The DV-II

may also be programmed at Brookfield Engineering for “special” user spindles. These
“special” spindles will show up on the spindle scroll list starting with designation “AA” and
continuing through “AZ”. Contact Brookfield Engineering regarding your needs for special
spindles.

Speed Selection & Setting
There are 18 speeds programmed into the standard DV-II
+
. These speeds correspond to the standard
LVT, RVT, HAT, HBT, LVF and RVF dial models. If the DV-II
+
is an LV, the speed set will start
at speed 0.0. It will then scroll up through the LV speeds, pass through speed 0.0 again, and then scroll
up through the RV speeds at which point it will pass through speed 0.0 again and will then repeat the
above sequence. If the DV-II
+
is an RV (HA and HB) “type”, the inverse of the above will occur.
The DV-II
+
will start at 0.0 and scroll through the RV speeds, pass through 0.0 again and then scroll
through the LV speeds until it again reaches speed 0.0. The speed sets are described in Table 1.
The DV-II
+
may also be programmed with “special” speed sets. A list of special speed sets is
included in Appendix F. Please consult Brookfield Engineering or your local dealer/distributor for
any special speed requirements not addressed by the standard or special speed sets.
To select a Viscometer speed first press either the UP or DOWN arrow keys which will cause the
area to the right of RPM (on the bottom line) to display the currently selected speed. Figure 7 shows
the DV-II
+
had been operating at 6.0 RPM, and the current selected speed is 6.0 RPM.
