2 Safety Instructions2.2 Warning Symbols on the AMVn Instrument
Warning symbol Hazard on capillary block:
When handling caustic fluids, acids, easily inflammable fluids etc. use therequired protective clothing (protective gloves, safety goggles). If the samples inthe capillary are heated up to measuring temperatures of over 70 C after filling,the thermal expansion of the fluid in the glass capillary may result in theunintentional opening of the capillarys sealing caps.
During the activation of the AMVn instrument, the capillary block moves into thephysical end position (initialization). The capillary block should not be touchedduring this movement, in order to avoid possible clamping or displacement of thezero position. The capillary block should only be moved by hand when theinstrument is inactive.
Warning symbol Hot surface on capillary block:
At measuring temperatures of over 70 C there is risk of burning atvarious parts of the capillary block. Therefore, the capillary block and the usedcapillary should only be touched with adequate safety gloves at thesetemperatures.
Keep in mind that at measurement temperatures of over 70 C the glass capillaryhas the same temperature when extracted, therefore it might cause burns. It isrecommendable to cool down AMVn to temperatures lower than 70 C before thecapillary is touched with bare hands.
Warning symbol on the rear side of AMVn:
Service should only be carried out by qualified personnel. Before service, the mains plug should be disconnected. The instrument needs to be earthed.B80IB01 11
3 AMVn - An Overview3 AMVn - An OverviewAnton Paar GmbH thanks you for buying AMVn, the global vanguard measuringinstrument for the automatic, high-precision viscosity determination of low viscoussubstances. It provides you with measurement solutions of utmost precision in avery broad viscosity and temperature measurement range.
The measurement principle of AMVn is the rolling ball/falling ball principle inaccordance with DIN 53015 and ISO 12058. It consists of the measurement of aballs rolling time in a diagonally mounted glass capillary filled with sample. Theshear rate is influenced by changing the inclination angle of the capillary.In this way, investigations are implemented on whether the measured samplesare Newtonian or non-Newtonian (pseudoplastic or dilatant) fluids.
A built-in Pt100 temperature sensor is used for precise temperaturemeasurements and temperature regulation.
Choose various measurement methods and systems that accord with yourmeasurement applications.
You can print and display measurement results with sample names andmeasurement system data. Only the most recent measurement result is saved inthe AMVn instrument.
In the case of multiple measurement results, it is recommendable to immediatelyprint or note the data. With the optional VisioLab Windows Software, all results can be saved andevaluated in Excel.
The optionally delivered, fully automatic sample changers of Anton Paar GmbHautomatically fill the AMVn capillaries with samples. Between measurements thecapillaries are automatically cleaned with two cleaning agents, and consecutivelydried in air.
Our trained Anton Paar GmbH personnel always welcome your requests and willgladly provide you with additional offers.12 B80IB01

6 Putting AMVn into Operation6 Putting AMVn into OperationAMVn needs to be set up on a stable, level surface. To ensure temperaturestability, never locate AMVn:
next to a heating facility near an air conditioning or ventilation system in direct sunlight.
6.1 Activating AMVn
1. Set up AMVn on the lab desk and level it off with the adjustable feet and thebuilt-in bubble level. Make sure all four feet touch the lab desk.
2. Connect the power inlet of the AMVn instrument to the mains using thedelivered power cord.
3. Activate AMVn with the power switch located on its rear side. The greendisplay light signals that the power is on.
4. After the successful initialization you will see the following reading on thedisplay:
"actual SETTINGS" displays the settings of the last measurement. Browse withF3 or the down button to check the following:
Sample: sample name, remark, temperature, density Method: the last method used Meas. system: the measuring system used for the last measurement Instr. Settings: instrument constant K2, temperature equilibration mode
F4 displays/prints the results of the last measurement.
Caution:Before activating the AMVn instrument make sure that the correct line voltageis applied (85 V to 264 V, 50 Hz to 60 Hz). If large voltage fluctuations are tobe expected, we recommend using a constant-voltage source (UPS).
Warning:After its activation, AMVn independently runs through the coil- and zeroposition initialization. In the course of this the capillary block first moves to itsfinal position before it remains in its home position leaning backwards at20 . The capillary block should not be touched during this movement, in orderto avoid possible clamping or displacement of the zero position. The capillaryblock should only be moved by hand when the power of the instrument isswitched off.

