12 C96IB001ML-A

• Do not leave sample/rinsing containers uncovered. Clean all spillages immediately.

• Make sure that the setup location is sufficiently ventilated. The environment of SG-Ultra Max must be kept free of flammable gases and vapors.

• Supply a fire extinguisher.

3 Measuring Principle

Definition of density

The density ρ of a sample is defined as its mass divided by its volume:

Density is a temperature-dependent measuring unit.

The oscillating U-tube principle

The sample is introduced into a U-shaped borosilicate glass tube that is being excited to vibrate at its characteristic frequency electronically. The characteristic frequency changes depending on the density of the sample. Through determination of the characteristic frequency the density of the sample can be calculated. Due to the temperature dependency of the density value, the temperature of the sample has to be determined precisely.

Concentration measurement

In binary mixtures, the density of the mixture is a function of its composition. Thus, by using density/concentration tables, the density value of a binary mixture can be used to calculate its composition.

This is also possible with so-called quasi binary mixtures. These are mixtures containing two major components and some additional ones which are present in very small concentrations compared to the two main components. Many decarbonated soft drinks, for example, can be considered to be quasi binary mixtures of sugar in water because the concentration of flavors and acids are very small compared to sugar and water. Thus, the sugar concentration can be measured with a density meter.

4 SG-Ultra Max - an Overview

The portable density meter SG-Ultra Max measures the density of liquids in g/cm3 or kg/m3 according to the oscillating U-tube principle. Apart from density you can select various further measuring units (relative density, density at reference temperature, concentrations). A temperature sensor measures the sample temperature right at the measuring cell. The temperature is displayed and can be used internally for automatic temperature compensation of the density reading if required.

Owing to the lightweight and compact design one can easily perform measurements of usually difficult accessible samples. The backlight of the display ensures clear visibility of results, even in dark surroundings. The backlight of the oscillator at the same time enables to observe the filling process in detail.

Samples are filled into the measuring cell using the built-in pipette-style pump or a syringe. You can allocate sample IDs to your samples for easier identification. You can also define and store different measuring methods allowing acceleration of repeatedly performed standard measurements.

SG-Ultra Max is operated via seven keys. 1024 measuring data including date, time and sample ID can be stored in the memory of the SG-Ultra Max density meter and can be recalled, exported to a PC or printed later. The transfer of the stored measuring data to a printer or PC is done wireless using an infrared interface (IrDA).

The product version SG-Ultra Max Tag&Log is additionally equipped with an RFID interface. Via this interface, sample IDs and/or methods can be uniquely linked to an RFID tag. Later on, by reading the RFID tag, you can switch fast and easily between different sample IDs and methods which further increases the efficiency of your measuring process.

The intrinsically safe product versions SG-Ultra Max Ex and SG-Ultra Max Ex Petrol (ATEX marking II 2 G Ex ib IIC T4) are suitable for use within potentially explosive areas. The SG-Ultra Max Ex is ideal for chemical applications and measuring battery acid. The SG-Ultra Max Ex Petrol comes with a special housing for petrochemical applications, esistant to petrols and similar solvents.

The product versions SG-Ultra Max Ex and SG-Ultra Max Ex Petrol are also equipped with an RFID interface.

10 Performing a Measurement

General instructions for measuring

• Make sure that the measuring cell is filled free from gas bubbles. Possible reasons for gas bubbles in the measuring cell are:

• Gas bubbles in the sample

• Leaky connection of the filling tube, the pump or the screw plug

• Make sure that the measuring cell is fully filled.

• Make sure that the sample temperature does not deviate too strongly from the ambient temperature.

WARNING

Handling samples with temperatures of more than 70 °C bears the danger of heavy burns.

• Make sure you wear protective clothes or ensure alternative protection from burns when handling high temperature samples.

WARNING

SG-Ultra Max not insulated against high voltages. Measuring samples under high voltage (e.g. in energized battery banks) bears the risk of an electric shock.

• Define appropriate testing procedures and safety measures to protect yourself from any electric shock.

NOTICE Before performing a measurement, make sure that the wetted parts

are resistant to the sample (see Chapter 16).

NOTICE Sample containing dissolved CO

will cause bubbles within the

measuring cell with the effect of invalid measurement results. Make sure your sample is degassed carefully. Degassing a sample can be done by:

• boiling the sample for several minutes,

• stirring the sample for 5 to 15 minutes until no bubbling occurs any more or

• putting the sample for approximately 5 to 10 minutes into an ultrasonic bath.

40 C96IB001ML-A

10.4 Selecting the Measurement Mode

SG-Ultra Max provides three different measurement modes - "Precise", "Fast" and "Manual". According to the measurement mode selected, different stability criteria have to be fulfilled before the result is stored. The stability criterion is always related to the temperature:

• When the measurement mode "Precise" is selected, the result is stored as soon as the measured temperature value stays within 0.2 K for 10 seconds. This measurement mode delivers the most accurate results, but may take a longer time in case the sample temperature differs greatly from the ambient temperature.

