I. INTRODUCTION
The CAP 2000+ Series Viscometers are medium to high shear rate instruments with Cone Plate
geometry and integrated temperature control of the test sample material. Rotational speed selection ranges from 5 to 1000 RPM. Viscosity measurement ranges depend upon the cone spindle
and the rotational speed (shear rate). Viscosity is selectively displayed in units of centipoise
(cP), poise (P), milliPascal seconds (mPa•s) or Pascal seconds (Pa•s). Temperature control of
sample is possible between either 5°C (or 15°C below ambient, whichever is higher) and 75°C
or 50°C and 235°C depending on viscometer model.
The CAP 2000+ Viscometer can display either CGS or SI units:

Special Functions
Units of measure and speed control may be selected through the special functions screen. This
screen is accessed by pressing the STOP key during instrument power up.
The CAP 2000+ can be congured to control speed by either rotations per minute (RPM) or
shear rate (1/SEC). This selection is set by choosing 1=SPEED CONTROL in the special func-
tions screen
, then selecting 1=RPM or 2=1/SEC and pressing ENTER.
The CAP 2000+ can be congured to display viscosity in one of four units: Poise (P), Centipoise
(cP), Pascal Seconds (Pa•s) or milliPascal seconds (mPa•s). This selection is set by choos-
ing 2=Units of Measure in the special functions screen, selecting 1=P, 2=cP, 3=Pa•s, or
4=mPa•s
, and then pressing ENTER.
Once the CAP 2000+ has been congured, the instrument must be turned OFF. The congura-
tion will be stored in memory.
Note: When operating the CAP 2000+ with shear rate as the method of speed control, the
shear rate value entered may be adjusted based on the shear rate multiplier for the
spindle. For example: if using cone 4 (shear rate multiplier of 3.33), an entered shear
rate of 51 1/SEC will be displayed as 50 1/SEC.

II.2 Cone Spindle Selection and Setting
Thumb Screw
Solvent Trap
Cone Spindle
Raise the viscometer handle to its highest position.
The CAP cones have viscosity ranges as shown in Appendix A. After selecting the appropriate
cone for the viscosity range to be utilized, carefully attach the cone to the viscometer as shown
in Figure II-3.
Be sure to insert the spindle completely into the adapter sleeve; align the at (see Figure I-1)
on the spindle with the thumb screw and then tighten.
When using the solvent trap (Figure II-2), connect it to the cone adapter by sliding it up,
passing the slot by the thumb screw and turning the trap clockwise onto the thumbscrew.
Slide the cone up into the adapter as far as it will go and hand lock it in place with the thumb
screw. Tighten the thumb screw rmly and securely.
Press the SPINDLE key. The display will change to the spindle entry screen. Using the number
keys, type in the required spindle number.
Two digits must be entered for the cone number. For cone 01 through 09, the rst number
remains as “0”.
Note: The default cone setting on power-up will be the last cone entry prior to shutting off
the viscometer.
After the correct two (2) digits have been entered, press the ENTER key and the cone will be
accepted for viscometer calculations. The screen will display the following message:

