II. GETTING STARTED

II. Power ON

Turn the power

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

=SPEED CONTROL

in the

special func-

tions screen

, then selecting

1=RPM

2=1/SEC

and pressing

ENTER

The CAP 2000+ can be configured to display viscosity in one of four units:

Poise (P)

Centipoise

(cP)

Pascal Seconds (Pa•s)

milliPascal seconds (mPa•s)

. This selection is set by choos-

ing

2=Units of Measure

in the

special functions screen

, selecting

2=cP

3=Pa•s

=mPa•s

, and then pressing

ENTER

Once the CAP 2000+ has been configured, the instrument must be turned

OFF

. The configura

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.
