Brookfield Engineering Laboratories, Inc. Page 20 Manual No. M14-023
II.8 Options
The Options Menu is accessed from the Home screen by pressing the OPTIONS Hot Key. Use the
Arrow Keys to select from the following functions:
• RUN UNTIL Set the end condition for the test: Time, Torque or Temperature.
• SERVICE No user access.
• ABOUT Display start up screen with viscometer torque and firmware version
number.
• LANGUAGE Choose from available languages.
• TMP. OFFSET Set an offset value for the DVP-94Y temperature probe (optional).
• TEMP. UNITS Set the unit of temperature measurement.
• VISC. UNITS Set the unit of viscosity measurement.
• TEST VIEW Set the primary display parameter and the mode of data display.
II.8.1 Run Until
The DV1 Viscometer provides an end condition for the viscosity measurement. The end condition
defines when the spindle will stop its rotation and a final data point will be shown on the display.
The end condition currently in use on the DV1 can be identified by choosing RUN UNTIL in the
Options Menu. The end condition will be displayed on the screen along with the parameter value.
End conditions are defined in the table below:
End
Condition
Display
Name Parameter Range
Time Time Hours : Minutes : Seconds 00 hours : 00 minutes : 00 seconds to
99 hours : 99 minutes : 59 seconds
Torque Torq. % Torque 0 - 100
Temperature Temp. Degrees and Tolerance -100° - 300°C +/-5.0°C
Press the SELECT Hot Key while viewing the Run Until Options screen. This will present the Run
Until screen with the currently selected End Condition name underlined. Use the Arrow Keys to
change the End Condition selection. Three Hot Keys are available:
BACK: Exit the Run Until Options screen and return to the Options Menu.
SELECT: Accept the currently underlined End Condition and advance to the
Run Until parameter entry screen.
HOME: Return to the Home screen.
Run Until Time requires that a time value be selected. Time is entered by first selecting hours (from
00 to 99) then minutes (from 00 to 99) and then seconds (from 00 to 59). Use the Arrow Keys to
adjust each parameter. Use the SELECT Hot Key to move from hours to minutes to seconds. Use
the BACK Hot Key to move back from seconds to minutes to hours. The time value is accepted by
pressing the SELECT Hot Key while on the seconds display.
TIP: Be sure to select a time value that provides sufficient time to allow for equilibrium of the
torque sensor. A short time value may result in erroneous data if the torque sensor has
not achieved a stable deflection for the measurement condition. Brookfield recommends
a minimum time value of 20 seconds. However, this can be reduced based on user
judgement by observing when the torque stabilizes.
