7 CHAPTER 3 CMRV-4500 APPARATUS DESCRIPTION CMRV-4500 unit/accessories The CMRV-4500 unit contains an aluminum block with a heater for warming the block. Nine viscometric cells are closely fitted into nine holes in the block (see photo). There are also two thermom- CMRV-4 unit with rotors inserted eter wells in the block.
8 Rotor crossbar The rotor crossbar is used to hold the loop at the end of the thread. It also serves as an indicator for (optional) manual timing of rotor rotation. Rotor locking pins The rotor locking pins String on rotor and pulley-wheel assembly are used to prevent unwanted rotor rotation. When the locking pin is lowered over the rotor crossbar (see photo), rotation is prevented. When the pins are in the raised (detent) position, the rotors are free to rotate.
9 Hook-weights Hook-weights are hung on the plastic ring at the free end of the thread to apply the required force to the rotor during yield stress and viscosity measurements. Nine disk weights, one hook-cage, and one larger hook-weight are provided. Weights vary depending on the ASTM Method used for testing.
10 Front panel operations CMRV front panel Control features CMRV front panel control features are simple and functional. The central switch on the front panel is the power switch for the unit. The lightemitting diodes (LEDs) above the switch indicate function of the heating and cooling systems. The Sensor connection on the right side of the panel mates with the cable from the pulleywheel optical sensor.
11 CHAPTER 4 SETUP The instructions in this chapter are for setting up a single CMRV-4500 with the Air/Water Heat Exchanger. For additional information on multiunit configurations, see APPENDIX D. CAUTION Do not apply power to the CMRV-4500 or Heat Exchanger until all connections are secure.

29 CHAPTER 6 PREPARING FOR CMRV TESTING/CALIBRATION The procedures in this chapter should be followed when preparing for CMRV-4500 testing or calibration. NOTE In the event that the protocols of your ASTM test method differ from any of the procedures outlined in this manual, the ASTM method should take precedence. A/W Heat Exchanger To prepare for operation of the CMRV-4500 unit, turn on the POWER switch on the upper rear panel of the Air/Water Heat Exchanger.
30 CAUTION! Exposure to acetone liquid or acetone vapor may damage the cover. 2. Turn on the CMRV-4500 (the green power indicator on the switch will light and the left panel lights will flash once). NOTE The CMRV cleaning procedure may be initiated from a "cold" CMRV; however, a calibration or profile should not be initiated until the instrument has completed a warmup period of approximately 45 minutes.
31 8. Wait for the CMRV-4500 to reach the cleaning temperature. NOTE When the CMRV-4500 cleaning cycle is activated, the internal heater raises the viscometer block temperature 2-3°C per minute to approximately 50°C. Precise temperature control is not necessary for cleaning. 9. When the CMRV-4500 has reached cleaning temperature remove the rotors and wipe excess oil from them. Gently place the rotors into a solvent-resistant container, such as a 500-ml glass beaker.
32 17. When you have finished cleaning the viscometer cells and rotors, click Stop Cleaning Cycle. Then click to exit the Cleaning ... window. NOTE After the cleaning cycle, you should permit the cells and rotors to dry for 15 minutes before introducing oil sample into the viscometric cells. Inserting rotors The viscometric cells are numbered from left to right when looking at the viscometer from the pulley-wheel side, with cells 1, 3, 5, 7, and 9 in the front row and cells 2, 4, 6, and 8 in the back row.
33 CHAPTER 7 CALIBRATING THE CMRV TEMPERATURE PROBE The CMRV temperature probe must be calibrated before performing the initial cell calibration or running temperature profiles. A complete calibration session involves setting temperature offsets in the VISCPRO software for key temperature checkpoints beginning at 80°C, then 50°C, then other temperatures at 5-degree increments from 0 to -40°C.
34 NOTE In each calibration session, the initial probe calibration must be performed at 80°C (see procedure below) before calibrating at other temperatures. When prompted by the VISCPRO software: "Do you want to zero the offset at 80°C before calibrating?", click YES the first time in the session that you attempt to calibrate at 80°C. Thereafter, click NO unless you would like to start the calibration over from the default offset value.
35 CHAPTER 8 CALIBRATING THE CMRV CELLS Initial calibration To ensure the accuracy of sample data, the CMRV-4500 cell calibration procedure must be completed after initial installation of the software. First complete the temperature probe calibration (see previous chapter) and instrument preparation (Chapter 6). Then follow the procedure in this chapter to calibrate the CMRV cells.
36 η = t3r = viscosity of the calibration standard (cP) time for 3 revolutions of the rotor (sec) Cell calibration procedure Calibration standards CANNON ® viscosity standard N105B is recommended for calibration at -20°C and -25°C. This calibration is required for running ASTM profiles included with the software. At -20°C, N105B has a nominal viscosity of 30,000 cP (mPa·s). At -25°C, N105B has a nominal viscosity of 56,600 cP (mPa·s).
37 wound around the rotor shaft. Then pass the thread below the crossbar and continue turning the rotor clockwise (as viewed from above) to wind 20 closely spaced turns of thread around the shaft below the crossbar without overlapping the turns. About 200 mm (8 inches) of thread will remain.
38 NOTES To reduce the chance of separating the mercury column during the heating phase of the temperature profile, you may wish to initially remove the calibrated thermometer from the CMRV unit. Store the thermometer in a vertical position. You may replace the calibrated thermometer when the CMRV has cooled to 30°C or lower.
39 7. Remove the Plexiglas® cover and align the pulley-wheel with the cell to be calibrated. 8. Place the thread from this cell over the pulley-wheel.

