I.7 Key Functions
Figure I-3 shows the control keys on the face of the DV-I PRIME
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 change the
temperature display between °C and °F.
MOTOR
ON/OFF
MOTOR ON/OFF
Turns the motor ON or OFF.
SET SPEED
Causes the DV-I
PRIME 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/ENTER
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 accuracy 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).
ENTER Use to enter parameters in the Timed Stop Mode(see Section II.9.2).
TIMED OPTION
Used to select timed modes for viscosity measurement (see Section II.9), and to select temperature
offset mode (see Section II.9.4).
SELECT SPINDLE
This initiates spindle selection on the rst 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).
PRINT
Initiates print modes (see Section II.10.)
