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.
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.
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.
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.
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.
5. MEASUREMENT 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.
Note 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 5000 mPa⋅s. NO When the position of the sensor plates in the liquid is not at the same level, level the viscometer using the leveling feet so that the liquid surface will be leveled.
5-2 Basic Measurement Procedure The below is an example of the SV-10 at shipment. For the SV-100, the unit at shipment is Pa⋅s 1 With the power turned off, press the ON:OFF key. When the display is in the standby mode, press the START key. *1 After about 15 seconds, the measurement values are displayed. 2 During measurement, press the HOLD key as necessary, to freeze the display temporarily. To release the data hold mode, press the HOLD key again. *2 3 Press the STOP key to stop the measurement.
5-3 Changing Units The units of viscosity available are: mPa⋅s (millipascal second), Pa⋅s (Pascal second), cP (Centipoise), P (Poise). The correlation of the units are as follows: 1 mPa⋅s = 0.001 Pa⋅s = 1 cP =0.01 P The units of temperature available are: °C (Celsius) and °F (Fahrenheit). The unit selected upon power-on depends on the function setting. The unit selected at the factory before shipment is as shown below.
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.
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. Kinetic viscosity = Viscosity From this, Viscosity × Density = Density Viscosity2 Kinetic viscosity is obtained.
6-2-1 One-point Calibration 1 2 3 4 5 The below is an example of the SV-10. For the SV-100, the unit is Pa⋅s In the standby mode, press and hold the HOLD key to enter the calibration mode.

The below is an example of the SV-10. For the SV-100, the unit is Pa⋅s 6-2-2 Two-point Calibration 1 In the standby mode, press and hold the HOLD key to enter the calibration mode. " Cal " appears. 2 Select two-point calibration (Cal-2) and press the PRINT key to confirm. The standby mode of the twocalibration mode appears. Use the MODE key to switch between the calibration modes, one-point calibration (Cal-1) or two-point calibration (Cal-2). Press the STOP key to exit the calibration mode.
9 When the measurement of the first point has completed, clean the sensor plates, temperature sensor and protector and prepare the second standard viscosity fluid. From the previous page 10 Place the second standard viscosity fluid in the sample cup. Press the START key to start the measurement of the second point. 11 After the measurement, wait for the display to become stable and press the PRINT key. The measurement value blinks and is ready to be corrected.
6-2-3 Simplified Calibration Using Purified Water (SV-10 only) 1 Place the purified water in the sample cup. 2 Press the START key to measure the purified water. Confirm that the viscosity and temperature values are stabilized. 3 Press and hold the START key. The theoretical viscosity value(Viscosity × Density) of the purified water at the measuring temperature is displayed and all the displays blink. To cancel the operation, press the STOP key. The display returns to the status before calibration.

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.
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.
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.
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.
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.
