In Figure 5-3, the offset DVP-94Y 3 has been selected as indicated by the blue circle.

The creation of a Temperature Offset requires input of the offset value and a name. The offset value must be in the
range of -9.9 to 9.9˚C. The Name can be up to 14 characters long. To delete an existing Temperature Offset, first
select the offset from the list, then press the Delete command key at the bottom of the screen.
The use of a Temperature Offset will be indicated in the Temperature field displayed in the Configure Viscosity Test
screen with a (o) beside the Live indication.
The Temperature menu also allows the user to initiate control over a connected temperature control device such as
the AMETEK Brookfield Thermosel (HT-106 controller) or Water Bath (model TC-XX0SD or TC-XX0AP). Establish
control over the external temperature controller by selecting Temperature Controller in the Temperature menu (see
Figure 5-2). Press the Test Connection command button to verify that communication has been established between
the DVNext and the temperature controller. Be sure that the temperature controller is turned on prior to pressing
the Test Connection button. The Default Temperature screen also allows the user to set a Default Temperature. The
Default Temperature is the set point value that will be used by the DVNext when a test (Viscosity Test or Yield Test)
is not in use. To set the Default Temperature first, enter a temperature value and second check the Default Between
Tests check box.
TIP: Use a Default Temperature when the test program includes a change in temperature and set the value equal
to the first temperature control point in the test. At the conclusion of the test, the control device will be reset to the
first temperature set point which will minimize the time required between tests.
The Temperature screen also allows you to choose which temperature probe will be used for data collection and
temperature control. When the DVNext is controlling temperature through an external device, there may be two
temperature probes available for data collection: 1) the temperature probe connected to the DVNext (Probe) and
2) the temperature probe associated with the temperature control device (Controller). Press either Probe or
Controller in the Temperature menu.
Printer Setup
The DVNext is configured for use with the Dymo 450 printer. No other printers can be utilized with the rheometer.
Printer Setup allows the user to choose from three different configurations for print out.
Label Small:
A small label (1.13-inch x 3.5 inch) that allows for printing of limited data for a single data point. The
label stock is available from AMETEK Brookfield; part number GV-1048 (standard) or GV-1082
(long life).
Label Large:
A large label (2.31-inch x 4.0 inch) that allows for printing of a complete set of parameters for a single
data point. The label stock is available from AMETEK Brookfield; part number GV-1049 (standard) or
GV-1083 (long life).