• When the measurement mode "Fast" is selected, the result is stored as soon as the measured temperature value stays within 0.4 K for 10 seconds. This measurement mode delivers quicker results than the "Precise" mode, but as the density is highly temperature dependent, the measured result is not that accurate.

• The measurement mode "Manual" enables you to decide yourself when to store your measurement result. The result is stored immediately after pressing the <Store> key on the backside of the instrument.

1. Press <Menu> and select "Measurement Mode".

2. Select the preferred setting (Precise, Fast, Manual) and press <Save>.

10.5 Using the RFID Function (Only for Versions with RFID Interface)

The product versions SG-Ultra Max Tag&Log, SG-Ultra Max Ex and SG-Ultra Max Ex Petrol are equipped with an RFID interface, enabling you to uniquely link an RFID tag to a method and/or sample ID. The RFID tag can either be allocated to a sample ID and/ or method on the instrument or can be programmed accordingly.

10.5.1 Preconditions for Using RF ID

The reading range of the RFID receiver integrated in SG-Ultra Max is about 2 cm. The RFID tag has to be situated within this area to enable data exchange with SG-Ultra Max.

TIP The larger the diameter of a tag, the larger is the reading range.

C96IB001ML-A 41

The following types of RFID tags were tested by EEPS for usage. Both tested tag types are available at EEPS.

Furthermore, several other LF tags (low frequency tags, 125 kHz) may be compatible in the "Read only" mode. See Chapter 10.5.5 for details on how to check RFID tags for compatibility.

10.5.2 Allocating RFID Tags

Allocation of an RFID tag is done by reading the unique identification number of the tag via the RFID interface of SG-Ultra Max and by allocating this identification number to a method and/or sample ID on the instrument. Allocation is done exclusively on the instrument and no programming of the RFID tag is done. For this, RFID tags with read-only functionality are sufficient.

You can allocate an RFID tag during entering a new method (see Chapter 10.2.1) or sample ID (see Chapter 10.3.1) as well as during editing a method (see Chapter

10.2.3) or sample ID (see Chapter 10.3.3).

Measuring methods and sample IDs that have an allocated RFID tag are marked with the RFID symbol .

1. Go to the corresponding menu as described in the appropriate chapter.

2. Hold the RFID tag to the RFID interface of the instrument until the RFID tag number is displayed.

3. You can now enter further characters, if required.

4. Navigate to the tick symbol using the arrow keys and press <Save>.

An RFID tag may only be allocated to one method and/or sample ID. If you try to allocate an RFID tag to more than one method and/or sample ID, the message "RFID in use" is displayed. In this case, choose another RFID tag for this method or sample ID.

If you try to allocate an RFID tag a second time to the same sample ID or method, "RFID matches" is displayed.

42 C96IB001ML-A

10.5.3 Programming RFID Tags

Besides allocation of RFID tags to sample IDs and/or methods on the instrument (see Chapter 10.5.2), SG-Ultra Max versions with RFID interface provide the option to write the sample ID and/or method to an RFID tag. Using this programming feature makes you independent regarding the amount of sample IDs and methods used as no sample ID list or method list has to be stored permanently on the instrument. One method and/ or one sample ID can be stored on the RFID tag.

1. Enter the sample IDs (see Chapter 10.3.1) and/or methods (see Chapter 10.2.1) or import a sample ID list (see Chapter 10.3.2) and/or method list (see Chapter

10.2.2) from your PC.

2. Press <Menu> and select "Sample-ID > Send ID to RFID" or "Methods > Send Method to RFID".

The sample ID list or method list appears on your screen.

3. Move the cursor to the first sample ID or method you want to send to an RFID tag using the arrow keys.

4. Hold the RFID tag to the RFID interface of the instrument until the RFID tag number is displayed.

The tag is now programmed with the according sample ID or method.

5. Repeat this procedure for the other sample IDs and/or methods you want to store on other RFID tags.

6. After all sample IDs and/or methods have been sent to RFID tags, you can delete the sample ID list (see Chapter 9.3.5) and/or method list (see Chapter

9.2.5) from the instrument.

10.5.4 Erasing RFID Tags

In case a mistake occurred during programming of a tag or if you want to use the tag for another sample ID and/or method, you have the possibility to delete the sample ID and/or method from the tag.

1. Press <Menu> and select "Setup > RFID > Erase RFID".

2. Hold the RFID tag to the RFID interface of the instrument until "RFID Erased" is displayed.

C96IB001ML-A 43

10.5.5 Reading RFID Information

Reading the RFID information helps you to identify an RFID tag in case the tags got mixed up, or you want to check if the tag was programmed correctly, or you want to check the compatibility of a tag type with SG-Ultra Max versions with RFID interface.

