This manual intended for use with CAP 2000+ series viscometers which have serial numbers beginning with a prefix of “CPN” .

CAP1000 and 2000 Viscometers with a serial number prefix of “CP” require a different manual. Please contact Brookfield or your authorized dealer/representative to obtain this manual.

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:

Viscosity:	CGS	SI	Comment
Viscosity:	P or cP	Pa•s or mPa•s	0.1 Pa•s = 1 P (= 100 cP)
Shear Rate:	Sec-1	Sec-1
Speed:	RPM	RPM
Temperature:	°C	°C

The CAP 2000+ Viscometer outputs data to a parallel printer in the CGS and SI units:

	CGS	SI	Comment
Viscosity:	P or cP	Pa•s or mPa•s	0.1 Pa•s = 1 P (= 100 cP)
Full Scale Range (F.S.R.):	%	%

I.5 Installation

DO NOT lift the viscometer by the handle or head! LIFT only by the base console or column!

1)Set the viscometer on a clean level bench surface.

2)Removeshippingfoaminsert(P/NCAP-122)fromtheplateareaontheCAPViscometer. Store the foam insert for future use when shipping or transporting CAP Viscometer.

3)Verify that the viscometer’s power requirements match your power source BEFORE connecting it to power.

The AC input voltage and frequentcy must be within the appropriate range as shown on the back of the viscometer head.

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 printer and the CAP 2000+ are off when connecting cables.

I.6 Safety Symbols and Precautions

Safety Symbols

The following explains safety symbols which may be found in this operating manual.

Indicates hazardous voltages may be present.

Caution: HOT surface.

Refer to the manual for specific warning or caution information to avoid personal injury or damage to the instrument.

Safety Overview

If this instrument is used in a manner not specified by the manufacturer, the protection provided by the instrument may be impaired.

This instrument is not intended for use in a potentially hazardous environment.

In case of emergency, turn off the instrument and then disconnect the electrical cord from the wall outlet.

I.7 Key Functions

Figure I-3 shows the control keys on the face of the viscometer display panel:

NUMERIC 0 - 9

These keys are used for data entry

ENTER

This key accepts entered data.

STOP / ESCAPE

Stops cone spindle rotation at any time. Exits data entry field.

DELETE

This key clears entered values for input selections.

This key sends data to the parallel printer.

RUN

HOLD TIME

This key selects time entry mode (wait time before spindle rotates).

SPINDLE

This key selects the cone spindle entry mode.

TEMP

This key selects the temperature entry mode.

I.8 Viscosity and Temperature Display

Viscosity is displayed in either P=Poise or cP=Centipoise (CGS system) or Pa•s=Pascal seconds or mPa•s=milliPascal seconds (SI system). If the viscosity measurement is over range, “EEEE” will be displayed. Brookfield recommends a minimum torque reading of 10% when making viscosity measurements. If the torque value is between 0 and 10%, the display will flash to indicate an under range condition. If the viscometer final reading is below zero, negative values will be displayed.

Temperature is displayed in °C=degrees centigrade.

I.9 Cleaning

Instrument, Keypad & Painted Surfaces:

Clean with dry, non-abrasive cloth. Do not use solvents or cleaners.

Immersed Components (spindles/cones) and temperature controlled plate:

Note: Sample plate and spindle may be hot. Use care when using solvents.

All immersed components are made of carbide steel. Clean with non-abrasive cloth and solvent appropriate for sample material that is not aggressive to immersed components.

Do not use metal objects to clean the plate surface, as scratching of the plate may occur and comporomise cone calibrations.

Solvent Trap:

SolventTrap (P/N C1K-63) is made ofTeflon. Clean with non abrasive cloth and solvent

appropriate for sample material that is not aggressive to Teflon.

Do not use metal objects to clean the plate surface, as scratching of the plate may occur and compromise cone calibrations.

Immersed components (cone spindle) may be at an elevated temperature. Use caution when cleaning hot surfaces. Use caution when applying solvents to hot surfaces. Refer to the MSDS for the specific solvent for proper handling techniques.

Note: When cleaning, take care not to apply excessive force which may bend the spindle shaft or otherwise damage the instrument.

II.GETTING STARTED

II.1 Power On

Turn the power ON using the switch located on the rear of the base console.

The start-up screen will be displayed for four seconds and will indicate the viscometer model, version number and torque range.

The instrument will be set to the default temperature:

CAP L Series Viscometer	25.0°C
CAP H Series Viscometer	50.0°C

If the CAP 2000+ Viscometer is connected to a PC via the serial port on the rear of the base console, the main screen display is EXTERNAL.

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 configured 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 functions screen, then selecting 1=RPM or 2=1/SEC and pressing ENTER.

The CAP2000+ can be configured 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 choosing 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 CAP2000+ has been configured, the instrument must be turned OFF. The configuration 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.
