1. INTRODUCTION
This manual describes how the SV series viscometer works and how to get the most out of it interms of performance.
Read this manual thoroughly before using the viscometer and keep it at hand for future reference.

1-1 Compliance
Compliance with FCC Rules
Please note that this equipment generates, uses and can radiate radio frequency energy. Thisequipment has been tested and has been found to comply with the limits of Class A digital
devices pursuant to Part 15 of FCC rules. These rules are designed to provide reasonable
protection against interference when equipment is operated in a commercial environment. If
this unit is operated in a residential area, it may cause some interference and under thesecircumstances the user would be required to take, at his own expense, whatever measures
are necessary to eliminate the interference. (FCC = Federal Communications Commission in
the U.S.A.)6

1-2 Features
 High accuracy
The Sine-wave Vibro Viscometer achieves a high measurement accuracy of 1%*1
(repeatability) over the full range.
*1 Refer to "15. SPECIFICATIONS" on page 61.
 Wide range continuous measurement
Continuous measurement over the whole measuring range is possible, without replacing theviscosity detection sensor plates.
 Standard temperature sensor
The temperature sensor to measure the sample temperature is installed as standard. The
temperature sensor is located between the two sensor plates. So, the accurate detection of
the relation between temperature and viscosity is possible.
 Accurate measurement
Due to the low heat capacity of the viscosity detection unit (sensor plates and temperature
sensor), the time required for temperature equilibrium is short. Thus, the sample viscosity canbe measured accurately in a short time.
 Long continuous measurement time
The sensor plates, with a low frequency of 30 Hz and an amplitude of less than 1 mm, apply
very little load to the sample. So, the viscometer can continuously obtain stable viscosity
values without causing a temperature rise or damaging the sample.
 Measurement of a non-Newtonian fluid/foaming sample
The thin sensor plates allow little deformation of the sample texture. Thus, non-Newtonian fluid
can be measured in a stable way. And, foaming samples can be measured without breaking
minute foam particles and with less influence scattering large foam particles.
When measuring tap water, bubbles may accumulate on the sensor plates, increasing theviscosity.
 Measurement of a flowing sample
The two sensor plates oscillate in the opposite direction. So, even when a sample is in motion,
errors are eliminated. This allows measurement of a sample while being stirred. The
viscometer can be used for a flowing product line, which enables field management withidentical data used at the laboratories.
 Calibration
The viscometer can be calibrated using a standard viscosity fluid or a sample of a known
viscosity. Calibration allows the viscometer to maintain the accuracy constantly.
By calibrating an actual sample, using the viscosity value obtained by another type ofviscometer as a correction value, the measurement data obtained by the SV series viscometercan be combined into those obtained by the other type of viscometer.
 Simplified calibration when measuring the viscosity near 1 mPa⋅s, (SV-10 only)
Simplified calibration using purified water is a one-key operation. The SV-10 has a built-infunction to measure the temperature of the purified water using the temperature sensor andcalculates the viscosity value of the purified water at that temperature.
At this time, be careful not to influence the viscosity value by generating bubbles.
 Standard windows communication tools WinCT-Viscosity
Windows communication tools WinCT-Viscosity (CD-ROM) is provided as standard. The
CD-ROM contains the graphing program RsVisco, which imports the data to a personal
computer and displays the results as a graph in real time. With RsVisco, changes in viscosity
over time and temperature dependency of viscosity can be observed easily and the obtained
data can be saved in files.

72. UNPACKING THE VISCOMETER

material to be used for transporting the viscometer in the future.

4. PRECAUTIONS
To get the optimum performance from the viscometer and acquire accurate measurement data, notethe following:

4-1 General Precautions
 Install the viscometer in an environment where the temperature and humidity are not excessive.
The best operating temperature is 25°C±2°C at 45-60% relative humidity.
 For precise measurement, install the viscometer where there are no great changes intemperature and humidity.
 Install the viscometer where it is not exposed to direct sunlight and it is not affected by heaters
or air conditioners.
 Install the viscometer where it is free of dust.
 Install the viscometer away from equipment which produces magnetic fields.
 The viscometer uses the Tuning-fork Vibration Method. So, use much care to avoid external
vibration, especially when measuring low viscosity.
Places where the viscometer is prone to vibration are:Second or higher floor, soft ground, near busy highways or rail lines.
Avoid these places as a measuring site. If measurement is to be performed in such a place, usean anti-vibration table that is available as an option (AD-1671A).
 Protect the internal parts from liquid spills and excessive dust.
 Do not disassemble the viscometer.
 When precise measurement is required, acclimatize the viscometer to the measuring
environment. After installation, plug in the AC adapter and warm up the viscometer for one houror more.

15

4-2 During Use
 To level the surface of the sample; adjust the leveling feet so that the center of the narrow partof the right and left sensor plates is on the liquid surface.
 The viscosity of a liquid is temperature dependent and changes in accordance with thetemperature change. In general, if the temperature rises, the viscosity value decreases about 2
to 10 percent per degree Celsius. Take changes in the liquid temperature into consideration for
an accurate measurement.
 Be sure to calibrate using the standard viscosity fluid or purified water before measurement.
In a measurement that takes a long time, perform calibration periodically, as necessary.
 Placing the sensor plates and the temperature sensor in the sample may change the sample
temperature. For precise measurement, leave the sample as is for a while, after placing thesensor plates and the temperature sensor, to ensure no changes to the sample temperature.
And then, start a measurement.
 Ensure a stable power source when using the AC adapter.
 Use only your finger to press the keys. Using a sharp instrument such as a pen may damage
keys.
 The sample cup is made of polycarbonate (PC) and is not appropriate for organic solvents.
When organic solvents are used as a sample fluid, use the glass sample cup (AX-SV-35) that issold separately or a commercially available glass beaker.
 The protector can be raised or removed. So, even when a beaker is used, the viscosity can bemeasured with a small amount of sample.
How to remove the protector:
Press the left and right side frames lightly in the
direction indicated as 1 to release the rotational axes.
Pull the protector in the direction indicated as 2 toremove.

16

4-3 After Use Remove any residual sample material from the sensor plates, temperature sensor andprotector using alcohol. Using the sensor plates, temperature sensor and protector withresidue of an old sample left on will cause a measurement error.
Clean the sensor plates carefully to avoid bending them.
The sensor plates and the temperature sensor are made of stainless steel (SUS304). The
surface is plated with 24K gold.
Note
Liquids with strong acidity may remove the gold plating and corrode the sensor plates
and the temperature sensor.

How to clean the sensor plates and temperature sensor
Hold the sensor plate or temperature sensor withtissue paper. Move the tissue paper downward to
remove the sample.
Then, use tissue paper moistened with alcohol,
to remove any residual sample material.

 Clean the sample cup as necessary.

 Unlock the cable connector before disconnecting the connection cable.
How to unlock the cable connector174-4 Measuring the Absolute Value of Viscosity
The SV Series Sine-wave Vibro Viscometer, as a measuring principle, detects the product of viscosityand density.
Displayed viscosity value = Viscosity × Density ⋅ ⋅ ⋅ ⋅ ⋅ [1]While the displayed value has a unit of mPa⋅s, it indicates the product of viscosity and density.