Spindle 04
CALIBRATE? YES/NO
Figure II-4
If you are using the CAP Viscometer for the rst time or have just received the instrument back
from being serviced, press YES and see Section III. Cones supplied at the time of order are
calibrated to the viscometer by Brookeld prior to shipment, but should still be veried with a
calibration check prior to use for the rst time. Cones purchased separately at a later time by
the user must also be calibrated prior to making viscosity measurements. If you have 2 cone
spindles that are identical (have the same number), you must do a cone calibration when you
swap them.
Otherwise, there is no requirement to perform a cone calibration.
Note: 1. CAP Viscometers allow for only one cone at a time of the same cone number to
be calibrated to the viscometer. Multiple cones of the same cone number must each
be calibrated to the viscometer before operation (refer to Section III).
2. A special feature of the CAP series viscometers allows the user to perform a cone
calibration with viscosity standard uids.
3. Cones entered as 11 through 99 must be rst calibrated following the directions in
Section III.
If you are not going to calibrate the cone, continue by pressing the NO key, then the ENTER key.
The viscometer will display the MAIN SCREEN (Figure II-1). Should you subsequently run
a test and observe that the instrument is reading all “0s”, the “P” for Poise is ashing, and the
“%” symbol is ashing, then the cone spindle you are using is not calibrated. You must perform
the cone spindle calibration to rectify the problem.
If you are going to calibrate the cone, press the YES key, refer to Section III and follow the
calibration instructions under Cone Calibration.
II.3 Speed Setting
The CAP 2000+ is a variable speed viscometer. The speed of rotation is shown in the lower
right corner of the display. To change the speed of rotation, enter the new speed using the
number keys. The new speed will be shown in the lower right hand corner of the display. To
accept the new speed, press ENTER.
The new speed may be cancelled by pressing ESCAPE before pressing ENTER.
To begin spindle rotation, press the RUN key.
Note: The speed cannot be changed while the motor is running.
Speed control may be congured to either shear rate or rotations per minute (see Special Func-
tions in section II.1). Data entry for speed selection is the same in either conguration.
Data entry must be in whole numbers.
Brookeld Engineering Labs., Inc. Page 13 Manual No. M02-313E1209
Page 14
II.4 Temperature Control Setting
Press the TEMP key and the current temperature setting will blink. The default temperature on
start-up is 25.0°C on low temperature models and 50.0°C on high temperature models.
The temperature ranges are:
Low temperature: 5°C (or 15°C below ambient, whichever is higher) to 75°C
High temperature: 50°C to 235°C
Use the number keys to type in the required set point. The temperature can be set in increments
of 0.1°C. You can turn off the temperature control on a high temperature unit by entering 0.
Use the ENTER key to accept the new set point.
Note: Thermal equilibrium of the sample and of the spindle must be considered for best
measurement results. Upon powering up the Viscometer or after changing the tem-
perature set point, allow sufcient time for the plate to reach the desired temperature.
It is recommended to have the spindle in contact with the plate prior to introducing the
sample material to ensure that the spindle is also at the temperature of test. Brookeld
recommends using the solvent trap at all times to enhance the temperature control
of the sample material. After inserting the sample material onto the plate, lower the
spindle and solvent trap and allow sufcient time for thermal equilibrium prior to
starting the test.
II.5 Hold Time Settings
Hold time sets the time period between when the RUN key is pressed and when the spindle
begins to rotate. This time period is normally used to ensure thermal equilibrium of the sample
and spindle. The hold time range is 0 to 999 seconds.
Press the HOLD TIME key and the current hold time will blink on the default screen. Use the
number keys to type in the required hold time and press the ENTER key.
Note: When the hold time is set to zero, it is not displayed on the default screen. Run
time will be shown on the default screen only when hold time is set to zero.
Note: With a run time of zero, the hold time will not be used.
II.6 Run Time
Run time sets the time period of spindle rotation. The run time range is 0 to 999 second.
Press the RUN TIME key and the current run time will blink on the default screen. Use the
number keys to type in the required run time and press the ENTER key.
A run time of zero sets the viscometer to innite run mode. In this mode, the spindle will rotate
at the set speed for as long as the RUN key is pressed. The display will shown “MANUAL”.
When the RUN key is released, the spindle will stop rotating.
Note: With a run time of zero, the hold time will not be used.
Brookeld Engineering Labs., Inc. Page 14 Manual No. M02-313E1209
Page 15
The time required for reading stabilization will depend on the speed of rotation and the nature
of the test sample. Longer runs times are recommended at lower speeds.
II.7 Printing
Pressing the PRINT key at any time sends information on test parameters to the printer port.
However, viscosity, full scale range and shear stress data will only be printed after it is rst
displayed during a test run.
To print a heading, press and hold the STOP/ESCAPE key and press the PRINT key. Then start the
test by pressing the RUN key. Press the PRINT key whenever data is desired during the test.

