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.

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.

1. The rst X readings are collected, placed in theaveraging buffer,averagedand the

average value is 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 output signal.

2. Data averaging is not applied to temperature.
