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 Measuring

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>.

& 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 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 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
[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.

Criteria for a stable

measured value

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 USB-B (USB Device, e.g. PC) or USB-A (USB Host, e.g.
USB memory device or USB printer) interface without AutoRead
info.

You can switch off the beep (see section 10.6 S

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-

If you wish to measure (or calibrate) without temperature sensor, proceed as
follows:

1. Measure the current temperature of the test sample.

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.

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).

7. Start the measurement with <ENTER>.

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

8. 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 display for the next buffer appears (voltage display).

9. If necessary, finish the calibration procedure as a single-point calibration

with <M>.
The calibration record is displayed.

For singl e-point calibration, the instrument uses the Nernst slope
(-59.2 mV/pH at 25 °C) and determines the zero point of the IDS­pH sensor.
