The Grams scale represents the weight required to drive the paddle through the test fluid at a rate of 200 rpm. The gravity drive system specified in ASTM D562 required that the weight be varied until 100 revolutions were achieved in 30 seconds (200 rpm). The KU-2 drives the unit at 200 rpm automatically and provides the grams value that would be required on the gravity drive system. The grams scale is not a viscosity unit. The Centipoise scale is available through a correlation originally defined in the ASTM test method. Since this value is based on the Krebs Unit, it is not equivalent to centipoise values determined using other types of viscometers, such as the Brookfield RVDV-I+. The centipoise values displayed on the KU-2 are for reference only. Comparisons to measured values from other instruments should not be made. I.9 Cleaning Make sure the instrument is in a decent working environment (dust-free, moderate temperature, low humidity, etc.). Make sure the instrument is on a level surface. Hands/fingers must be clean and free of residue sample. Not doing so may result in deposit build up on the upper part of the shaft and cause interference between the shaft and the pivot cup. Be sure to remove the spindle from the instrument prior to cleaning. Note left-handed thread. Severe instrument damage may result if the spindle is cleaned in place. Instrument and Keypad: Clean with a dry, non-abrasive cloth. Do not use solvents or cleaners. Immersed Components (spindles): Spindles are made of stainless steel. Clean with a non- abrasive cloth and solvent appropriate for sample material. When cleaning, do not apply excessive force, which may result in bending spindles. Brookfield Engineering Labs., Inc.

6) For Pint & 1/2 Pint Cans: Place the sample container directly on the can adapter mounted on the viscometer base. 7) Move the Viscometer handle down to the lowest position. KU1-73 (1/2 pint adapter) This will automatically immerse the spindle into the KU1-74 fluid. If the correct amount of fluid has been put into the (pint adapter) container, the surface of the fluid will be at the immersion mark of the spindle. Figure 6 Brookfield Engineering Labs., Inc.

272cP of data will print as soon as the Hold reading switch is moved to the down position (Figure 7). The display unit selector switch may be used to change the display. ----g ---.-KU ---cP 11) Raise the handle to the top position. This stops the spindle Figure 7 from rotating. Note: When using 1/2 pint cans, you must lift the can and then tilt slightly to remove the spindle. 12) Loosen the thumb screw and remove spindle for cleaning. Note: Do not remove the thumb screw. If dropped, it may fall into the sample. II.3 Troubleshooting If the operating handle is in the DOWN position and the display locks up and/or the spindle does not rotate the following should be checked: • Be sure the HOLD switch is in the UP position. If the hold switch was in the DOWN position prior to engaging the operating handle, dashes (——) or the previous reading may appear in the display. • The KU-2 requires a shutdown (power off) period of at least 30 seconds before it can be operated properly. If the unit had previously been turned off and immediately turned back on (without a 30 second shutdown period) both the display and rotation may temporarily lock up. If you experience these problems, simply raise the operating handle, turn the unit off and wait a minimum of 30 seconds before turning the power back on. Brookfield Engineering Labs., Inc.

Page 11: Appendix A - Ku-2 Calibration Information
Appendix A - KU-2 Calibration Information The accuracy of the KU-2 is verified using viscosity standard fluids calibrated in Krebs Units, which are available from Brookfield Engineering Laboratories or your local Brookfield dealer/distributor/ representative. Note: Calibration should not be verified using the centipoise scale. The centipoise scale is for reference use only and is based on a correlation from the Krebs Unit details in the ASTM test method D562. Viscosity Standards are calibrated at 25°C. Available standards are listed in Table A-1 below: Table A-1 Brookfield Viscosity Standard Nominal Viscosity (KU) Temperature (°C) KU61 KU73 KU87 KU99 KU106 Brookfield Viscosity Standards We recommend that Brookfield Viscosity Standard Fluids be replaced in accordance with the expiration date on the label. These fluids can be stored under normal laboratory conditions. Disposal should be in accordance with local, state and federal regulations. Material Safety Data Sheets are available on our website: www.brookfieldengineering.com/support/documentation. Calibration Check Procedure The frequency of the calibration check should be based on your company's standard practice for test and calibration of instruments. 1) Select any two viscosity standards listed in Table A-1 to perform your calibration check. The viscosity standards are very temperature sensitive. The viscosity value of the fluid will change... - Page 12 6) After you have recorded results in KU, then move the Selector knob to the "gm" position and record your reading in grams. If you are using a printer, three measurements will be sent to the printer and will print out as soon as the Hold Display switch is switched back to the DOWN position. Interpretation of Calibration Check Results When verifying the calibration of the KU-2, the instrument tolerance and viscosity standard fluid tolerance must be combined to calculate the total allowable error. The KU-2 is accurate to ± 11 grams, which is 1% of the full scale range in grams. The Brookfield Viscosity Standard is accurate to ± 1% of the stated viscosity in KU. The total allowable error should be stated in KU. Since the instrument accuracy is stated in grams, you will have to use the comparison table (Table A-2) and convert from grams to KU. Correct interpretation of your calibration results requires that you compare your readings in grams to the equivalent in KU. You must then bracket your reading with upper and lower limits based on the allowable error of ± 11.0 grams. Convert this acceptable range in grams (as defined by the upper and lower limits) to KU units. Example: Calculate the allowable error of the KU-2 using fluid KU106; the stated viscosity of the fluid is 104.8 KU. The viscometer indicated a measured viscosity of 105 KU and 410 grams. 1) Measured results from the calibration check in grams were 410 grams. Locate 410 grams on the conversion chart (Table A-2).
