cP (Viscosity) and SS (Shear Stress) values will be displayed as "- - - -" when the % (Torque) is

below zero.

Figure 18 is an example of the printed output of each of the above conditions.

II.7 Temperature Display

The DV-II+ will display the temperature measured by its RTD temperature probe. Temperature may

be displayed in either ˚C (Centigrade) or ˚F (Fahrenheit) units depending upon the start-up

operations. If the DV-II+ is started normally, the default temperature display will be in ˚C

(Centigrade) units as shown in the Figure 19:

Figure 19

However, if you press and hold the SELECT DISPLAY key while turning on the DV-II+ the

temperature will be displayed in ˚F (Fahrenheit).

If you turn on the DV-II+ with the temperature probe disconnected, or remove the temperature probe

at any point after power-up, the display will indicate “- - - -°C”.

The four “dashes” indicate the absence of the probe. If you were displaying temperature in

Fahrenheit units the C would be displayed as an F.
