II.6 Temperature Display in °F or °C Selection

Pressing and holding the DOWN ARROW key during power on will enable the temperature display

to be read in either degrees Fahrenheit or degrees Centigrade. To change the units format:

1. Turn the power OFF.

2. Press and hold the DOWN ARROW key and turn power ON.

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

The following screen depicts the changes to the default screen when displaying temperature in

the Fahrenheit scale and viscosity display in SI units:

II.7 Out of Range

Brookfield recommends taking viscosity readings between 10% and 100% of scale. The DV-I+

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 II-12:

cP EEEE S01

10 RPM % EEEE

Figure II-12

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-I+ flashes both % (Torque)

and cP (Viscosity) on and off:

cP 78.0 S01

10RPM20 % 7.8

Figure II-13

Negative % (Torque) will be displayed as shown in Figure II-14:

cP ---- S01

10RPM20 % -0.2

Figure II-14

Viscosity values will be displayed as “- - - -” when the % (Torque) is below zero.
