When you are done programming the 4200, be sure to replace the access cover on the
back of the unit (4200 Tower, 4200M) or close the front cover (4200RSS) to maintain the
water resistant and dust-tight integrity.
SETUP PARAMETERS
The following is a detailed list of the parameters and options in the 4200, as well as a
description of how they affect the operation of the scale. Be sure to read these
descriptions carefully, and select settings that you feel will best fit your needs.
NOTE: Factory default settings are shown in bold type.

Auto-averaging, averaging disabled when stable, 128 readings per average when in motion
(approx. 20 updates/second)
The Digital Averaging parameter is used to tailor the 4200's display update rate to your
application and environment. The circuitry in the 4200 takes several weight readings every
second. In some instances because of factors such as wind currents and vibrations that
are read as changes by the scale's weight sensor, the maximum update rate is too fast and
makes the scale display appear to be "bouncy". In order to filter or "smooth" out the effects
of these factors, the 4200 is equipped with an averaging parameter. The averaging
parameter simply takes a series of weight readings and averages them together. This
smoothes out the small changes caused by outside influences. The more readings taken
per average cycle, the more stable the weight reading will appear. However, as this
number of readings per average increases, the rate at which the display updates slows
down. When selecting a setting for the Digital Averaging parameter, refer to the above
chart which shows the relationship between the number of readings per average and the
display update rate. Note that the analog filter setting (see next page) also affects the
display update rate.
