II.7 Temperature Display

The DV-II

+ displays the temperature measured by its RTD temperature probe. Temperature may be

displayed in either ˚C (Centigrade) or ˚F (Fahrenheit) units, depending upon selection from the

Options menu. As received, the default temperature display will be in ˚C (Centigrade) units as shown

in the Figure 19:

cP 123.4 20.1C

10 RPM % 19.7

Figure 19

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 replaced by an

F. Accuracy of temperature measurement for the DV-II+ is shown in Table 1.

Printing

The DV-II+ will print data to an attached Serial (RS232) or Parallel (centronics) printer. The printer

must be attached to the appropriate rear panel output connector. See Appendix G for configuration

and connection requirements.

Data may be printed in two ways:

1. Pressing the PRINT key once (for less than three (3) seconds) will result in the printing of one

standard print line.

2. If the PRINT key is pressed and held for more than three (3) seconds, the DV-II+ will then begin

continuous printer output at a print rate interval selected via the Options menu (see Section III.4).

The display will show a flashing P in front of the % sign. See Figure 20.

To stop continuous printing, press the PRINT key for one (1) second. The flashing P will

disappear on the viscometer display.

Figure 21 is an example of the print strings for CGS and SI units.
