I. INTRODUCTION

The CAP 1000+ Series Viscometers are high shear rate instruments with Cone Plate geometry
and integrated temperature control of the test sample material. Rotational speeds include 750
RPM and 900 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 1000+ can also be ordered with a single, customized speed between 5 and 1000 rpm.
In this case, the CAP 1000+ can offer, when necessary, low shear rate capability.

The CAP 1000+ Viscometer can display either CGS or SI units:

Figure II-3

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 Brookeld prior to shipment, but should still be veried 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.

Otherwise, there is no requirement to perform a cone calibration.

Brookeld Engineering Labs., Inc. Page 10 Manual No. M02-312A0607

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 Appendix B).

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).

If you are going to calibrate the cone, press the
calibration instructions under

II.3 Speed Setting

The CAP 1000+ is a single speed viscometer. It is supplied from the factory in two congura­tions: standard and custom. The speed of rotation is shown in the lower right corner of the
display.

Standard

The CAP 1000+ Viscometer is supplied with two speeds: 750 RPM and 900 RPM. All CAP
1000+ Viscometers are factory-set at 900 RPM. To change the setting, press and hold the
key during the power up sequence. Choose “1=SPEED (RPM)” from the special functions
screen and select the required speed. This selection will become the default speed.

Custom

The CAP 1000+ Viscometer is congured to operate at one speed as specied at the time of

order. This speed is indicated on the instrument serial tag.

To begin spindle rotation, press the RUN key.

II.4 Temperature Control Setting

YES key, refer to Section III, and follow the

Cone Calibration.

STOP

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 heater by entering 0 on the high temperature unit only.

Use the

Note:

ENTER key to accept the new set point.

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 sufcient time for the plate to reach the desired temperature.

Brookeld Engineering Labs., Inc. Page 11 Manual No. M02-312A0607

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. Brookeld

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 sufcient time for thermal equilibrium prior to starting the

test.

Temperature control on the high temperature unit can be restored by entering a setpoint between
50°C and 235°C.

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.

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.

Note: Run time will be shown on the default screen only when hold time is set to zero.

A run time of zero sets the viscometer to innite run mode. In this mode, the spindle will rotate

at the set speed for as long as the RUN button is pressed. When the RUN key is released, the
spindle will stop rotating.

Note:

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
test by pressing the RUN key. Press the

With a run time of zero, the hold time will not be used.

STOP/ESCAPE key and press the PRINT key. Then start the

1. Press RUN to begin a test.

2. Press and hold the RUN key for continuous rotation when 00 is the timer 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).

Brookeld Engineering Labs., Inc. Page 13 Manual No. M02-312A0607

III. OPERATION

The CAP 1000+ Viscometer is delivered from the factory with two available speeds for opera­tion at 750 rpm or 900 rpm. Information on how to access these speeds is detailed in section
II.3 “Speed Setting”. Your viscometer may operate at a different rotational speed based on what

was specied at the time of order. To determine what speed your viscometer has been set to,

power on the viscometer and note the operating speed on the main screen display.

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. Brookeld recommends that viscosity measurements be made be­tween 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 certicate of calibration that accompanied the instrument or

the display on power up.

23CAP 1000+ = Low Torque CAP 1000+ = 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 a speed setting that was selected at the time of order 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 1000+
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 denes 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 specication 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.

• 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.

Brookeld Engineering Labs., Inc. Page 16 Manual No. M02-312A0607

• 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 Verication

Accuracy of the CAP 1000+ Viscometer can be veried by performing a calibration verica­tion.

The cones/spindles that were shipped with the viscometer were calibrated to the viscometer by

Brookeld prior to shipment. If your viscometer was returned to Brookeld or an authorized
Brookeld 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 verication on each cone spindle to

ensure that each spindle is measuring correctly. 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 verication 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 verication is also 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 verication, you will need a mineral oil from Table III-5 or Table

III-6. Determine what range model CAP 1000+ 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, regardless of what your test calls for:

1. Put the cone in the down position, 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.

Figure III-1c Figure III-1d

4. Run a viscosity test and record the viscosity value when the reading has stabilized.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.

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.

A cone calibration should be performed when: 1) using a new cone for the rst time,

Note:

2) switching between two cones of the same number and 3) verication 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 1000+ 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 con-

trol.

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) prompted by the
screen.

Viscosity values are always entered in units of CENTIPOISE (cP) no matter what units

Note:

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 specied 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. Press the RUN key to start the calibration.

Brookeld Engineering Labs., Inc. Page 20 Manual No. M02-312A0607

Note: The calibration process may be cancelled at any time prior to pressing RUN by

pressing 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 1000+ 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 denitely 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 1000+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 1000+H).

d) If a printer is to be used, it should be connected (AC power & viscometer to printer

cable). The CAP 1000+ 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.

Brookeld Engineering Labs., Inc. Page 22 Manual No. M02-312A0607

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 poisonous,

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

temperature display may indicate a deection 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 mea-

surement is maintained within the limits specied in Table 3.1.

11. Read the results of the sample test on the printer or write down the test conditions and vis-

cosity 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.

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.

Brookeld publication,

“More Solutions to Sticky Problems” includes a more detailed discus-

sion of rheological properties and non-Newtonian behavior.

Brookeld Engineering Labs., Inc. Page 24 Manual No. M02-312A0607

Viscometer Related Variables

• Most uid viscosities are found to be non-Newtonian. They are dependent on Shear Rate and
the spindle geometry conditions. The specications 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 sufcient to cover the face of the cone
