Switching on the device
Introduction
After switching on the viscometer, the information screen is dis-
played for 4-5 seconds, showing the device name, software versi-
on and series of the viscometer.
To cover a wide range of viscosity, 4 different types of devices are
available.
Depending on the used measurment spindle and the selected
speed, the viscosity range of the specific type varies, which you
may find it via: Menu -> Viscosity -> Spindle -> Search
lo-vi = low viscosity
me-vi = medium viscosity
hi-vi I = high viscosity I
hi-vi II = high viscosity II
Firmware update screen
The “Firmware update screen“ screen will be shown for 5 seconds.
Device self checking
• Remove the spindle Press the knob
During this period, the spindle icon will move from the top to
the bottom.
Note: Remove the protection cap from the device.
Remove the spindle from the device.
• Device self checking...
During this period, the spindle icon will rotate.
There are two moving lines:
• The red angular line pivoting around the center of the circle,
represents the rotation of the device around the X-axis. When
the line is horizontal (matching the white line), the device will be
in balance with the X-axis, and then the line color will turn from
red to green.
• The small horizontal white line inside the circle, is moving ver-
tically and it represents the rotation around the Y-axis. When it
matches the white line, the device will be in balance with the
Y-axis, then the line color will turn from white to green.
The three buttons represent the three stand levelers. The arrows
show in which direction they have to be adjusted (green = up;
red = down).
The adjustment steps are as follows:
• It is recommended that you adjust the X-axis first and the Y-axis
afterwards.
• After successfully aligning the X-axis, you can adjust the Y-axis.
If the X-axis gets out of balance while adjusting the Y-axis, go
back to the previous step.
• As soon as the small horizontal red line inside the circle matches
the center line, all the lines will turn green.
Always two possibilities of knob adjusting are shown, because the
knob position could be already at the limit.
When X-axis and Y-axis are both centered, the device is leveled.
Press the knob to confirm OK.
Check that the power supply matches the data on the rating plate.
Plug the AC adapter into a standard mains socket in order to sup-
ply the device with power.
Level meter
Observe the connection values and the ambient conditions (tem-
perature, humidity, etc.) listed under “Technical data”.
Once these conditions are satisfied, and the mains plug has been
plugged in, the device is ready to operate.
Note: Firmware update screen can be modified by:
Menu -> Settings -> Display -> Firmware update screen
• Device self checking is done. After this step, the screen will
switch to the main screen.
Note: Device self checking will take approx. 30 seconds.

Sample container size
For measurements with standard viscometer models we recommend
a container with an inside diameter of no less than 83 mm. The usual
vessel for this purpose is a 600 ml Grin beaker. Using a smaller con-
tainer will result in an increase in viscosity readings.
Guard rail
IKA provides an lo-vi guard rail for lo-vi device and an me-vi guard rail
for me-vi/hi-vi I/hi-vi II devices.
The spindle guard rail protects the spindle from damage and provide
a higher accurancy.
Effect on accuracy when using accessory devices
The IKA Rotavisc has a stated accuracy of ±1 % of the full scale range
in use. This stated accuracy applies when the viscometer is used in
accordance with the operating instructions and the calibration test
fluid is used in accordance with the instructions provided by the fluid
supplier (including the critical parameters of temperature control and
stated fluid accuracy). IKA’s accuracy statement of ±1 % of the ran-
ge in use applies to the IKA Rotavisc when used with the standard
spindles supplied with the device in a 600 ml Grin beaker.
IKA offers a range of accessories for use with the IKA Rotavisc to ac-
commodate special measurement circumstances. These accessories,
while offering added capability to you, also contribute to an expan-
ded measurement tolerance beyond the device accuracy of ±1 % of
the range in use. This expanded measurement tolerance is a function
of many parameters including spindle geometry, accessory alignment
accuracy, sample volume requirement, and sample introduction tech-
niques. The effect of these elements on measurement tolerance must
be considered when verifying the calibration of your IKA Rotavisc.
Sample temperature in all test circumstances is very important, and
will also add an additional expanded tolerance depending on the
temperature control system and the calibration verification tests be-
gin with the standard viscometer spindles as detailed above.
Viscosity calibration fluids often show an accuracy of ±1% of the no-
minal volume!
Notes
• The viscosity is shown in units of centipoise (shown as “cP”) or
milliPascal-seconds (shown as“mPa•s“).
• The shear stress is shown in units of dynes/square centimeter (“D/
cm2”) or Newton/square meter (“N/m2”).
• The shear rate is shown in units of reciprocal seconds (“1/s”).
• The torque is shown in units of dyne-centimeters or Newton-me-
ters.
• The torque percentage is shown as “xx.x %”.
The equivalent units of measurement in the CGS system are calcula-
ted using the following conversions:
SI CGS
Viscosity: 1 mPa•s = 1 cP
Shear stress: 1 Newton/m2= 10 Dyne/cm2
Torque: 1 Newton-m = 107dyne-cm
References to viscosity throughout this manual are done in SI units.
The IKA Rotavisc provides equivalent information in CGS units.
Base for reliable viscosity measurements is laminar flow! If the mea-
surement spindle turns too fast, turbulence occurs. The result is not
valid.
Always consider a shown torque >10% and less 90%. Smaller and
bigger values will also show non valid viscosity values too.