Example (1) When a sample has an absolute value of viscosity of 2.00 mPa⋅s and density of 1.000:
Displayed value = 2.00 [mPa⋅s] × 1.000= 2.00 [mPa⋅s](2) When a sample has an absolute value of viscosity of 2.00 mPa⋅s and density of 0.800:
Displayed value = 2.00 [mPa⋅s] × 0.800= 1.60 [mPa⋅s]
Note
The density can be measured, using the density determination kit, AD-1653 in
combination with a balance.
To obtain the absolute viscosity value precisely, do as follows:

4-4-1 At Measurement
Divide the displayed viscosity value by the sample density to obtain the absolute value of viscosity.
Example (1) Measure the sample and confirm the displayed viscosity value.
Here, 736 mPa⋅s as an example.
(2) Check the sample density at the temperature when the sample is measured.
Here, 0.856 as an example.
(3) Divide the displayed viscosity value by the sample density to obtain the absolute valueof viscosity.
Here, 860 mPa⋅s is obtained as the absolute viscosity value.
Absolute value of viscosity ==Displayed viscosity value
Sample density
736
0.856

18

≅ 860 mPa⋅s

4-4-2 At Calibration
When calibrating, enter the product of the absolute viscosity value and the density of the standard
viscosity fluid used for calibration, as a correction value.
The standard viscosity fluid has the calculation sheet of kinetic viscosity and viscosity at various
temperatures attached. To obtain the correction value using this sheet, do as follows:
Kinetic viscosity =Viscosity
Density

From this, Density =Viscosity
Kinetic viscosity⋅ ⋅ ⋅ ⋅ ⋅ [2]Correction value = Viscosity × Density ⋅ ⋅ ⋅ ⋅ ⋅ [3]When substituting [2] for the density in [3], the following equation is obtained.
Correction value =Viscosity2
Kinetic viscosity⋅ ⋅ ⋅ ⋅ ⋅ [4]Example 1: To calibrate the viscometer using a standard viscosity fluid:
Using the calculation sheet, calculate the value used for calibration.
(1) Check the kinetic viscosity and the viscosity at the temperature when the calibration is
performed.
Here, 1011 mm2/s for the kinetic viscosity and 889 mPa⋅s for the viscosity at 20°C
as an example.
(2) Substitute the values above into equation [4].
8892
1011

≅781

781 mPa⋅s is obtained as a correction value used for calibration.
(3) After calibration, measure the viscosity of the standard viscosity fluid used and confirm
that the viscometer displays the similar value as the correction value, 781 mPa⋅s inthis example. This completes the calibration procedure.
Example 2: To calibrate using a standard viscosity fluid with known values of viscosity and density.
In this example, a standard viscosity fluid with a viscosity of 889 mPa⋅s at 20°C is used.
(1) Check the viscosity value and the density of the standard viscosity fluid at thetemperature when the calibration is performed..
Here, 889 mPa⋅s for the viscosity and 0.878 for the density at 20°C as an example.
(2) Substitute the values above into equation [3].
889 × 0.878 ≅ 781
781 mPa⋅s is obtained as a correction value used for calibration.
(3) After calibration, measure the viscosity of the standard viscosity fluid used and confirm
that the viscometer displays the similar value as the correction value, 781 mPa⋅s inthis example. This completes the calibration procedure.

Raise the lever to release the sensor unit.

4 Pinch the grips, support the front side of thesensor unit and gently lower the sensor plates
above the sample surface.

5 Lower the lever to secure the sensor unit.

20

6 Turn the knob on the table so as
to adjust the sample surface to thecenter of the narrow part of thesensor plates. At this time, use thesurface locator plate as a guide.
The surface locator plate has
been secured in position so thatthe tip of the surface locator platecomes into contact with thesample surface.

SV-10

Note
• Be sure to adjust the sample surface to thecenter of the narrow part of the sensor plates.
Otherwise, a measurement error may occur.
• The surface locator plate can be attached or
removed by loosening the screw.
• Before removing the sensor protective
cover, remove the surface locator plate.
• When the surface locator plate is removed
and attached again, it is recommended
that calibration be performed using thestandard
viscosity
fluid
beforemeasurement.

SV-100Note
Use the protector in the position as shown on the left below. If the protector is not used with
the SV-10, a measurement error may occur, especially in measuring a viscosity over 5000mPa⋅s.