The TIMER (SEC) column will indicate the accumulated time of running at the moment the
print key is pressed while the cone is rotating. This time value will not include the hold time.
At the end of a test, data will automatically be sent to the printer port.
II.8 Run and Stop Keys
The RUN key has three functions:
1. Press RUN to begin a test.
2. Press and hold the
RUN key for continuous rotation when 00 is the run time setting.
3. Used in executing a cone calibration.
The
STOP key has three functions:
1. Stops the cone rotation at any time.
2. Pressing and holding the STOP/ESCAPE key during power up selects the special func-
tions mode where the viscosity display units and speed of rotation may be changed.
(Section II.1)
3. Pressing and holding the STOP and PRINT keys simultaneously executes the printing of
a new heading (Section II.7).

III. OPERATION
The CAP 2000+ Viscometer rotates a precisely machined cone spindle over a temperature
controlled plate shearing the test sample over a range of speeds from 5 to 1000 RPM. This
provides a comprehensive capability to analyze materials for viscosity behavior as a function
of both shear rate and temperature. Tests can be run in standalone mode or under PC control.
This chapter explains how to use the CAP 2000+ toward these objectives.
III.1 Full Scale Range and Accuracy of Measurement
Full Scale Range (FSR) viscosity is the maximum viscosity that can be measured and occurs
when the % torque is 100. Brookeld recommends that viscosity measurements be made be-
tween 10 and 100% torque.
There are two tables to consult for viscosity range information, depending on which torque
model viscometer you purchased. To determine which torque model you have, consult the se-
rial tag of your viscometer or the certicate of calibration that accompanied the instrument or
the display on power up.
23CAP 2000+ = Low Torque CAP 2000+ = High Torque
Full Scale Range (FSR) is based on the cone spindle your are using, the torque model of your
viscometer, and the speed of spindle rotation. The tables below provide information on FSR
by torque model for the most common factory set speeds:

You can also determine FSR for any speed selection that is not in the above tables by doing a
simple calculation:
• For Low Torque CAP instruments:
Cone range constant / (22.7 * N) = FSR (Poise) where N = RPM
• For High Torque CAP instruments:
Cone range constant / N = FSR (Poise) where N = RPM
The last column in the above tables shows this calculation.
III.2 Accuracy of Viscosity and Temperature
The following tables indicate the accuracy of the viscosity measurement for the CAP 2000+
Viscometer using CAP spindles 01-10. This accuracy depends on both the rotational speed of the
cone and the percent of Full Scale Range (%FSR) in Poise at which the viscosity is measured.
Accuracy is stated in Poise (P) and is calculated as a % of the FSR viscosity.
To calculate accuracy:
• Determine FSR viscosity in Poise for the torque model, cone spindle, and speed of rotation,
using the information in Tables III-1 or III-2.
• Find the column that best denes the speed of rotation used for the measurement and your
reported % FSR from the measurement.
• Consult the table below to determine the accuracy of your measurement
• Multiply the accuracy by the FSR viscosity if you need your accuracy stated in Poise.

The specication of temperature accuracy on CAP Viscometers is stated below:
LOW TEMP UNITS
• In ambient conditions of 15°C to 30°C, accuracy is +/- 0.5°C when the temperature set point
on the viscometer is 5°C to 75°C.
• In ambient conditions outside of 15°C to 30°C, accuracy is +/- 1.0°C when the temperature
set point on the viscometer is 5°C to 75°C.
HIGH TEMP UNITS
• In ambient conditions of 15°C to 30°C, accuracy is +/- 0.5°C when the temperature set point
on the viscometer is 50°C to ≤100°C.
Brookeld Engineering Labs., Inc. Page 19 Manual No. M02-313E1209

