Introduction
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xed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 measurements are made
over various viscosity ranges depending 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 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.

Cone Spindle Selection and Setting
When using the solvent trap, 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:

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. 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. Conesenteredas11through99mustberst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).

II.3 SPEED SETTING
The CAP1000+ 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 CAP1000+ Viscometer is supplied with two speeds: 750 RPM and 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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
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°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
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 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temperaturesetpoint,allowsufcient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. BYK-Gardner 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.

17
Hold Time Settings / Run Time / Printing
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
seconds.
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: With a run time of zero, the hold time will not be used.
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.
At the end of a timed speed execution, data will automatically be sent to the printer
port. To print a heading, press and hold the STOP/ESCAPE key and press the
PRINT key.

Accuracy of Measurement
III. OPERATION
III.1 ACCURACY OF MEASUREMENT
Table III.1 indicates the accuracy of the viscosity measurement with CAP spindles
1-6. This accuracy depends on both the rotational speed of the cone and the
percent of full scale range (in Poise) at which viscosity is measured. The accuracy
for viscosity data provided by CAP Viscometers is the indicated percentage of the
full scale range. See Appendix A for information on how to determine Full Scale
Viscosity Range (FSR).
Please contact BYK-Gardner for accuracy information for CAP spindles 07-10.

Repeatability / Making Viscosity Measurements
III.2 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 de- crease 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.
Contact BYK-Gardner or your local BYK-Gardner Representative for details on the
above information.
III.3 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 list has 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. The default temperature
(25°C) is used for low temperature instruments (i.e., CAP1000+L). The
default temperature for high temperature is 50°C (i.e., CAP1000+H). 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) to save some time.
b) The cone calibration procedure (Appendix B) 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 (CAP1000+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 (CAP1000+H).
d) If a printer is to be used, it should be connected (AC power & viscometer to
printer cable). The CAP1000+ will print automatically when a reading is taken if
the printer is connected and “on line.”
Select and attach the cone (Section II.2).