6.2.1 Introducing the Ball to the Capillary
1. Hold the capillary (B) vertically and place the funnel (A) onthe capillary opening (Fig. 6. 1).
2. Use the delivered plastic tweezers to introduce a ball into thefunnel.
Fig. 6. 1 Introduction of the ball
6.2.2 Attaching the Filling Adapter
1. Close the capillary by attaching the filling adapter to it.
Fig. 6. 2 Attaching the filling adapter
2. Check the mobility of the ball by swiveling the capillary.
(B)
Information: Never touch the balls with your fingers, as these need to be completely
clean to function correctly. Only use clean capillaries and clean or new balls.
You can also use an optionally available ball dispenser to introduce the ball.
Caution:Make sure the capillary is completely inserted into the filling adapter. Handlethe capillary with care, it is made of glass and can easily break.20 B80IB01
6 Putting AMVn into Operation6.2.3 Filling the Capillary
1. Introduce a syringe into the cone of the filling adapter.2. Immerse the tip of the capillary in the sample.3. Draw up the sample with the syringe until it is visible in the
lower end of the syringe. The capillary should be completelyfree of air bubbles, otherwise the filling procedure needs to berepeated.
4. Dry the tip of the capillary with a cloth and close it with a LUERcap.
5. Now extract the syringe from the filling adapter and dry theadapter if necessary. Close the filling adapter with the LUERplug.
6. Make sure that the capillarys exterior is clean and dry.7. Again check the mobility of the ball by swiveling the capillary.
Fig. 6. 3 Filling the capillary
6.2.4 Attaching Temperature Tube
Always mount the temperature tube and the protective cap (Chapter 6.2.6) beforeyou start a measurement.
Fig. 6. 4 Attaching the temperature tube and the protection cap
Screw the temperature tube on to the rear side of the capillary block. Forfunctionality reasons it should always stay attached to the capillary block andshould only be unscrewed for cleaning.

6 Putting AMVn into Operation6.2.5 Mounting the Capillary into the AMVn Instrument
Before mounting the filled capillary, you need to activate AMVn and wait until theself-test is concluded (Chapter 6.1).
1. Carefully insert the capillary into the capillary block, starting from the front. 2. Turn the capillary so that the glass knob easily slips into the corresponding
recess of the capillary block opening.
As soon as the glass knob has slid into the opening, completely insert the capillaryinto the capillary block until the red silicone O-ring of the adapter is no longervisible and you meet a resistance.
6.2.6 Attaching Protective Cap
1. After mounting a capillary, attach the protective cap (2, Fig. 6. 4) in a straightposition in the front of the capillary block.
2. Fix the protective cap by turning it clockwise.
Leave the protective cap on the capillary block during the measurement and onlyremove it once you change the capillary.
Caution:Make sure that the self-test is concluded and no measurement program hasstarted, so that the capillary block does not start any surprising movements.Do not push too hard when mounting the capillary, because the glass couldbreak. Do not use excessive force!
Hot surface:When attaching or removing the temperature tube and the protective cap athigh measuring temperatures you might be operating in the direct vicinity ofhot surfaces. Therefore only touch the capillary block and the capillary withadequate protective gloves (Chapter 2.2) or wait until the capillary block hascooled down.
Warning:If the samples in the capillary are heated up to measuring temperatures up to135 C, the thermal expansion of the fluid in the glass capillary may result inthe unintentional opening of the capillarys sealing caps. It is imperative to usethe temperature tube and the protective cap.22 B80IB01

Caution:Choose the angle of your measurement in such a way that the ball rollingtimes do not drop below 10 sec. Otherwise turbulence is caused in thecapillary and a seemingly higher viscosity is read. In this case choose another measuring method (Chapter 8.2.1).
Information:Always enter an even number of repetitions, because viscosity is alwaysdetermined from two repetitions.For the viscosity calculation a maximum of 20 repetition periods is used. If youwant more than 20 repetitions, you have the further option of connectingAMVn to a PC. The AMVn Visiolab Windows software allows a nearlyunlimited amount of repetitions, which is only one of its many benefits.