NO

6. USING THE DISPOSABLE CUP
6-1 Introduction
The disposable cup is a cup with a capacity of 10 mL to be used in combination with a sample cup(capacity: 35 mL to 45 mL) or the water jacket. It can be disposed of after use.
The operating temperature range is 0°C to 80°C.

6-2 How to use
6-2-1 Using with a sample cup (Capacity: 35 mL to 45 mL)
Place the disposable cup into the sample cup.

Disposable cup(Capacity: 10 mL)

Sample cup

Pour the sample into the disposable cup up to the 10 mL line and measure the viscosity.

6-2-2 Using with the water jacket
Place the disposable cup into the water jacket. Secure the cup to the water jacket using the screw
provided with the water jacket. (Refer to page 66 for the AX-SV-37 water jacket.) When used with the water jacket, in combination with a constant temperature bath for circulating theheating medium, the viscosity can be measured while changing the sample temperature or
maintaining it constant.

Water jacket

Pour the sample into the disposable cup up to the 10 mL line and measure the viscosity.

6-3 Measuring the Absolute Value of Viscosity Using the Disposable Cup
The SV-10A/100A has been calibrated using the accessory sample cup (45 mL) when shipped. The
distance between the inner wall and the sensor plates when the accessory sample cup is used,differs from the distance when the disposable cup is used. This causes a difference in the sensor
plate's detection capability, thus causing a difference in the viscosity measured.
Therefore, to measure the absolute value of viscosity using the disposable cup, it is recommended thatcalibration be performed using a fluid with a known viscosity value which is close to the sample
viscosity. (Refer to "7. VISCOSITY CALIBRATION".)

7. VISCOSITY CALIBRATION
 Viscosity calibration is to correct the viscosity value.
 Two calibration methods are available: one-point calibration and two-point calibration, using
standard viscosity fluids.
With the SV-10, simplified calibration using purified water is available.
 It is recommended that calibration be performed using a fluid with a known viscosity value
which is close to the sample viscosity.
When the measuring range is great, perform two-point calibration. Two-point calibration
requires two standard viscosity fluids (high viscosity and low viscosity) that are appropriate forthe measuring range.
 With the SV-10, when measuring the viscosity near 1 mPa⋅s, simplified calibration using
purified water, which is a one-key operation, is available. The SV-10 has a built-in function to
perform an automatic temperature compensation on the viscosity value, based on thetemperature of the purified water used.
 In one-point and two-point calibration, the viscosity of a fluid with a known value, such as astandard viscosity fluid, is measured, displayed, corrected digitally and saved in memory.
 To obtain the absolute viscosity value precisely, use the correction value as described in"4-4-2 At Calibration".
 If the wrong calibration data such as a wrong correction value have been entered, theviscometer condition can be restored to the factory setting. For details, refer to "Initialization(Clr)" of the function setting.

7-1 Notes on Viscosity Calibration
 Pay close attention to the liquid temperature at calibration. Be sure to enter the temperaturecorrected viscosity value of the liquid at calibration. Even when using a standard viscosity fluid, thetemperature change near room temperature causes viscosity change. If the temperature rises, theviscosity value decreases about 2 to 10 percent per degree Celsius. And even when using purified
water, temperature rise causes viscosity decrease of about 2 percent per degree Celsius.
 The temperature of the standard viscosity fluid must be the same as the temperature of thesensor plates and the temperature sensor. Allow the displayed temperature to stabilize before
calibration.
 Be sure to adjust the sample surface to the center of the narrow part of the sensor plates.
Otherwise, a measurement error may occur.
 In the calibration mode, the unit of viscosity for the SV-10 is mPa⋅s, for the SV-100, Pa⋅s.
The unit of temperature is fixed to °C.
 The viscometer has been calibrated with the protector attached when shipped. Please notethat the value, obtained when the viscometer is calibrated without the protector, may bedifferent from that upon shipment.
 If water other than purified water (such as tap water) is used for simplified calibration, or thewater temperature is different from the ambient temperature, bubbles may accumulate on thesensor plates and cause a measurement error. Allow the sample to adjust to the ambient
temperature and remove any accumulated bubbles before calibration.
 If the measured viscosity of the water is 3.00 mPa⋅s or greater, it is contaminated andsimplified calibration cannot be performed using it. Replace the water.

