Pressing the OPTIONS/TAB key “toggles” between the two port choices. To select a printer output
port, press the ENTER/AUTORANGE key while the desired choice is blinking. This will cause the
DV-II+Pro to direct all further printer output to the chosen port while remaining in the Setup
menu. You must press the ENTER/AUTORANGE key to select the ashing option.
III.2.5 Data Averaging
This feature will perform a “rolling” average on the displayed % torque value and all other
displayed viscometer data derived from % torque. You are allowed to select the number of
readings over which averaging is being done, with ten (10) readings as the maximum. There
will be an initial delay as the rst average is performed and then no apparent delay as the
following readings are averaged (the viscometer takes approximately 4 readings per second).
The rolling average is described as follows given the selected reading number ‘X’:
1. The rst X readings are collected, placed in the averaging buffer, averaged and
displayed.
2. The rst reading in the averaging buffer is dropped; the next reading (the X + 1
reading) is placed in the buffer and the buffer is again averaged and displayed. Step
2 is repeated indenitely until the viscometer is shut off or the user selects a different
number of readings to average. The number of readings to be averaged will include
zero (0) as an average so that this option may effectively be turned off without turning
the viscometer off.
Notes:
1. The data averaging will only be applied to the data displayed by the viscometer.
No data averaging will be applied to the torque analog output signal.
2. When data averaging is other than zero (0) or one (1), a ashing A will be displayed
to the left of the % Torque sign as shown below.