Page 20
• In ambient conditions of 15°C to 30°C, accuracy is +/- 1.0°C when the temperature set
point on the viscometer is 101°C to 235°C.
• In ambient conditions outside of 15°C to 30°C, accuracy is +/- 2.0°C when the temperature
set point on the viscometer is 50°C to ≤100°C.
III.3 Calibration Verication
Accuracy of the CAP 2000+ Viscometer can be veried by performing a calibration verication.
The cones/spindles that were shipped with the viscometer were calibrated to the viscometer by
Brookeld prior to shipment. If your viscometer was returned to Brookeld or an authorized
Brookeld Dealer, then any cones/spindles that were returned for service will have been cali-
brated to the viscometer prior to shipment.
When you receive the instrument, perform a calibration verication on each cone spindle to
ensure that each spindle is measuring correctly. Use the appropriate viscosity standard uid
dened in Table III-5 or III-6 for each spindle. This will ensure that everything is in good
working order and that the instrument and/or cone spindles have not experienced a change
during shipment. If the calibration verication fails then you can take advantage of the CAP
Viscometer’s unique feature which allows the operator to recalibrate each cone spindle to the
CAP Viscometer (See Section III.4).
Calibration verication of your viscometer should also be performed when viscosity readings
with your product are suspect. Verifying the calibration will determine if the cone needs to
be recalibrated to the instrument. This will help you to determine if the discrepant readings
on your product are due to cone/instrument performance, or your method or your product.
Complete cone recalibration is discussed in Section III.4.
To perform a cone calibration verication, you will need a mineral oil from Table III-5 or Table
III-6. Determine what range model CAP 2000+ Viscometer you have (Low Torque or High
Torque), which temperature range (L = Low, H = High; consult the instrument serial tag) and
what cone your are using.
You must use the following method to verify calibration of each cone spindle.
1. Attach solvent trap and spindle and lower viscometer head. Put the cone in the down posi
tion, and make sure that the solvent trap is covering the spindle.
2. Allow the viscometer to stabilize for at least 30 minutes at 25°C (Low Temp units) or at
60°C (High Temp) if the temperature that you normally operate is different; otherwise, wait
5 minutes, then make sure the cone is in the down position and that the solvent trap is on.
3. At the end of the temp stabilization period, dispense the appropriate volume of uid (consult
Table III-5 or Table III-6). Figure III-1 shows how to dispense the uid onto the plate and
determine visually if the amount is appropriate.

Page 21
Figure III-1a Figure III-1b
Figure III-1c Figure III-1d
4. Run a viscosity test and record the viscosity value when the reading has stabilized.
5. Compare the recorded viscosity to the actual value of the standard and verify that it falls
within the accuracy limits stated in Tables III-3 and III-4. The allowable accuracy is cal-
culated by adding 1% of the value for the viscosity standard uid to the product of (%
accuracy x FSR) for the spindle/speed in use. This combined value (in Poise or cP) gives
an allowable window around the actual viscosity value of your standard. If your measured
viscosity falls within this window, the verication passes.
Example:
CAP-03 spindle on High Torque Low Temp CAP Viscometer running at 900 RPM.
Viscosity standard has nominal value at 25ºC of 354 cP or 3.54 P; 1% = 3.54 cP or
0.0354 P. FSR = 8.33 P from Table III-2; use 2% accuracy calculation from Table
III-4 since viscosity standard < 50% of FSR. Accuracy for viscometer with CAP-03
spindle is therefore 2% X 8.33 P = 0.1666 P. Add 0.0354 P to 0.1666 P to determine
the allowable accuracy ± 0.2020 P. The measured viscosity value with CAP-03 spindle
must be within ± 0.202 P or 20.2 cP of the viscosity standard to pass calibration.
6. If the test fails, repeat again to make sure that every step was performed correctly. If the
test fails again, perform a cone calibration according to the procedure in Section III.4.