9 Calibration of Measuring Systems9 Calibration of Measuring SystemsFor a precise viscosity determination, the calibration of the capillary is necessary.The calibration constant is different at every angle and with every capillary.
9.1 Calibrated and Uncalibrated Capillaries
There are calibrated and uncalibrated measuring system sets (Chapter 4.2.2) andcalibrated and uncalibrated capillaries:
Calibrated capillary: calibrated at certain angles and a certain temperaturebefore delivery. The data is stored on a data medium and on the calibrationcertificate. Both is delivered. Manually enter the calibration constant datastated on the calibration certificate in the firmware, menu "SetupMeasurement" (also see Chapter 8.2). Import the calibration constant fromthe data medium in the Visiolab software.
Uncalibrated capillary: determine the calibration constant acc. tocalibration procedure and store this value in the menu "SetupMeasurement" (Chapter 8.2).
When using a new or alternative ball set the calibration constant only needs tobe redefined in case the measuring deviation is above tolerance limit (0.3 %) and/or the ball set features a different batch number. Read the batch number on thesticker attached to your ball set.
When calibrating a measuring system, choose the viscosity standard in such away that it falls within the viscosity range of the measurement at the usualmeasuring temperature (Chapter A.1).

10 Maintenance10 MaintenanceClean AMVn and its accessories regularly.
We recommend regular maintenance of your measuring instrument by authorizedAnton Paar GmbH personnel.
10.1 Cleaning the Measuring System
A thorough cleaning of the AMVn measuring system after each measurement ormeasurement series is imperative.
1. Remove the protective cap and clean it if necessary.2. Remove the capillary from the the capillary block. Take care not to twist the
capillary.3. Remove the LUER plug and insert a syringe into the filling adapter.4. Now remove the LUER cap and rinse the capillary with cleaning agent.
Repeat the rinsing procedure several times by flushing out and drawing upthe cleaning agent.
5. After the cleaning procedure remove the syringe and the filling adapter.6. Use a volatile solvent, e.g. highly concentrated alcohol or acetone, to
accelerate the drying procedure after cleaning.7. Dry the measuring system e.g. with compressed air (max. 0.5 bar).8. Check that the ball moves easily when the capillary is swiveled. This
concludes the cleaning procedure.
10.2 Cleaning the Filling Adapter
Clean the filling adapter regularly to avoid clotting or the ball getting stuck.
1. Detach the filling adapter from the capillary with gentle turns. Do not useexcessive force as this could break the capillary.
2. Rinse the filling adapter with a cleaning agent.3. Rinse the filling adapter with a volatile solvent, e.g. highly concentrated
alcohol, to accelerate the drying procedure after cleaning.4. Afterwards dry the filling adapter, e.g. with compressed air (max. 0.5 bar).
Caution: Do not leave any samples in the measuring system after finishing the
measurement. Rinse the measuring system with a suitable cleaning agent. Only use cleaning agents that are compatible with the materials (Chapter
10.4). Before you dry the capillary with compressed air, remove the ball.38 B80IB01
10 Maintenance10.3 Cleaning AMVn
Use a soft cloth and warm water to clean the casing and display.
Dry the AMVn instrument with a soft, dry cloth.
Wash the drip plate regularly with a suitable cleaning agent.
Regularly unscrew the thermostat and rinse it with cleaning agent.
Check the capillary block for pollution and clean it regularly, especially at thethermostat and protective cap fixations.
Never remove the warning signs on the capillary block. If these come loose,they need to be attached again.

