1-2 Features
High accuracy
The Sine-wave Vibro Viscometer achieves a high measurement accuracy of 1%*
(repeatability) over the full range.
*1 Refer to "14. SPECIFICATIONS" on page 58.
Wide range continuous measurement
Continuous measurement over the whole measuring range is possible, without replacing the
viscosity 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 can
be 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 the
viscosity.
1
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 with
identical 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 of
viscometer as a correction value, the measurement data obtained by the SV series viscometer
can 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-in
function to measure the temperature of the purified water using the temperature sensor and
calculates 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.

4. PRECAUTIONS
To get the optimum performance from the viscometer and acquire accurate measurement data, note
the 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 in
temperature 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, use
an anti-vibration table that is available as an option (AD-1685).
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 hour
or more.
12
4-2 During Use
To level the surface of the sample; adjust the leveling feet so that the center of the narrow part
of the right and left sensor plates is on the liquid surface.
The viscosity of a liquid is temperature dependent and changes by negative 2 to negative 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 the
sensor 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, do not use the accessory sample cup. Use
the glass sample cup (AX-SV-35) that is sold separately or a commercially-available glass
beaker.
The protector can be raised or removed. So, even when a beaker is used, the viscosity can be
measured 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 remove the rotational axis.
Pull the protector in the direction indicated as 2 to
remove.
13
4-3 After Use
Remove any residual sample material from the sensor plates, temperature sensor and
protector using alcohol. Using the sensor plates, temperature sensor and protector with
residue 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 with
tissue 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.

4-4 Measuring the Absolute Value of Viscosity
The SV Series Sine-wave Vibro Viscometer, as a measuring principle, detects the product of viscosity
and 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
(3) Divide the displayed viscosity value by the sample density to obtain the absolute value
of viscosity.
Here, 860 mPa⋅s is obtained as the absolute viscosity value.
Absolute value of viscosity =
as an example.
Displayed viscosity value

15
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 = From this, Density = ⋅ ⋅ ⋅ ⋅ ⋅ [2]
Correction value = Viscosity × Density ⋅ ⋅ ⋅ ⋅ ⋅ [3]
When substituting [2] for the density in [3], the following equation is obtained.
Correction value = ⋅ ⋅ ⋅ ⋅ ⋅ [4]

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 the
temperature when the calibration is performed..
Here, 889 mPa⋅s for the viscosity and 0.878 for the density at 20°C as an example.

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 in
this example. This completes the calibration procedure.

5-1 Preparing the Sample
1 Pour the sample into the cup until its surface
reaches between the level gauges. The level
gauges indicate 35 and 45 mL.
2 Attach the cup on the table along the guides.
3 Confirm that the protector is in the position as
shown in the figure.
Raise the lever to release the sensor unit.
4 Pinch the grips, support the front side of the
sensor unit and gently lower the sensor plates
above the sample surface.
5 Lower the lever to secure the sensor unit.
6 Turn the knob on the table so as
to adjust the sample surface to the
center of the narrow part of the
sensor plates. At this time, use the
surface locator plate as a guide.
The surface locator plate has
been secured in position so that
the tip of the surface locator plate
comes into contact with the
sample surface.
Note
• Be sure to adjust the sample surface to the
center 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 was
removed and attached again, it is
recommended that calibration be

6. 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 for
the 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 the
temperature of the purified water used.
In one-point and two-point calibration, the viscosity of a fluid with a known value, such as a
standard 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 correction value have been entered, the viscometer
condition can be restored. For details, refer to "Initialization (Clr)" of the function setting.
6-1 Notes on Viscosity Calibration
Pay close attention to the liquid temperature at calibration. Be sure to enter the viscosity
value of the liquid temperature at calibration. Even a standard viscosity fluid has a viscosity
change of -2%/°C to -10%/°C, and purified water, a viscosity change of -2%/°C, when the room
temperature changes.
The temperature of the standard viscosity fluid must be the same as the temperature of the
sensor 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 note
that the value, obtained when the viscometer is calibrated without the protector, may be
different from that upon shipment.
If water other than purified water (such as tap water) is used for simplified calibration, or the
water temperature is different from the ambient temperature, bubbles may accumulate on the
sensor 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 and
simplified calibration can not be performed using it. Replace the water.
21
6-2 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 the
displayed value.

Used with the graphing program RsVisco. Measurement data are output in comma separated format.
When a comma is selected as the decimal point by "pnt 1", a semicolon ";" is used as a data separator.
When a measurement is started using RsVisco, the viscometer automatically selects this format.
Measurement data are output in the order of viscosity, viscosity unit, temperature and temperature
unit.
The output data are 25 characters long excluding the terminator
With RsVisco format selected, the viscosity value and the temperature are output using the internal resolution.

12. TROUBLESHOOTING
The viscometer is a precision instrument. When the measuring environment or the measurement
method is inadequate, correct values can not 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 to
vibration.
Avoid these places or use an anti-vibration table, AD-1685.
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 the
temperature 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 when
necessary.
How to remove the protector
Press the left and right side frames lightly in the direction indicated as 1 to remove the
rotational axis. Pull the protector in the direction indicated as 2 to remove.
53
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
shown in 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 so that the tip of the locator
plate aligns to the center 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 of
at least 1 mm between the sensor plate and the surface locator plate. Maintain the
clearance 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 the
temperature sensor. Use much care not to damage them.
54
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 the
sensor 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 will
be 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 the
sample 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 and
the ambient temperature and do the bubbles accumulate on the sensor plates?
The sample viscosity depends on the temperature.
Generally, the viscosity of a liquid is temperature dependent and changes by negative 2
to negative 10 percent, per degree Celsius.
Is the sample surface lowered?
In a measurement that takes a long time, evaporation may cause the sample surface to
be 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.
55
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 to
the measuring environment.
And before measurement, calibrate the viscometer using the sample cup that will be used for
measurement.
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 the
sensor 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 and
the sensor are cooled temporarily and their temperature is lowered. Allow the plates and the
sensor 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 7 to make a connection between the
display 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 the
viscosity 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 water
contamination. Perform a periodic check on water quality.
56
13. ERROR DISPLAY
Error display Description
Above measuring range error
The viscosity value exceeds the upper limit of the viscosity
measuring range (SV-10: 11.99 Pa⋅s, SV-100: 119.9 Pa⋅s).
The viscosity of the sample can not be measured.
This error may occur when the display unit is not connected to
the main unit.
Below measuring range error
The viscosity value is below the lower limit of the viscosity
measuring range (SV-10: 0.30 mPa⋅s, SV-100: 0.90 Pa⋅s)
The viscosity of the sample can not be measured.
This error may occur when the display unit is not connected to
the main unit.
The power supply for the internal clock is depleted.
Press any key to enter the clock correction mode. Setting the
clock enables the viscometer to be used temporarily.
If the error occurs frequently, contact the local A&D dealer for
repair.
Internal IC error
Turn the power off. Then, turn the power on again. If this does
not release the error, contact the local A&D dealer for repair.
