Switching on the device

Check that the power supply matches the data on the rating plate. Plug the AC adapter into a standard mains socket in order to supply the device with power.

Introduction

After switching on the viscometer, the information screen is displayed for 4-5 seconds, showing the device name, software version 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: 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.

Level meter

Menu -> Viscosity -> Spindle -> Search

Observe the connection values and the ambient conditions (temperature, 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

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.

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.

• The small horizontal white line inside the circle, is moving vertically 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.

• 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.

Measurement principle

Useful information

The measuring principle of IKA Rotavisc is to use the stepping motor 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 measurement 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:

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/

”) 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-meters.

• The torque percentage is shown as “xx.x %”.

The equivalent units of measurement in the CGS system are calculated using the following conversions:

Torque

Spindle

dyne•cm mNm

lo-vi 673.7 0.0673

me-vi 7187.0 0.7187

hi-vi I 14374.0 1.4374

hi-vi II 57496.0 5.7496

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.

SI CGS Viscosity: 1 mPa•s = 1 cP Shear stress: 1 Newton/m

= 10 Dyne/cm

Torque: 1 Newton-m = 107 dyne-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 measurement 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.

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 range 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 accommodate special measurement circumstances. These accessories, while offering added capability to you, also contribute to an expanded measurement tolerance beyond the device accuracy of ±1 % of

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.

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 techniques. 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 begin with the standard viscometer spindles as detailed above. Viscosity calibration ﬂuids often show an accuracy of ±1% of the nominal volume!

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 container will result in an increase in viscosity readings.

First, download the latest driver for IKA devices with USB interface 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.

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.
