II. GETTING STARTED

II.1 Autozero

Before readings may be taken, the Rheometer must be auto zeroed. 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 II-1, the screen indicates that the DV-III Ultra 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).

No key press is necessary. After a short pause the display will read

“REMOVE SPINDLE, LEVEL

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 Ultra auto zeros.

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 Ultra is ready for use (Figure II-2).
