Test results (data files) can be saved to the internal memory of the DVNext or to a USB Flash Drive. These files can

be reloaded into the DVNext for review, analysis, or printing through the View Results function. A file of Test Results

that is saved onto a USB Flash Drive can be viewed on any DVNext Rheometer.

Within the View Results function, the user can access the internal memory of the DVNext Rheometer or any USB

Flash Drive that is connected to a USB port

. The rheometer will point to the USB Flash Drive according to the

order in which it is connected. The first USB Flash Drive that is connected will be referred to as #1 on both the View

Results screen and the Status Bar. As many as three USB Flash Drives can be connected to the DVNext at any time.

Results files that are displayed on the screen can be sorted by date of creation or by alpha/numeric name. This

sorting is selected by pressing the Navigation Icon

TIP: Manage Files function can be used to move Results files from internal memory to a USB Flash Drive.

The DVNext Rheometer will give on screen indications when the measurement is out of range of the instrument.

When the %Torque reading exceeds 100% (over range), the display of %Torque, Viscosity, and Shear Stress will be

EEEE (see Figure 2-20). If the %Torque value is between 0 - 9.9%, the data field label will flash. When the %Torque is

below zero (negative values), the display of Viscosity and shear Stress will be ----.

TIP: AMETEK Brookfield recommends collecting data only when the %Torque reading is between 10 - 100%.

Figure 2-20

Measurement data should not be collected when the %Torque reading is out of range. The out of range condition can

be resolved by either changing the speed (reduce speed when reading is out of range: high) or changing the spindle

(increase the spindle size when the reading is out of range: low).

TIP: When comparing data, the test method is critical. Be sure that you know the proper spindle and speed required

for the test method. If readings are out of range, this condition should be reported as the test result.

The DVNext Rheometer can communicate to a Dymo Label Writer 450 Turbo label printer.

This printer can be purchased from AMETEK Brookfield (Part No. GV-1046). The communication to the printer is by

USB (cable provided with the printer). When the printer is connected to the DVNext, the printer icon will be visible in
