time.

Hold function

To start the Stability control function manually, the HOLD function must be
enabled.

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,
the display of the measured parameter stops flashing, and there is a
beep.
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. If the Stability control function is
prematurely terminated, the current measurement data are output
to the interfaces USB-B (USB Device, e.g. PC) and USB-A (USB
Host, e.g. USB memory device or USB printer) without AutoRead
info.

You can switch off the beep (see section 10.6 S

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 FDO Check (checking the FDO 4410)

The sensor is checked in water vapor-saturated air in the check and storage
vessel FDO Check.

8.2.1 Why should you check the sensor?

With the FDO Check procedure you can find out in a simple manner whether
the FDO 4410 D.O. sensor should be cleaned or calibrated.

8.2.2 When should you check the sensor?

Checking can be useful in the following cases:
 When the check interval has expired

(the [check] status indicator is displayed).

 If the measured values seem to be implausible
 If you assume that the sensor cap is contaminated or at the end of its lifetime
 After the sensor cap was exchanged
 Routinely within the framework of the company quality assurance

8.2.3 Perform a FDO Check

Proceed as follows to carry out the FDO Check:

1. Connect the D.O. sensor to the meter.

2. Place the D.O. sensor in the FDO Check check and storage vessel.

3. Close the check and storage vessel FDO Check.

The sponge in the check and storage vessel must be moist (not
wet). Leave the sensor in the check and storage vessel long
enough so it can adapt to the ambient temperature (min. 15 min­utes).

4. In the menu for measurement and calibration settings (<ENTER> /

FDO Check / Start FDO Check), start the FDO Check.
The meter switches to the display of %.
During the FDO Check the DO % Saturation local function is automat­ically activated.

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 (beep,

[HOLD][AR] status indicator) or take over the calibrated value with
<ENTER>.
The measured value is frozen.

7. Switch to the measured value display with <M>.

The check measurement is not documented.
After the FDO Check the DO % Saturation local function is automatically
reset to the setting before the FDO Check.

8.2.4 Evaluation

The evaluation is based on the accuracy required and de fined by the user (e.g.
± 2 %). Together with the nominal value (100 %) this results in a validity scope
(98 to 102 %) for the check (see example).

If the measured value is within the validity scope, no cleaning or user calibration
is required.

If the measured value is outside the validity scope, the sensor shaft and
membrane should be cleaned, and the check should then be repeated (see
section 8.2.3 P

ERFORM A FDO CHECK, page 71).

Example:

– Required accuracy: ± 2 %.
– In water vapor-saturated air or in air-saturated water, the nominal value is

100 % (while taking into account the local air pressure).
– Therefore, the validity scope is 98 ... 102 %
– The check resulted in a measured value of 99.3 %

The measurement error is within the specified validity scope.
No cleaning or user calibration is required.

MultiLab 4010-3W Dissolved oxygen

8.3 Calibration

8.3.1 Why calibrate?

D.O. sensors age. Aging changes the zero point 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.

The FDO 4410 D.O. sensor ages so little it does not have to be reg-
ularly calibrated.
To detect changes of the sensor as early as possible, the
FDO Check procedure can be useful (see section 8.2 FDO C

CHECKING THE FDO 4410), page 71).

(

8.3.2 When to calibrate?

 If your evaluation of the FDO Check suggests calibrating (only FDO 4410)
 When the calibration interval has expired

HECK

 When your accuracy requirements are especially high
 Routinely within the framework of the company quality assurance
 After a Zero Calibration.

8.3.3 Calibration procedures

The MultiLab 4010-3W 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 multiplier is active, the [Factor] indicator appears in the measuring

window.

For both calibration procedures, an additional Zero Calibration is
possible (see section 8.3.6 Z

ERO CALIBRATION, page 76).

8.3.4 Calibration in water vapor-saturated air

For this calibration procedure, the Comparison meas. setting must be set to off
in the Calibration menu.

As the calibration vessel use a BOD bottle that contains a small amount of
clean water (approx. 40 ml). The sensor must not be immersed in the water.

ba76194e03 07/2018 73

Dissolved oxygen MultiLab 4010-3W

01.09.2017 08:00

To calibrate the FDO 4410, use the calibration and storage vessel
FDO Check. The sponge in the check and storage vessel must be
moist (not wet).

Proceed as follows to calibrate the D.O. sensor:

1. Connect the D.O. sensor to the meter.

2. Put the D.O. sensor into the calibration vessel.

3. For FDO 4410 with the check and storage vessel FDO Check:

Close the check and storage vessel FDO Check.

Leave the sensor in the calibration vessel or check and storage
vessel (FDO 4410) long enough (at least 15 minutes) until the air is
saturated with water vapor and the sensor has adapted to the
ambient temperature.

4. Start the calibration with <CAL>.

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 measurement with stability control to be finished (beep,

[HOLD][AR] status indicator).
The calibration record is displayed and output to the interface.

7. Switch to the measured value display with <ENTER>.

8.3.5 Calibrating with Comparison meas. (e.g. Winkler titration)

With the calibration procedure Comparison meas., the measured value of the
sensor is adjusted to the nominal value of a comparison solution via a correc-

tion factor. The current correction factor is documented in the sensor menu (i
Factor = x.xxx) and in the calibration record.

For this calibration procedure, the Comparison meas. setting must be set to on
in the Calibration menu.

Proceed as follows to calibrate the D.O. sensor:

1. Connect the D.O. sensor to the meter.

2. Immerse the D.O. sensor in the reference solution.

3. Start the calibration with <CAL>.

4. Start the measurement with <ENTER>.

The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
flashes.

