Suitable sensors are IDS pH sensors, IDS ORP sensors, IDS conductivity sensors and IDS D.O. sensors.

1.3.1 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

8 ba76141e07 08/2018

Page 9

MultiLab 4010-1W Overview

 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 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 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 4.1.5 S

ENSOR INFO, page 18).

1.3.2 Wireless operation of IDS sensors

With the aid of the adapters in the IDS WA Kit, IDS sensors with plug head connectors (variant P) can be wirelessly connected to your MultiLab 4010-1W. (MultiLab 4010-1 IDS: from software version V2.00)

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.

1.3.3 Automatic sensor recognition

The automatic sensor recognition for IDS sensors allows

 to operate an IDS sensor with different meters without recalibrating  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 series number.

 to hide menus automatically that do not concern this sensor

ba76141e07 08/2018 9

Page 10

Overview MultiLab 4010-1W

To be able to use the automatic sensor recognition, a meter that supports the automatic sensor recognition (e.g. MultiLab 4010-1W) 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.

5.2 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 Calibration procedure

The MultiLab 4010-1W 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

9.1.2 B

 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.

5.2.4 Carrying out automatic calibration (AutoCal)

Make sure that, in the menu for measurement and calibration settings (in the menu pH/ (see section 9.1.1 S

UFFER SETS FOR CALIBRATION, page 64).

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

<ENTER>/Calibration / Buffer), the correct buffer set is selected

ETTINGS FOR PH MEASUREMENTS, page 63).

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.

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 measuring range.

The following information is displayed:

1 Currently measured pH value (needle) 2 Marking lines for all nominal buffer values used with the last valid cali-

bration

3 Measuring range for which a valid calibration is available. Measured

values in this range are suitable for documentation.

4 Measuring range for which no valid calibration is available (shaded).

Measured values in this range are not suitable for documentation. Calibrate the meter with buffers covering this measuring range. If the current measured value is outside the calibrated range, this area is shaded stronger. If a measured value is outside the measuring range pH 0 - 14, overflow arrows are displayed at the left or right edge of the measuring range.

The limits of the calibrated range are determined by the buffers used for calibration:

Lower limit: Buffer with lowest pH value - 2 pH units Upper limit: Buffer with highest pH value + 2 pH units

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.

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).

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.

The general procedures for measuring, calibrating and setting are very similar with the various types of IDS-D.O. sensors. Any individual special features of the IDS-D.O. sensors are indicated in the general procedures.

The individual feature of the FDO 4410 is, for example, the high stability of its measuring characteristics during its total lifetime. Therefore, this sensor does not have to be calibrated regularly. It can simply be checked (FDO Check) instead.

A sensor with stirrer can only be operated while the meter is linepowered.

D.O. concentration 20 seconds D.O. saturation 20 seconds Temperature 15 seconds

∆ : better than 0.03 mg/l ∆ : better than 0.4 % ∆ : 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.

7.1.2 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.

7.2 FDO Check (checking the FDO 4410)

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

7.2.1 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.

7.2.2 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

7.2.3 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 beaker must be moist (not wet). Leave the sensor in the check and storage beaker long enough so it can adapt to the ambient temperature.

7. Switch to the measured value display with 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.

7.2.4 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 for the check of 98 to 102 % (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 5.4.1).

<M>.

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

value for the relative D.O. saturation (abbreviated: saturation) is

100 %. – 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.

7.3 Calibration

7.3.1 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 regularly calibrated. To detect changes of the sensor as early as possible, the FDO Check procedure can be useful (see section 7.2 FDO C

CHECKING THE FDO 4410), page 47).

(

7.3.2 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.

7.3.3 Calibration procedures

The MultiLab 4010-1W 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 multiplier. When

the correction multiplier is active, the [Factor] indicator appears in the mea-

suring window.

For both calibration procedures, an additional Zero calibration is possible (see section 7.3.6 Z

ERO CALIBRATION, page 52).

7.3.4 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.

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

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

8.3 Calibration

8.3.1 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.

8.3.2 When to calibrate?

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

8.3.3 Calibration procedure

The MultiLab 4010-1W provides 2 calibration procedures:  Determining the cell constant

 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.

8.3.4 Determining the cell constant (calibration in the check- and cali-

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 8.3.5 S
