1.3 Sensors

A measuring system ready to measure consists of the MultiLab 4010-1 meter and a suitable sensor.

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 ba76141e03 03/2014

Page 9

MultiLab 4010-1 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 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 4.1.5 S

ENSOR INFO, page 18).

1.3.2 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 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 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 4010-1) 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.

5.2.1 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 9.1.1 S

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.

5.2.7 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

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.

1QSC scale

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

Sensor evaluation

with / without QSC function

QSC calibration The QSC function is enabled by once carrying out an additional three-point cali-

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).

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 the QSC initial calibration.

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.

Rough grading of the sensor evaluation (4 grades)

A theoretical reference value is used for all sensors

Greater tolerances for zero point and slope when using commercial buffer sets

D.O. sensors age. This changes the zero point and slope of the IDS 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.

7.2.2 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

7.2.3 Calibration procedures

The MultiLab 4010-1 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 screen.

Calibration can be carried out either as a 1-point calibration or 2-point calibration procedure.

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?

 After connecting a sensor

 Routinely within the framework of the company quality assurance

 When the cleaning interval has expired

8.3.3 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:

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
