3) The DV-III Ultra may be set-up to “handshake” (using XOn/XOff protocol) or not
handshake when connected to a serial printer. If you opt to use the handshake mode,
your printer is “on line”, all cable connections are correct and your printer is set for
handshake mode, then data should appear on your printer immediately. If it does not
appear, and instead you see the message:
“PRINTER IS NOT READY TURN ON/PRESS
ONLINE”
then you should turn the handshake option off. See Section V.2.
V.6 Timed Data Collection
The DV-III Ultra offers three methods of time control that may be used independently of the control
programs for making viscosity measurements described in IV.2 and IV.3. These techniques result
in a single data point collected at the end of the test. If multiple points are required, the rheometer
should be connected to a printer and set up with an appropriate print interval.
S
TIME TO TORqUE
The DV-III Ultra will record the amount of time required to reach the specified % torque value at
a single speed. Torque and speed are input using the number keys and
OPTIONS/TAB
key. The test
will begin immediately upon the press of the
ENTER
key.
The test will end when the specified torque level is reached (in either an upward or downward
direction). The data will be displayed as shown in Figure V-5. The
SELECT DISPLAY
key can be
used to view all measurement parameters. The
key can be used to send a single data line to
the printer.

Note:
If continuous printing was used during the test, it will be suspended when viewing
the test data or entering time to torque parameters.
S
TIMED STOP
The DV-III Ultra will operate at a single RPM for a specified period of time. Time and speed are
entered using the number keys and
OPTIONS/TAB
key. The test will begin immediately upon the
press of the
ENTER
key.
The test will end when the specified time interval has elapsed. The data will be shown as displayed
in Figure V-6. The
SELECT DISPLAY
key can be used to view all measurement parameters. The
key can be used to send a single dataline to the printer.
