Note: 1. If the MOTOR is OFF or the RPM is 0.0, the maximum viscosity displayed will be 0.0

cP (or 0.0 mPa

s).

2. While the Viscometer is in the Auto Range mode, any data sent to an attached printer or

computer reflects the displayed values (i.e. Auto Range values).

Pressing and holding the AUTO RANGE key during power on will enable the selectable display to

be read in either CGS or SI units. To change the unit format:

1. Turn the power off.

2. Press and hold the AUTO RANGE key and turn the power ON.

The DV-II+ will retain the unit selection when the viscometer is turned OFF.

DV-II+ Viscometers without this function can be updated. Contact Brookfield or your local

Brookfield dealer for this service.

II.6 Out of Range

The DV-II+ gives indications for out of specification or out-of-range operation. When % (Torque)

readings exceed 100.0 % (over-range), the display changes to that shown in Figure 15:

Figure 15

EEEE will also appear when viscosity or shear stress are over range. You must change either speed

or spindle to correct this condition. If you operate at spindle speeds that produce % (Torque) below

10.0 % (under-range), the DV-II+ displays % (Torque), cP (Viscosity) and SS (Shear Stress)

preceded by a “?” as shown in Figure 16:
