I. INTRODUCTION
The CAP Series Viscometers are Cone and Plate geometry high shear rate instruments with
integrated temperature control of the test sample material. The CAP 1000+ is a fixed shear rate
viscometer rotating at 750 RPM and 900 RPM. The instruments operate by digital setting and
display; rotational speed can be automatically timed to stop. High shear rate viscosity measure-
ments are made over various viscosity ranges depending upon the cone spindle and the rota-
tional 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 pos-
sible 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 CAP1000+ can also be ordered with a single, customized speed between 5 and 1000 rpm.
In this case, the CAP can offer, when necessary, low shear rate capability.
The CAP 1000+ Viscometer selectably display in either the CGS or SI units (see page 7):

I.4 Installation
Note: DO NOT lift the viscometer by the handle or display panel! LIFT by the base console
or column!
1) Set the viscometer on a clean level bench surface.
2) Remove shipping spindle blank and foam packing from CAP Viscometer. Store the
spindle blank in the spindle case. Use again only when transporting CAP Viscometer.
3) Verify that the viscometer’s power requirements match your power source BEFORE
connecting it to power.
TheACinputvoltageandfrequencymustbewithintheappropriaterangeasshownonthe
name plate of the viscometer.
Note: The CAP Viscometer must be earth grounded. Use the three (3) wire power cord! Do
not alter!
4) Connect the power cord to the viscometer and to the power supply (source).
5) If using a printer, connect the printer cable to the printer port and printer.
Note: Ensure that both the priner and the CAP-1000+ are off when connecting cables.

I.7 Viscosity and Temperature Display
Viscosity is displayed in either P=Poise or cP=Centipoise (CGS system) or Pa•s=Pascal sec-
onds or mPa•s=milliPascal seconds (SI system). If the viscosity measurement is over range,
“EEEE” will be displayed. Brookfield recommends a minimum reading of 10%. If the display
value is between 0 and 10%, the unit display will flash to indicate an out of range condition. If
the viscometer settles out with a final reading below zero, negative values will be displayed.
Temperature is displayed in °C=degrees centigrade.

II. GETTING STARTED
II.1 Power ON
Turn the power ON using the switch located on the rear of the base console.
The display will sequentially show BROOKFIELD, then the model of the viscometer and the
version number. After about four seconds, the main screen will be displayed (Figure II-1),
indicating the temperature of the sample plate. The instrument will be set to the default tem-
perature.

Special Functions
Units of measure and speed of rotation may be selected through the special functions screen.
This screen is accessed by pressing the STOP key during instrument power up.
The CAP-1000+ can be configured to operate at 750 RPM or 900 RPM. This selection is set by
choosing 1=SPEED in the special functions screen, then selecting 1=750 RPM or 2=900
RPM and pressing ENTER.
The CAP-1000+ can be configured to display viscosity in one of four units: Poise (P), Centi-
poise (cP), Pascal Seconds (Pa•s) or milliPascal seconds (mPa•s). This selection is set by
choosing 2=U in the special functions screen, selecting 1=P, 2=cP, 3=Pa•s, or 4=mPa•s,and
then pressing ENTER.
Once the CAP-1000+ has been configured, the instrument must be turned OFF. The configu-
ration will be stored in memory.
II.2 Cone Spindle Selection and Setting
Raise the viscometer handle to its highest position.
The CAPcones have viscosity ranges as shown inAppendix A. After selecting the appropriate
cone for the viscosity range to be utilized, carefully attach the cone to the viscometer as shown:
Be sure to align the flats on the spindle shaft with the thumb screw.

Whenusing the solvent trap, connectit to thecone adapter bysliding it up,passing the slotby
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 firmly 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 first 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
C LIBR TE? YES/NO
Figure II-3
Normally there is no requirement to perform a cone calibration. Cones supplied at the time of
order are calibrated to the viscometer prior to shipment.
Note: 1. CAPViscometers 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).

Brookfield Engineering Labs., Inc. Page 10 Manual No. M02-312
2. Cones entered as 11 through 99 must be first calibrated following the directions in
Appendix B.
If you are not going to calibrate the cone, continue by pressing the NO key then ENTER. The
viscometer will display the MAIN SCREEN (Figure II-1).
If you are going to calibrate the cone, press the YES key, refer to Appendix B, and follow the
calibration instructions under Cone Calibration.
II.3 Speed Setting
The CAP1000+ is a single speed viscometer. It is supplied from the factory in two configura-
tions: standard and custom. The speed of rotation is shown in the lower right corner of the
display.
Standard
TheCAP1000+Viscometer issuppliedwithtwo speeds: 750RPMand 900 RPM. All CAP1000+
Viscometers are factory-set at 900 RPM. To change the setting, press and hold the STOP 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 CAP1000+ Viscometer is configured to operate at one speed as specified 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
Press the TEMP key and the current temperature setting will blink. The default temperature on
start-up is 25.0°Con low temperature models and 50°Con 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
Note:The temperature can be set in increments of 0.1°C.
Use the number keys to type in the required set point.
Use the ENTER key to accept th 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 tempera-
ture set point, allow sufficient time for the plate to reach the desired temperature. It is
recommendedtohavethespindleincontactwiththeplatepriortointroducingthesample
material to ensure that the spindle is also at the temperature of test. Brookfield
recommends using the solvent trap at all times to enhance the temperature control of the
samplematerial. Afterinsertingthesamplematerialontotheplate,lowerthespindleand
solvent trap and allow sufficient time for thermal equilibrium prior to starting the test.