5. Wait for the measurement with stability control to be finished (beep,

>, set the correction factor to adjust the displayed value
to the nominal value (value of the comparison measurement). Subse­quently take over the adjustment with <ENTER>.
The meter switches to the measured value display.
The status display [Factor] is active.

8.3.6 Zero Calibration

With a Zero Calibration, the zero point of the sensor is redetermined by cali­brating in a zero solution.

For most applications, an additional Zero Calibration is not required and not
recommended. Only with very rare applications can the accuracy of a calibra­tion be improved if a Zero Calibration was carried out before.

The FDO 4410 D.O. sensor ages so little it does not have to be zero
point calibrated.
A zero point calibration is not allowed for this sensor.

The Zero Calibration is best carried out prior to calibrating with a calibration
procedure (e.g. calibration in water vapor-saturated air or calibration with
comparison measurement).

1. Connect the D.O. sensor to the meter.

2. Place the D.O. sensor in a solution that does not contain any dissolved
oxygen.

A solution not containing any dissolved oxygen can be prepared by
dissolving approx. 8 to 10 g sodium sulfite (Na

) in 500 ml tap-

2SO3

water. Carefully mix the solution. It may take up to 60 minutes until
the solution is free of oxygen.

3. In the menu for measurement and calibration settings (<ENTER> / Cal-
ibration / Zero Calibration), start the Zero Calibration.
The calibration point for the measured value 0 (DO Zero) is displayed.

Stability control

(AutoRead)

& HOLD function

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.

You can start the Stability control manually at any time, irrespective of the set­ting for automatic Stability control (see section 10.6.3 A

CONTROL, page 110) in the System menu.

UTOMATIC STABILITY

To start the Stability control function manually, the HOLD function must be
enabled.

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 va lue 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. If the Stability control function is
prematurely terminated, the current measurement data are output
to the interfaces USB-B (USB Device, e.g. PC) and USB-A (USB

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

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 coefficient
 No temperature compensation (off)

The reference temperature and temperature compensation are set
in the menu for the parameter, conductivity (see section 10.5.1 S

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?

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

9.3.3 Calibration procedure

The MultiLab 4010-3W provides 2 calibration procedures:
 Determining the cell constant

Calibration in the check- and calibration standard 0.01 mol/l KCl (1413 µS/
cm @25 °C)
Safe and simple calibration procedure for IDS conductivity sensors with a

-1

cell constant in the range 0.450 ... 0.500 cm

.

 Determining the cell constant

Calibration with freely selectable check- and calibration standard
Comprehensive and flexible calibration procedure for all IDS conductivity
sensors, irrespective of the cell constant.

Which calibration procedures can be used depends on the conductivity sensor
used. The menu for measurement settings automatically displays only those
settings and calibration procedures that are available for the sensor.

With conductivity sensors for which a cell constant was set, no
sensor symbol appears on the display.
If a calibration interval was specified, it is not active.

MultiLab 4010-3W Conductivity

01.09.2017 08:00

9.3.4 Determining the cell constant (calibration in the check- and cali­bration standard)

For this calibration procedure, IDS conductivity sensors with a cell constant in
the range 0.450 ... 0.500 cm

-1

are suitable, e.g. 4310.

IDS conductivity sensors with other cell constants are unsuitable for this simple
calibration procedure. As an alternative, you can manually determine the cell
constant and adjust it in the menu (see section 9.3.5 S

STANT (CALIBRATION WITH FREELY SELECTABLE CHECK- AND CALIBRATION STAN-
DARD), page 94).

ETTING THE CELL CON-

You can determine the actual cell constant of the IDS conductivity sensor within
a valid range (e.g. 4310: 0.450 ... 0.500 cm

-1

).

The cell constant is determined in the check- and calibration standard 0.01 mol/
l KCl (1413 µS/cm @ 25 °C).

In the default condition, the calibrated cell constant is set to the nominal cell

-1

constant of the IDS sensor (e.g. 4310: 0.475 cm

).

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.

4. Immerse the conductivity sensor in the check- and calibration standard

(e.g. 4310: 0.01 mol/l KCl (1413 µS/cm @ 25 °C)) .

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 (beep,

[HOLD][AR] status indicator) 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>.

9.3.5 Setting the cell constant (calibration with freely selectable check- and calibration standard)

You can set within a valid range the cell constant of the IDS conductivity sensor
(setting range: see sensor operating manual).

With a freely selectable check- and calibration standard with known conduc­tivity nominal value (within the measuring range of the sensor), you can exactly
adjust the cell constant to the check- and calibration standard by the changing
conductivity value displayed.

In the default condition, the cell constant is set to the nominal cell constant of
the IDS sensor.

For this calibration procedure, the Type setting must be set to man. Proceed as
follows to set the cell constant:

1. Connect the conductivity sensor to the meter.

2. In the measured value display, select the conductivity parameter with

<M>.

3. Open the menu for measurement settings with <ENTER>.

4. Select the setting of the cell constant

(4310: Menu Type: man and Man. cell const.

The current conductivity value is displayed in the status line.

5. Set the suitable temperature compensation and reference temperature

for the check- and calibration standard.

6. Immerse the conductivity sensor in the check- and calibration standard.

Wait for a stable measured value.

7. Using <

Limit monitoring With the Limit monitoring function you define the measured

values whose exceeding is signaled. An acoustic signal
sounds, and at the same time a message is output to the
USB interface.
You can switch on or off the acoustic signal in the System

YSTEM, page 109).