The RFID information states details about:

• tag number

• tag type (writeable yes/no)

• sample ID allocated to or stored on the tag

• method allocated to or stored on the tag

1. Press <Menu> and select "Setup > RFID > RFID Information".

2. Hold the RFID tag to the RFID interface of the instrument until the RFID information is displayed.

3. Hold the next RFID tag to the RFID interface of the instrument until the RFID information is displayed or exit the "RFID Information" menu.

10.5.6 Selecting a Method and/or Sample ID via RFID

This way of selection is only available if one or more methods and/or sample IDs have been allocated to an RFID tag (see Chapter 10.5.2) or if one or more RFID tags have been programmed with a method and/or sample ID (see Chapter 10.5.3).

1. Allocate the RFID function to the softkey (see Chapter 8.7)

2. When the instrument displays the main screen, press the <RFID> softkey.

The message "Reading RFID" is displayed.

3. Hold the allocated or programmed RFID tag to the RFID interface of the instrument.

TIP If you want to check the compatibility of a tag type to the instrument, see if

the RFID number ("RFID") is stated within the RFID information. In case it is displayed, the tag is compatible, if it is not displayed, the tag type is not compatible.

TIP When reading an RFID tag, which is neither allocated to a sample ID or

method on the instrument nor programmed with a sample ID or method, the unique tag number will be used as sample ID automatically.

A-LM100BI69C44

The method and/or sample ID allocated to or stored on the RFID tag will automatically be used for the following measurements.

13 Readjustment

If the measuring cell is not sufficiently cleaned, residue can form in the measuring cell. This can be noticed if the density values for deionized water begin to deviate. Therefore, perform regularly check measurements with deionized water.

If the density values for water deviate by more than ±0.001 g/cm

at the given temperature from the table values (see Appendix A), then a readjustment is required. A readjustment is only possible if the calculated difference between the measured and the theoretical value is smaller than 0.01 g/cm

and the temperature of the water

is between 15 and 25 °C.

13.1 Check Measurement

1. Clean the measuring cell as described in Chapter 11.1 and rinse the measuring

cell until no more solvent residues are present.

2. Select the measuring unit "Density" (see Chapter 10.1).

3. Fill the measuring cell with deionized water and perform a measurement (see

Chapter 10.6 and 10.7).

4. Compare the measured density value with the table values (see Appendix A).

5. If the measured density value deviates more than ±0.001 g/cm

from the table

value, perform a readjustment.

13.2 Water Adjustment

One option is to readjust using deionized water.

1. Clean the measuring cell as described in Chapter 11.1 and rinse the measuring

cell until no more solvent residues are present.

2. Press <Menu> and select "Adjustment > Water Adjustment".

3. Fill the measuring cell with deionized water at approx. 20 °C (15 to 25 °C)

without bubbles.

4. Confirm with <OK> that the measuring cell is filled with deionized water.

The density value of the filled deionized water is now measured and compared with the adjustment data. The display shows the calculated deviation (Delta) in g/cm

5. Press <OK> to activate the new adjustment.

C96IB001ML-A 57

13.3 Custom Adjustment

You can also use any other reference liquid with a known density at 20 °C and known temperature coefficient for your readjustment.

We recommend using the customer adjustment e.g. if you measure only liquids in a specific density range (e.g. high density) and want to yield more accurate results in this range.

1. Clean the measuring cell as described in Chapter 11.1 and rinse the measuring cell until no more solvent residues are present.

2. Press <Menu> and select "Adjustment > Custom Adjustment".

3. Fill the measuring cell with reference liquid at approx. 20 °C (15 to 25 °C) without bubbles.

4. Confirm with <OK> that the measuring cell is filled with reference liquid.

5. Enter the density of your reference liquid at the stated reference temperature using the arrow keys and press <Save>.

6. Enter the temperature coefficient of your reference liquid and press <Save>.

The density of the filled reference liquid is now measured and compared with the entered density for the reference liquid at 20 °C. The display shows the calculated deviation (Delta) in g/cm

7. Press <OK> to activate the new adjustment.

13.4 Defining an Offset

You can define an offset for your measurement. This is automatically added to each measured value. The offset value always refers to the current measuring unit and is deleted when you change to another measuring unit. If you have selected a method, the set offset is saved with the method.

1. Press <Menu> and select "Adjustment > Custom Offset".

2. Enter your offset value and press <Save>.

TIP The offset value saved with a method can also be changed later on.

13.5 Restoring to Factory Adjustment

If you want to undo all your adjustments, you can restore the factory adjustment.

1. Press <Menu> and select "Adjustment > Factory Adjustment".

The display shows: "Are you sure that you want to reset to factory adjustment?"

2. Press <OK> to restore the factory adjustment.

The factory adjustment is restored.
