II.4SpeedSelecon
ere are 18 rotational speeds available on the DVE Viscometer. ese speeds correspond to the
standard LVF, LVT, RVF, RVT, HAT and HBT Dial Viscometer models, and they are combined
sequentially (see Table II-1).
Note: Speed changes are not instantaneous when motor is on. ere will be
some acceleration/deceleration time as speed changes are entered.

e Default screen displays the currently selected speed of rotation. Press the SPEED up/down arrow
keys to scroll through the list of available speeds until the desired speed is shown on the display.
TIP: When setting a test procedure, be aware if the data must be compared to another site.
If a comparison is required, it is best to utilize speeds that are traditionally associated
with the torque range of the viscometer. is will ensure that all test sites will be able to
reproduce the test method exactly.
Speeds: LV - 0.3, 0.6, 1.5, 3, 6, 12, 30, 60
(RPM) RV/HA/HB - 0.5, 1, 2, 2.5, 4, 5, 10, 20, 50, 100
Note: e DVE uses stepper motor technology for speed control. Some electronic
noise is normal. e noise level will vary with the selected speed.