55 CHAPTER 10 SUMMARY OF TEST PROCEDURE In the ASTM D 3829, ASTM D 4684 and ASTM D 6821 test methods, a 10-ml sample is placed in a test cell, pre-heated to a specified temperature, and held at that temperature for a specified time to ensure complete solution of all components of the oil. The temperature of the cell is then lowered to the test temperature at a programmed cooling rate.
56 NOTE Most commercial oils do not have a yield stress when tested as specified by the SAE J300 Viscosity Classification. For the complete, definitive description of the ASTM D 4684 method, see the provided Standard Test Method for Determination of Yield Stress and Apparent Viscosity of Engine Oils at Low Temperature, Designation: D 4684, also available in the Annual Book of ASTM Standards, Volume 05.03. NOTE Nothing in this manual is intended to supersede the provisions of the ASTM test method.
57 The temperature profile for this method consists of a 1.5-hour soak at 50°C ± 1°C, a 2-hour nonlinear cool-down to the test temperature, and a 14-hour soak ± 0.02°C at the test temperature. The entire temperature profile, up to the point of measuring yield stress and viscosity, requires 17.5 hours.

59 CHAPTER 11 RUNNING PROFILES NOTE The guidelines in this section are not intended to supercede any test method. Always refer to the method for validation of any test procedure. Test preparation To run a temperature profile, first prepare the CMRV-4500 for testing (see Chapter 6). Make sure that the Air/Water Heat Exchanger POWER switch is on and that the unit is operating normally. Procedure 1. Place 10 ml of test oil in each of the viscometric cells to be used.
60 Winding rotors 7. To wind the rotors in preparation for the profile, slide the pulleywheel assembly along the track until the pulley is aligned with the first viscometric cell. Use the engraved lines on the slide bar as a guide to determine the proper position of the left side of the pulleywheel block. 8. Place the loop of a thread over the left end of the crossbar at the top of the rotor shaft. 9.
61 cover (Step 9.2.6 in the ASTM D 4684-98 method and step 9.1.6 in the ASTM D 3829 method). The tubing may be removed, along with the cover, prior to viscosity/yield stress testing. 14. Whatever the methodology, the purge should continue throughout the temperature profile using dry gas at a flow rate between 20 and 30 milliliters per minute. Starting a profile 1.
62 5. At the conclusion of the temperature profile you are ready to test samples. See Chapter 11 for the test procedure. Profile operation notes Instrument Status window During the profile, the Instrument View window will display the current status of the profile, the current test temperature, the desired temperature, time elapsed, and the time remaining until the yield stress and viscosity tests should be run. Display data is normally updated every 0.5 seconds.
63 Adjusting temperature at the end of a profile In the event that the CMRV instrument fails to attain the desired temperature at the conclusion of a profile, it is possible to adjust the instrument temperature using the following procedure: 1. Wait until the profie is completed and the Temperature Correction button is active. 2. Click in the Thermometer Temperature field and type the current temperature (as indicated by your calibrated thermometer) to the nearest 0.
64 Zooming in To view a section of the profile graph in greater detail, click and drag (press and hold down the left mouse button) the cursor to "draw" a box around the desired graph area. Then release the mouse button. The graph will be redrawn to include only the selected area. Zooming out To reduce the graph magnification, click the Refreshing the graph If you are displaying the profile graph while a temperature profile is running, you may not be viewing the most current temperature data.
65 CHAPTER 12 MEASURING YIELD STRESS AND VISCOSITY NOTE The guidelines in this section are not intended to supercede any test method. Always refer to the method for validation of any test procedure. Yield Stress and Viscosity testing should take place shortly after the profile is completed. NOTE ASTM D 4684 requires completion of yield stress and viscosity tests within 30 minutes of the conclusion of the profile.
66 ASTM D 3829 and 4684 specify an initial weight of 10-grams, and increase of weight in 10-gram increments. ASTM D 6821 specifies an initial weight of 2.5 grams and increase of weight in 2.5-gram increments. 6. Ensure that a Sample ID has been entered for each sample. Then click for the desired sample. OR use the Tab key to highlight the yield stress icon and then press R. The Yield LED (lightemitting diode) on the CMRV-4500 will glow and the Start Test button will begin flashing rapidly. 7.
67 10. If testing viscosity for the sample, follow the directions for viscosity testing (see Measuring Apparent Viscosity, next page). 11. Repeat steps 1-10 to perform yield stress/viscosity tests for all remaining cells to be tested in order from left to right. Notes on yield stress testing Step 9 (see previous section) is required for ASTM D 3829. The ASTM D 4684 method is a pass-fail method for fresh oils.
68 5. Press the flashing Start Test button and proceed immediately to step 6. 6. Lift the locking pin and release the weight by lowering your hand quickly and smoothly. The CMRV-4500 will measure the speed of rotor rotation by timing the revolution(s) of the pulleywheel as the weight falls. NOTE The total number of rotations measured by the CMRV-4500 during the viscosity test depends on the viscosity of the sample and the values chosen in the Advanced Settings box.
69 Notes on ASTM methods The protocols for measuring viscosity differ considerably between the ASTM methods. For further information on the methodology used to measure viscosity, consult the applicable ASTM method. Printing yield stress/viscosity test results To print the CMRV data form, including viscosity and yield stress test results: 1. Open and/or configure the appropriate analysis. 2.