Appendix A: ViscosityAppendix A: ViscosityFor a precise viscosity determination, a suitable calibration standard fluid isrequired for the calibration of the capillaries. A calibration constant needs to bedetermined and/or entered for every capillary (Chapter 9).
A.1 Viscosity Standard Fluids
Due to the different measuring ranges of the capillaries, you need differentviscosity standard fluids. You can order these viscosity standard fluids at AntonPaar GmbH.
The table below shows general values for the different measuring systems.
The best results are achieved if you calibrate a measuring system at the usualmeasuring temperature and in its viscosity range. (e.g. if you measure approx. 50 mPa.s with a 3.0 measuring system at 100 C,use e.g. the viscosity standard fluid DKD 10000. At 100 C this standard hasapprox. 57 mPa.s).
For measuring aqueous samples we recommend bidistilled water as a viscositystandard fluid.
* for extended measuring range
Choose the appropriate temperature (according to the calibration certificate) toreach the recommended viscosity for calibration.
A custom-tailored calibration is possible. You can use any stable sample withknown dynamic viscosity and density as a viscosity standard fluid.
Information:The calibration procedure has to be repeated periodically, depending on thespecific accuracy requirements of your laboratory.

Appendix A: ViscosityA.2 Calibration Constant K1
For every measuring angle you plan to use, first determine the calibrationconstant K1.

A.3 Determining the Viscosity
The dynamic viscosity of the sample is calculated from the calibration constantK1 of the measuring system, the rolling time t1 and the density difference between ball and sample.
= K1 * (K - P) * t1
... dynamic viscosity of sample [mPa.s]K1 ... calibration constant of the measuring system [mPa.cm3/g]K ... ball density [ g/cm3] (steel ball = 7.85 g/cm3)P ... density of the measured sample [ g/cm3]t1 ... ball rolling time [s]
The serial number and the ball density of the measuring system are known (steelball: K = 7.85 g/cm3, tungsten carbide-cobalt ball: K = 15 g/cm3). The density ofthe sample, often a known number, must also be entered. If there is no information on the density of the sample to be measured, you canorder a manual density meter DMA 35N from Anton Paar GmbH, which measuresthe density with an accuracy of +/- 0.001 g/cm3.
K1
Nt1
K( N )
-----------------------------------=
Information: The calibration constant is different at every angle and with every
capillary. A calibration datasheet with pre-determined calibration constants for the
stated angles is enclosed with every calibrated capillary. If a ball is exchanged, K1 only needs to be readjusted if the measuring
deviation is above the tolerance limit (0.3 %). Readjust the constant if you use balls with different batch numbers. The batch number is written on the ball vessel.
The viscosity of the standard fluid should fall within the viscosity range of the measured samples.
Caution:Choose the angle of your measurement in such a way that the ball rollingtimes do not drop below 10 sec. Otherwise turbulence is caused in thecapillary and a seemingly higher viscosity is read.43 B80IB01
Appendix B: Extension of the Measuring RangeAppendix B: Extension of the Measuring Range
B.1 Quadrupling the Maximum Measuring Range
A measuring range extension through an increase in run time from 250 to 999 secquadruples the maximum measuring range.
The run time increase can only be defined by means of a "remote" command fromthe PC.
Proceed as follows:
1. Connect AMVn and PC with the interface cable. 2. Switch on your AMVn and the PC.3. Start the Windows Terminal Program
PC port: 9600, 8 databit, no parity, 1 stop bit, no handshake.4. The following commands, which need to be typed using capital and small
letters, define the max. runtime to 999 sec:
Appendix B: Extension of the Measuring RangeB.2 Doubling the Maximum Measuring Range
A measuring range extension through the use of tungsten carbide-cobalt ballsdoubles the maximum measuring range, as they have approx. twice the density(15 g/cm) and therefore half the runtime.
Before calibrating the measuring system 4.0 with tungsten carbide-cobalt balls,read Chapter 9 and proceed accordingly.
Proceed as follows:
1. Select capillary 4.0 mm.2. Insert 3 mm tungsten carbide-cobalt balls.3. Fill the capillary with viscosity standard fluid and start the calibration.
