General Filtering Information
The AVG and FILTER menu items discussed on the following pages are best explained
by an example of how the filtering works in this indicator.
Filtering is used to counteract vibration of the scale. The A-D weight conversion
happens 100 times per second in the E1070. AVG is the number of conversions you
want to average. For example, if you pick 50, the unit will average the weight values
from the last 50 conversions or ½ second and uses that value for displayed data.
If you turn the filtering on you need to set the Constant. Typical values are between 1-
10. Set the number low for small vibration problems and higher for more dampening
effect.
The purpose of the Threshold is so the indicator will respond quickly to large weight
changes. Threshold is the amount of weight change, in calibration units, beyond which
the filter will be temporarily disabled. For example, if you set this to 10 lbs, a weight
change over 10 pounds occurring during the sample time (½ sec. in our example) will
disable the filter until the weight change during the sample time drops below 10 lbs.
AVG (Averaging of A-D)
