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 flashing option.
IV.2.5 Data Averaging
You must press the
ENTER/AUTORANGE
key to select the flashing option.
Figure IV-12
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 first 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.
1. The first X readings are collected, placed in the averaging buffer, averaged and the
average value is displayed.
2. The first 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
indefinitely 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 output signal.
2. Data averaging is not applied to temperature.
3. When data averaging taking place, a flashing A will be displayed to the left of the
% Torque sign as shown in Figure IV-13.