107 CHAPTER A APPENDIX A — TROUBLESHOOTING Instrument status window not updating Check serial cable connections. If the status field in the Instrument View window indicates the CMRV is idle, then give the command to initiate the desired operation. If the temperature control lights on the controller are lit or blinking, close the Instrument Status window and reopen it. If temperature control lights on the controller are not lit or blinking, you may have a controller problem.
108 Check the level of the water/antifreeze mixture in the exchanger reservoir and add more mixture if necessary. Also check for pinched hoses or obstructions in the hoses/connectors. If necessary, detach the hoses per manual instructions, remove any obstructions, and reconnect the hoses. If these steps do not solve the problem, the relay in the controller or the Air/Water Heat Exchanger may be defective. Yield stress or viscosity test results inconsistent.

111 CHAPTER C APPENDIX C — THERMOMETRY Kinematic viscosity and temperature Kinematic viscosity is an extremely temperature-sensitive measurement a change of 1°C can sometimes lead to a viscosity change of 10 percent or more. Therefore, it is not surprising that temperature measurement and control are the most common problems encountered by laboratories performing accurate kinematic viscosity measurements.
112 NOTE Different thermometers have different installation requirements. Refer to the information included with the thermometer in use for specific installation instructions. ASTM thermometer tables The following tables show the ASTM thermometers available from CANNON® Instrument Company: CANNON® Mini-Rotary Viscometer CMRV-4500 Instruction & Operation Manual Version 1.
113 NOTE International shipments may be subject to special shipping regulations. ASTM D 445 — Checking the ice point Frequency To achieve an accuracy of ± 0.02°C for calibrated kinematic viscosity thermometers, a check at the ice point must be made. New thermometers should be checked monthly for the first six months, then once every six months. CANNON® Mini-Rotary Viscometer CMRV-4500 Instruction & Operation Manual Version 1.
114 Method The following text outlines procedures for checking the ice point of a thermometer. The text is adapted from: 1994 Annual Book of ASTM Standards, Volume 05.01, Method E77 ASTM Method E77 contains a detailed procedure for the measurement of ice points. The instructions listed here are specifically designed for the mercury-in-glass “kinematic viscosity” thermometers described in Table 2, and may not apply to other thermometers.
115 NBS Monograph150: Joining separated mercury columns The following text outlines procedures for joining separated mercury columns in thermometers. The text is adapted from: NBS MONOGRAPH 150 Liquid-In-Glass Thermometry Wise, Jacquelyn A. NOTE Many inquiries are received concerning separated mercury column which occur especially during shipment. Since no means of avoiding such occurrences has yet been found, some directions for joining mercury may be helpful and are described below.
116 Organic liquid procedures The procedure for thermometers containing organic liquids is similar. Separated liquid in the stem can be vaporized and permitted to drain down the capillary. Another method consists of gently tapping the stem above the separation against the palm of the hand, forcing the organic fluid to break away from the wall of the capillary and flow down the bore to join the main column.
117 CHAPTER D APPENDIX D — MULTI-UNIT CONFIGURATION Introduction The CMRV 4000 Series instrument have been designed to permit multiunit configurations of up to four CMRV units. Configuration is accomplished via a “daisy-chain” technique using RS-485 connections. A multi-unit interface kit containing all required items for multi-unit configuration is available from CANNON® (Catalogue # 9728-R40 for 120V units; #9728-R45 for 240V units).
118 3. Plug the converter’s RS-232 25-pin connector into the COM port you selected for multi-unit configuration during installation of the CMRV software. If you are using COM 1, a DB-25 to 9-pin adaptor may be required. 4. Select a CMRV unit as the first in the “daisy chain” and attach the three wires from the converter to the ABG connection marked IN on the RS-485 port on the back of the first CMRV chassis as follows (see diagram): Attach the red wire to IN-A. Attach the white or brown wire to IN-B.