26

7-2 Calibration Procedure
Note
As to the correction value used for one-point calibration and two-point calibration, enter the
product of the absolute viscosity value and the density of the standard viscosity fluid. For
details, refer to "4-4-2 At Calibration".
After calibration, check the values, comparing the product described above with thedisplayed value.
Kinetic viscosity =Viscosity

From this, Viscosity × Density =Density

is obtained.

Example 1: To calibrate the viscometer using a standard viscosity fluid:
Using the calculation sheet, calculate the value used for calibration.
(1) Check the kinetic viscosity and the viscosity at the temperature when the calibration is
performed.
Here, 1011 mm2/s for the kinetic viscosity and 889 mPa⋅s for the viscosity at 20°C
as an example.

(2) Substitute the values above to obtain the value for

≅781

781 mPa⋅s is obtained as a correction value used for calibration.
Example 2: To calibrate using a standard viscosity fluid with known values of viscosity and density.
In this example, a standard viscosity fluid with a viscosity of 889 mPa⋅s at 20°C is
used.
(1) Check the viscosity value and the density of the standard viscosity fluid at thetemperature when the calibration is performed..
Here, 889 mPa⋅s for the viscosity and 0.878 for the density at 20°C as an example.
(2) Substitute the values above to obtain the value for Viscosity × Density.
889 × 0.878 ≅ 781
781 mPa⋅s is obtained as a correction value used for calibration.

9. CONNECTION TO A PERSONAL COMPUTER
Using the standard RS-232C serial interface and the RS-232C cable provided, the viscometer canbe connected to a personal computer.
In addition, using the graphing program RsVisco, contained in the accessory Windows
communication tools WinCT-Viscosity, measurement data are imported to a Windows-based
personal computer to display a graph in real time.
For details, refer to "\English\ReadMe.txt" on the CR-ROM.

10. CONNECTION TO A PRINTER The viscometer can be connected to the optional compact printer, AD-8121B using thestandard RS-232C serial interface and the measurement results can be printed.
 The statistical calculation data of the results and the changes in the viscosity value per acertain time can be printed using the function of the AD-8121B.
 Use the AD-8121B accessory cable to connect the printer to the viscometer.

13. TROUBLESHOOTINGThe viscometer is a precision instrument. When the measuring environment or the measurement
method is inadequate, correct values cannot be obtained. If measurement values do not become
stable or they seem to be incorrect, check as described below. If improper performance persists after
checking, contact the local A&D dealer for repair.

When measurement values do not become stable: Is the ambient environment free from vibration and drafts?
 Places such as second or higher floor or near busy highways or rail lines are prone tovibration.
Avoid these places or use an anti-vibration table, AD-1671A.
 Reconsider the setting of "Condition (Cond) ” of the function setting.
Set it to "Cond 2".
 Avoid direct drafts in the vicinity of the viscometer.
 Is there a strong electrical or magnetic noise source such as a motor near the viscometer?
 Install the viscometer away from the electrical or magnetic noise sources.
 Is the protector or the sensor protective cover in contact with the sensor plates or thetemperature sensor?
 Attach the protector and the sensor protective cover properly so that they do not touch
the sensor plates or the temperature sensor.
 Remove the protector, the surface locator plate or the sensor protective cover whennecessary.
How to remove the protector

Press the left and right side frames lightly in the direction indicated as 1 to release therotational axes. Pull the protector in the direction indicated as 2 to remove.

How to remove and attach the surface locator plate
Removing
Loosen the screw and remove the surface
locator plate from the temperature sensor.

