Brookfield DV-II+ Programmable Viscometer - Manual (Page 16)

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.

PRINT
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.