III.4 Cone Calibration
A special feature of the CAP Series Viscometers allows the user to perform a cone calibration
using Viscosity Standard Fluids. This eld calibration will accommodate any wear on the tip
of the cone which may result from contact with the plate. This also allows the user to purchase
a new cone spindle and perform the calibration in your plant
Brookeld Engineering Labs., Inc. Page 22 Manual No. M02-313E1209
Page 23
Note: A cone calibration should be performed when: 1) using a new cone for the rst time,
2) switching between two cones of the same number and 3) verication of calibration
provides data outside of the acceptable range.
Refer to Tables III-5 and III-6 to choose the calibration uid for the spindle being calibrated.
1. Turn on the CAP 2000+ Viscometer.
2. Attach solvent trap to coupling shaft.
3. Attach spindle.
4. Place appropriate amount of sample onto the center of the Viscometer plate directly below
the spindle.
5. Pull down the handle, locking it into the lowest position, placing the spindle in contact with
the plate.
6. Lower the solvent trap.
Note: The solvent trap must be utilized when calibrating to ensure proper temperature
control.
7. Select the spindle to be calibrated by using the SPINDLE key.
8. Select YES for CALIBRATE and press ENTER.
9. Enter the appropriate values for temperature (°C) and viscosity (cP) value printed on the
label.
Note: Viscosity values are always entered in units of CENTIPOISE (cP) no matter what
units have been selected as unit of measure for normal operation.
100 cP = 1P; 1cP = 1mPa•s; 1000 cP = 1Pa•s
Note: The Viscometer temperature control must be identical to the specied temperature for
the viscosity standard when executing the calibration. Normally calibration will be at
25°C for “L” Series CAP Viscometers and 60°C for “H” Series CAP Viscometers.
10. Allow at least 30 minutes for thermal equilibrium of the plate, calibration uid and spindle,
from instrument cold start.
11. Select the spindle speed.
All of the spindles used with the low torque CAP 2000+ instruments should be calibrated
at 100 RPM when using the recommended viscosity standard uids. This practice will
calibrate the instrument at approximately the middle of the Full Scale Range.
Spindles used with the high torque CAP 2000+ and the recommended viscosity standard
uids may be calibrated at any speed.
Brookeld Engineering Labs., Inc. Page 23 Manual No. M02-313E1209
Page 24
12. Press the RUN key to start the calibration.
Note: The calibration process may be cancelled at any time prior to pressing RUN by press-
ing the ESCAPE key.
When calibration is complete, spindle rotation will stop and the “CALIBRATION COMPLETE”
screen is displayed. (See Figure III-2). Press ENTER to continue.

III.5 Repeatability
The CAP 2000+ Viscometer is repeatable to ±0.5% of the full scale viscosity range (FSR). Due
to shear heating considerations which occur in high shear rate instrumentation, the measurement
of NIST Viscosity Standard Fluids at rotational speeds above 900 RPM will show a decrease
in viscosity with an increase in rotational speed (shear rate).
Normal forces due to the shearing of a viscoelastic uid (such as paint) are accounted for in
the CAP Series Viscometers by weight on the spindle column of 3.4 Newtons (340,000 Dynes)
total force. This is done to avoid having the cone lift off the plate, thereby changing the cone
plate geometry and producing incorrect viscosity readings. For normal forces greater than
3.4 Newtons (340,000 Dynes) total force, additional externally mounted weights are required.
However, more weight means more wear on the cone and plate. Additional weights should
only be considered when denitely required and removed when not required.

