3.4 USER SET-UP PARAMETERS
The following is a detailed list of the parameters and options in the 8000. Be sure to
read this carefully, and select settings that will best fit the application.
NOTE: Factory default settings are shown in bold type.
3.4.1 Digital Averaging or Display Update Rate (AVG)
Function Option Description
AVG A1 Approx. 10 updates/second
1* Approx. 10 updates/second
2 Approx. 5 updates/second
4 Approx. 2 updates/second
8 Approx. 1 updates/second
16 Approx. .5 updates/second
A2 Approx. 10 updates/second
* Refers to the number of reading per average cycle
The Digital Averaging parameter is used to tailor the 8000's display update rate to your
application and environment. The circuitry in the 8000 takes weight readings at a rate
of approximately 10 per second.
Factors such as wind currents and vibrations can be read as changes by the scale's
weight sensor, thus 10 updates per second is too fast and the scale display appears to
be "bouncy". In order to filter or "smooth" out the display, the 8000 is equipped with an
averaging function.
The averaging function takes a series of weight readings and averages them together.
This smooths out the small changes caused by outside influences. The more readings
taken, the more stable the display will be.
However, as this number of readings per average increases, the update rate of the
display updates slows down. The above chart shows the relationship between the
number of readings per average and the display update rate.
The "A1" and "A2" setting refer to a software utility called "Auto Averaging". The update
rate of the display varies based upon the amount of motion taking place on the scale
platform.
"A1" allows for maximum speed of weighing while maintaining high stability at the final
weight reading. "A2" provides a more stable final weight reading than A1.
3.4.2 Automatic Zero Tracking (AZT)
Function Option Description
AZT .5 +/- .5 div zeroed
1 +/- 1 div zeroed
3 +/- 3 div zeroed
OFF none
