I.6 Key Functions
Figure I-1 shows the control keys on the face of the DV-I+ Viscometer. The following describes each
key's function.
UP ARROW
This key is used to scroll UP (in an increasing
value direction) through the available speed or
spindle tables.
DOWN ARROW
This key is used to scroll DOWN (in a decreasing
value direction) through the available speed or
spindle tables.
Tp Note: Pressing and holding the
DOWN ARROW key
during the POWER ON will enable the
temperature display to be read in
°
C or
°
F.
See Section II.1.
MOTOR
ON/OFF MOTOR ON/OFF
Turns the motor ON or OFF.
SET
SPEED
SET SPEED
Causes the DV-I + to begin running at the currently selected speed. Used for Time to Torque
and Timed Stop tests. (See Section II.9 - Timed Modes for Viscosity Measurement.)
AUTO
RANGE
AUTO RANGE
Presents the maximum (100% torque) viscosity attainable (known as full scale range) for the
spindle speed selected. This feature is functional when the motor is running. Viscometer
allowable error is 1% of the maximum (100% torque) viscosity value; minimum recommended
viscosity range is 10% of the maximum viscosity value.
Note: Pressing and holding the AUTO RANGE key during power on will enable the
viscosity display to be changed between CGS and SI units (see Section II.5).
SELECT
SPINDLE
SELECT
SPINDLE
SELECT SPINDLE
Initiates spindle selection on the first press and then selects the currently scrolled-to spindle
when pressed a second time. Used for Time to Torque and Timed Stop tests. (See Section
II.9 - Timed Modes for Viscosity Measurement.)