III.6 Making Viscosity Measurements
The following procedure is recommended for making a viscosity measurement.
With the viscometer on a clean, level surface, connect it to the proper power supply (Section
I.4).
1. Turn the power switch
ON (Section II.1).
The procedure assumes that the following have been done:
a) If the viscometer has been “off” for an extended period (i.e., overnight) a “warm up”
period of 30 minutes is suggested. You may choose to warm up at the temperature of
test. If a cone calibration is to be done immediately after the warm up period, temperature should be set to 60°C (calibration temperature for high temperature instruments)
or 25°C for low temperature instruments to save some time.
b) The cone calibration procedure should have been done for all cones which are used
with the instrument. Cone calibration is only required when a new cone (i.e., replacement for lost/damaged cone) is used, or when calibration check fails.
c) When making measurements with low temperature instruments (CAP 2000+L), the
solvent trap may not be required (for the containment of solvents and/or prevention of
sample “drying”). The trap should be used for all measurements with high temperature instruments (CAP 2000+H).
d) If a printer is to be used, it should be connected (AC power & viscometer to printer
cable). The CAP 2000+ will print automatically when a reading is taken if the printer
is connected and “on line.”
2. Select and attach the cone (Section II.2).
Notes: a. Lock the cone tightly into the adapter.
b. When measuring volatile samples such as paints and coatings, and when using
either a high temperature CAP 1000+H or CAP 2000+H, the solvent trap must be put
in place over the cone to prevent the test sample from drying out during the rotation
of the cone.
3. Set the temperature control (Section II.5).
4. Set the cone number.
5. Lower the handle placing the cone onto the plate. Lock the handle into its lowest position.
Drop the solvent trap over the cone.
Note: Allow ten (10) minutes for the cone to come to equilibrium temperature with the
plate.
6.
Secure trap on shaft. Solvent trap may be hot, spindle & plate too. Raise the handle.
Place the sample to be measured onto the plate below the cone and solvent trap. Don’t use
plastic spatulas/syringes if the plate temperature is above 50°C. Refer to Table III-5 or
III-6 for recommended sample sizes. Lower the cone and solvent trap.
Brookeld Engineering Labs., Inc. Page 25 Manual No. M02-313E1209
Page 26
Notes: a. Lower the handle gently. DO NOT FORCE THE CONE ONTO THE
PLATE.
b. The sample must completely cover the face of the cone and extend beyond
the edge of the cone about 1.0 mm.
c. Release the solvent trap placing it onto the plate over the cone so it does
not touch the cone shaft.
The user should ensure that the substances placed under test do not release poison-
ous, toxic or ammable gases at the temperatures to which they are subjected to
during the testing.
7. Allow the cone, plate and sample to equilibrate to the temperature control setting.
Note: A minimum of one (1) to three (3) minutes equilibrium time is recommended, de-
pending upon the sample.
8. Set the Run Time for rotating the cone (Section II.6) and the Hold Time.
9. Put the printer on-line (optional, Section II.7).
10. Press the RUN key and execute the viscosity measurement.
Note: Due to the dynamics of shearing a uid in the CAP “H” series Viscometers, the tem-
perature display may indicate a deection from the equilibrium temperature setting
as the cone begins rotating at high shear rates. The temperature display may indicate
the temperature of the plate and the momentary changes show the cycling of the temperature control at high temperature. The precision of the viscosity measurement is
maintained within the limits specied in Table 3.1.
11. Read the results of the sample test on the printer or write down the test conditions and viscosity results from the viscometer display.
12. Relocate the solvent trap onto the cone adapter and raise the handle.
Caution: HOT surface.
13. It is recommended to remove the cone for cleaning. However, with care, the cone can be
cleaned in place.
Caution: HOT surface.
14. Clean the viscometer plate (refer to Section I.8).
Caution: HOT surface.
III.7 Computer Control
The CAP 2000+ Viscometer can be operated remotely under PC control when using the CAPCALC application software.
When advanced sample analysis is required, Brookeld CAPCALC application software can
control the CAP 2000+ Viscometer from a PC. CAPCALC for Windows requires Windows
Brookeld Engineering Labs., Inc. Page 26 Manual No. M02-313E1209
Page 27
Windows NT or higher. CAPCALC application software displays, prints and stores tabulated
data les (Brookeld, Excel).
CAPCALC software has automatic data capture (up to 200 data points per test) and graphical data display (rheograms) to facilitate analysis of test samples. The software also allows
temperature control of the sample plate for integrated viscosity/temperature tests between 5°C
and 75°C (CAP 2000+L) or 50°C and 200°C (CAP 2000+H) depending on viscometer model.
CAPCALC features include on-screen and printed plots of % F.S.R., viscosity or shear stress vs.
cone speed, shear rate, time or temperature. Also available are automatic calculation of Yield
Stress (Bingham Plastic or Casson) and Power Law Consistency Index.
Additional information on the communications protocol for CAP 2000+ is contained in
Appendix B
.

