Sensor data from IDS sensors
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.
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 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 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 SENSOR INFO, page 17).
1.2.2Wireless 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.
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.
1.2.3IDS 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.
Installation shaft for The MultiLab 4010-3W has a recess into which the IDS adapter (4010-2/3 pH IDS adapter 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.

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.
1.2.4Automatic 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.

Stability control The stability control function (AutoRead) continually checks the stability of the (AutoRead) measurement signal. The stability has a considerable impact on the reproduc-
& HOLD function ibility 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 AUTOMATIC STABILITY CONTROL, page 110) in the System menu.
To start the Stability control function manually, the HOLD function must be enabled.

Criteria for a stable measured value
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.
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 SENSOR-INDEPEN-

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.

5.1.2Measuring 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, 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 indicator [TP ↑ ] is displayed in the measurement window of the IDS-pH adapter. The status indicator [TP ↓ ] is displayed in the measurement window of the IDS-pH sensor providing the temperature value.
Manual determination and input of the temperature.
The display of the temperature indicates the active temperature measuring mode:

If you wish to measure (or calibrate) without temperature sensor, proceed as follows:
1.Measure the current temperature of the test sample.
2.Set the temperature value with < >< >. or
In the <ENTER>//Man. temperature menu, set the temperature value with < >< >.
5.2pH calibration
5.2.1Why 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.

5.2.2When do you have to calibrate?
Routinely within the framework of the company quality assurance
When the calibration interval has expired
5.2.3Calibration 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 BUFFER 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.
5.2.4Carrying 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 SETTINGS 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).