Useful information
Measurement principle
The measuring principle of IKA Rotavisc is to use the stepping mo-
tor to drive a measuring spindle (which is immersed in the test fluid)
through a linearity calibrated spring sensor. The viscous resistance of
the fluid against the spindle is detected by the spring deflection. The
spring deflection is measured with a rotary transducer. The measure-
ment range of IKA Rotavisc is determined by the spring, the spindle
and the speed. Please refer to Appendix B for “Range coefficient”.
There are four basic spring torque series offered by IKA:
The device measurement range depends on the calibrated torque,
the higher torque means the wider range. All units of measurement
are displayed to either the CGS system or the SI system, which you
can choose via the menu.

Use the USB interface in conjunction with labworldsoft®for op-
eration in “Remote” mode and also to update the firmware.
USB device drivers
First, download the latest driver for IKA devices with USB inter-
face from:
http://www.ika.com/ika/lws/download/usb-driver.zip.
Install the driver by running the setup file. Connect the IKA device
through the USB data cable to the PC. The data communication
runs through a virtual COM port.
Configuration, command syntax and commands of the virtual
COM ports are as described in RS 232 interface.
Serial RS 232 interface
Configuration
• The functions of the interface circuit between the laboratory
device and the automation system are a selection from the
signals specified in the EIA standard RS 232 as per DIN 66020
Part 1.
• Standard RS 232, corresponding to DIN 66259 Part 1 is valid
for the electronic characteristics of the interface circuits and
assignment of signal states.
• Transmission process: asynchronous character transmission in
start-stop operation.
• Transmission type: full duplex
• Character format: character composition according to data
format in DIN 66022 for start-stop operation. 1 start bit,
7character bits, 1 parity bit (even), 1 stop bit.
• Transmission speed: 9,600bit/s
• Data flow control: none
• Access method: data transmission from the device to the
computer only occurs after a request from the computer.
Command syntax and format
The following points should be noted for the instruction set:
• Commands are generally sent from the computer (master) to
the lab device (slave).
• The lab device only responds to requests from the computer.
• Commands and parameters, as well as consecutive parameters,
must be separated by at least one space (code: hex 0x20).
• Each individual command including parameters and data and
all responses are completed with CR LF (code: hex 0x0D and
0x0A) and can have a maximum length of 80 characters.
• The dot is used for decimal separators in a floating-point
value (code: hex 0x2E).
The details given above generally comply with the
recommendations of NAMUR (NAMUR recommendations for the
design of electrical plug-in connectors for analogue and digital
signals in laboratory MSR devices. Rev. 1.1).
The NAMUR commands and the additional specific IKA
commands serve only as low level commands for communication
between the device machine and the PC. With a suitable terminal
or communications program these commands can be transmitted
directly to the device. The IKA software package, labworldsoft®,
provides a convenient tool for controlling device and collecting
data under MS Windows, and includes graphical entry features,
for motor speed ramps for example.
The following table summarises the (NAMUR) commands
understood by the IKA equipment.
NAMUR Commands Function
IN_PV_3 Read external actual temperature
IN_PV_4 Read actual speed (rpm)
IN_PV_5 Read actual torque (%)
IN_PV_80 Read viscocity

Appendix A “Range coecient“
Using the “Range coefficient“, the maximum viscosity that can be measured with a specific spindle can be quickly determined.
1. Identify the selected spindle and the viscometer spring sensor (lo-vi/me-vi/hi-vi l/hi-vi ll).
2. Find the “Range coefficient“ in below table.
3. Divide the range coefficient by the spindle speed.
E.g.: If you choose me-vi viscomter with SP-6 spindle: Range coefficient is 10,000. At speed of 10 rpm, the maximum viscosity (mPa•s)
is 10,000/10=1,000 mPa•s

For measuring spindles of SP-1, SP-2, SP-6 and ELVAS-SP, experiment has verified approximate turbulence transition situations in the
following conditions:
1. SP-1 lo-vi spindle, 15 mPas at 60 rpm, rpm/mPas = 4;
2. SP-2 lo-vi spindle, 100 mPas at 200 rpm, rpm/mPas = 2
3. SP-6 me-vi spindle, 100 mPas at 50 rpm, rpm/mPas = 0.5
4. ELVAS-SP, 0.85 mPas at 60 rpm, rpm/mPas = 70.6
If the rpm/mPas ratio exceeds above values, turbulent situation may occur to the spindles listed above.
For measuring spindles ranging from VAN-SP-1 to VAN-SP-5:
Artificially higher viscosity readings may be introduced by turbulence at speeds of above 10 rpm.