Attaching
Install the surface locator plate as shownin the illustration. Slip the locator plate onto
the temperature sensor. Move the plate to
the top of the sensor.
Adjust the position of the locator plate sothat the tip of the locator plate aligns to thecenter of the narrow part of the sensor
plates.
Tighten the screw.
Note
When the sensor plate and the surface locator plate are too close, a measurement
error may occur due to the liquid surface tension. Therefore, secure a clearance ofat least 1 mm between the sensor plate and the surface locator plate. Maintain theclearance by rotating the surface locator plate when necessary.

How to remove the sensor protective cover(Sensor unit side view)
Remove the protector and the surface locator plate.
Pull the sensor protective cover in the direction indicated as 1 to release the portions A(two) and B from the protector frame.
Pull the sensor protective cover in the direction indicated as 2 to remove.
Note
When removing the sensor protective cover, it may touch the sensor plates and thetemperature sensor. Use much care not to damage them.

57

When measurement values are not correct:
 Has the sample surface been adjusted to the center of the narrow part of the sensor plates?
 Adjust the table height by turning the knob so that the center of the narrow part of thesensor plates is on the sample surface.
 Are the positions of the left and right sensor plates in the sample surface the same?
 If not the same, level the viscometer using the leveling feet so that the liquid surface willbe leveled.
 Are the sensor plates clean?
 Remove any residual sample material from the sensor plates using alcohol.
 When any residual sample material is on the portion of the sensor plates above thesample surface, changes in the mass cause the vibration frequency to shift, which will
result in a measurement error.
 Are the sensor plates bent?
 If bent, contact the local A&D dealer for repair.
 Does the sample generate bubbles because of the differences in the sample temperature andthe ambient temperature and do the bubbles accumulate on the sensor plates?
 The sample viscosity depends on the temperature.
 In general, because the viscosity of a liquid depends on its temperature, the viscosity
value decreases about 2 to 10 percent per degree Celsius if increasing the temperature.
 Is the sample surface lowered?
 In a measurement that takes a long time, evaporation may cause the sample surface tobe lowered. Maintain the sample surface level.
 Do the main unit and the display unit have the same serial number?
 The main unit and the display unit have been adjusted in pairs. Confirm that the main
unit and the display unit have the same serial number.
 Is the viscometer in the data hold mode?
 To release the data hold mode,press the HOLD key.
 The processing indicator blinks
while a measurement is performed.
 Is calibration performed?
 When the absolute viscosity value is important, it is recommend that a periodic
calibration be performed using a standard viscosity fluid.

58

When more precise measurement is required: When the viscometer is installed for the first time or is moved to another location, plug in the
AC adapter and warm up the viscometer for one hour or more, to acclimatize the viscometer tothe measuring environment.
And before measurement, calibrate the viscometer using the sample cup that will be used formeasurement.
 Placing the sensor plates and the temperature sensor in the sample may change the sample
temperature. For precise measurement, leave the sample as is for a while, after placing thesensor plates and the temperature sensor, to ensure no changes to the sample temperature.
And then, start a measurement.
 When the sensor plates and the temperature sensor are cleaned using alcohol, the plates andthe sensor are cooled temporarily and their temperature is lowered. Allow the plates and thesensor to acclimatize to the measuring environment before measurement.

When the temperature values are not correct:
 Is the display unit connected to the main unit properly using the connection cable?
 Refer to "2-2 Installing the Viscometer" on page 9 to make a connection between thedisplay unit and the main unit.

When water viscosity is to be measured: When tap water is poured into the sample cup directly and is measured, bubbles are
generated on the sensor plates due to the difference in pressure and temperature and theviscosity may increase gradually. Pressurized tap water generates bubbles easily. Therefore,
use distilled or purified water that is not pressurized.

 In a measurement that takes a long time, the sample viscosity may increase due to watercontamination. Perform a periodic check on water quality.
