II. GETTING STARTED
II.1 Autozero
Before readings may be taken, the Rheometer must be autozeroed. This is done each time the power
switch is turned on. The Rheometer will guide you through the procedure, as follows:
Turn power switch on; as shown in Figure 5, the screen indicates that the DV-III+ is in the standalone
mode (is not connected to a computer) and gives the version of the operating firmware (the built in
program which controls the instrument) and a two-digit alphanumeric code which indicates the
Model number (see Table D2 in Appendix D; the code tells the spring torque rating of your
Rheometer).
Figure 5
No key press is necessary. After a short pause the display will read “REMOVE SPINDLE, LEVEL
RHEOMETER AND PRESS THE MOTOR ON/OFF KEY TO AUTOZERO.” Before beginning the autozero
procedure, Brookfield recommends that you allow 10 minutes for the instrument to warm up.
After pressing the MOTOR ON/OFF key, the screen “flashes” for approximately 15 seconds while
the DV-III+ autozeros.
After 15 seconds the display reads “AUTOZERO IS COMPLETE REPLACE SPINDLE AND PRESS ANY
KEY.” Press a key.
The main screen is displayed and the DV-III+ is ready for use (Figure 6).
