II.5 External Control
The DV-III Ultra Rheometer can be used in conjunction with Brookfield software, RHEOCALC
(V. 2. or higher). Through RHEOCALC, all rheometer functions are controlled by the computer.
The DV-III Ultra must be set to the external control mode to allow for proper communication with
RHEOCALC. To configure the external control mode, connect computer interface cable DVP-80
(RS-232) or DVP-202 (USB) to the port on the DV-III Ultra base before turning on the DV-III
Ultra. With the DVP-80 cable in place, the DV-III Ultra will present the screen shown in Figure
II-20 when it is turned on. If external control is selected, the DV-III Ultra will display Figure II-21
and only accept control commands from RHEOCALC software.

Note: The DV-III Ultra cannot communicate with RHEOLOADER or EZ-
Yield software in the external control mode. Choose "Stand Alone"
when presented with Figure II-20 if you want to use RHEOLOADER
or EZ-YIELD.