APPENDIX A - Variables in Viscosity Measurements
As with any instrument measurement, there are variables that can affect a Viscometer measure-
ment. These variables may be related to the instrument (Viscometer), or the test uid. Variables
related to the test uid deal with the rheological properties of the uid, while instrument variables
would include the Viscometer design and the spindle geometry system utilized.
Rheological Properties
Fluids have different rheological characteristics that can be described by Viscometer measure-
ments. We can then work with these uids to suit our lab or process conditions.
There are two categories of uids:
Newtonian - These uids have the same viscosity at different Shear Rates (different
RPMs) and are called Newtonian over the Shear Rate range they are
measured.
Non-Newtonian - These uids have different viscosities at different shear rates (different
RPMs). They fall into two groups:
1) Time Independent non-Newtonian
2) Time Dependent non-Newtonian
The time dependency is the time they are held at a given Shear Rate (RPM). They are nonNewtonian, and when you change the Viscometer spindle speed, you get a different viscosity.
Time Independent
Pseudoplastic - A pseudoplastic material displays a decrease in viscosity with an increase
in shear rate, and is also known as “shear thinning”. If you take Viscometer readings from a low to a high RPM and then back to the low RPM,
and the readings fall upon themselves, the material is time independent
pseudoplastic and shear thinning.
Time Dependent
Thixotropic - A thixotropic material has decreasing viscosity under constant shear
rate. If you set a Viscometer at a constant speed, recording P values
over time, and nd that the P values decrease with time, the material is
thixotropic.
Brookeld publication, “More Solutions to Sticky Problems” includes a more detailed discus-
sion of rheological properties and non-Newtonian behavior.
Brookeld Engineering Labs., Inc. Page 28 Manual No. M02-313E1209
Page 29
Viscometer Related Variables
• Most uid viscosities are found to be non-Newtonian. They are dependent on Shear Rate and
the spindle geometry conditions. The specications of the Viscometer cone and plate geom-
etry will affect the viscosity readings. For example, if one reading is taken at 750 rpm, and a
second at 900 rpm, the two viscosity values produced may be different because the readings
were made at different shear rates. The faster the spindle speed, the higher the shear rate.
• The shear rate of a given measurement is determined by the rotational speed and the cone
angle.
• A repeatable viscosity test should control or specify the following:
1. Viscometer model
2. Cone used
3. Test temperature
4. Test speed [or the shear rate]
5. Length of time to record viscosity
6. Sample volume sufcient to cover the face of the cone

Command Description
<aaaaaa> Cone multiplier constant (hexadecimal). All cone multiplier constant values are six characters padded
with leading zeros.
<bb> (HI / LO) Indicates whether the instrument operates in the high (0°C to 235°C) temperature range or
the low (5°C to 75°C) temperature range.
<cc> Cone number (hexadecimal); all cone number are two characters padded with leading zeroes. All cone
values are two characters padded with leading zeroes.
<CR> Carriage return
<ddddd> Spring Constant (hexadecimal). The Spring Constant must be multiplied by 10,000 before transmis-
sion by the CAP 2000+. Use the base Spring Constant for the model, not an adjusted constant after
calibrating.
<eeeeee> Shear rate constant of a cone to be calibrated (hexadecimal). The CAP 2000+ must divide shear rate
constants by 10000 after they are received, and multiply shear rate constants by 10000 before sending
them out. All shear rate constant values are six characters padded with leading zeroes.
<ffff> % FSR (hexadecimal). % FSR values are multiplied by 100 before transmission from the CAP 2000+.
All FSR values are four characters padded with leading zeroes.

sion by the CAP 2000+. All shear rate values are six characters padded with leading zeroes.
<ss> Status byte, returned in hexadecimal format, see Table 2 for complete description. All status bytes are
two characters padded with leading zeroes.
<ttt> Temperature (°C) sent to or from the CAP 2000+ (hexadecimal). The CAP 2000+ must divide all tem-
perature values received by 10, and multiply all temperature values sent by 10. All temperature inputs
are three characters padded with leading zeroes.
<vvvvvv> Viscosity (P) sent to or from the CAP 2000+ (hexadecimal). The CAP 2000+ must divide all viscos-
ity values received by 1000, and multiply all viscosity values sent by 1000; all viscosity values are six
characters padded with leading zeroes.
<xxx> Firmware version number, in decimal format, multiplied by 100 by CAP 2000+ before transmission
(i.e. for rmware version 2.15, xxx would be 215).
<yyy> Speed (RPM) input (hexadecimal). All speeds are three characters padded with leading zeroes.
