Use this key to set the AZT window division size and time window in sec-
onds. The division size you pick defines a range above and below zero.
When scale weight is inside this range for the number of seconds you
picked, ½ of the weight will be zeroed. The indicator will repeat removing ½
the weight every X seconds. X being the number of seconds you have
picked.
If you press the AZT soft key, follow these instructions:
1. The current value for the AZT
window size, in divisions, is
shown. Press ENTER to accept
this value or key in a new value
and press ENTER. . .
The current time window in seconds
for AZT is displayed.
2. Press ENTER to accept this time
period or key in a new value and

Use this key to set up the Harmonizer filtering to counteract vibration of the
scale. A full explanation is given below. See Appendix 2 for tips on using
Harmonizer.
The A-D weight conversion happens 60 times per second in the WPI-135.
AVG is the number of conversions you want to average. For example, if you
pick 30, the unit will average the weight values from the last 30 conversions
or ½ second and uses that value for displayed data.
The next choice you have is for turning the Harmonizer filtering on or off. If
you turn the Harmonizer filtering on you need to set the Harmonizer Con-
stant. Typical values are between 1-10. Set the number low for small
vibration problems and higher for more dampening effect.
The purpose of the Harmonizer Threshold is so the indicator will respond
quickly to large weight changes. Harmonizer Threshold is the amount of
weight change, in calibration units, beyond which the Harmonizer 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 Harmonizer until the weight change during the sample time
drops below 10 lbs.
If you press the FILTER soft key, follow these instructions:
1. The display shows the current
value for the number of samples
to average. Press ENTER to
accept this value or key in a new
value and press ENTER. . .
The display shows the state of the
Harmonizer filtering( ON or OFF).
In the SimPoser software the
Harmonizer constant choices
are 1 through 10. This setting
is to be made in the "real
world" on a working system so
there are more menus avail-
able from the front panel.
