Model 574 Programmable Counting System (PCS)
16 - GSE Scale Systems
the selected filter selection is proportional to the selected
increment, parameter P111. Therefore if the auto-filter is
not performing as desired, the increment may be adjusted
upward to improve the stability or downward to improve
the response time (if the application does not require a
specific increment).
Refer to table 2, Filter Setup selections for a complete list
of all the selections for P116. Note that all these choices
also apply for Multi-Scale applications, ie P126 and P136
for a 2nd and 3rd scale respectively.
*
Note that for the auto-filter selections, the full scale
response times listed are not indicative of the time
required for the system to respond to a full scale input
change but rather an indication of the relative filtering
that will be performed when the weight signal has
achieved a steady state. In effect, selection 16 has the
same steady state filtering effect as selection 6.
P117.XX Rate=
This parameter specifies how often the display is updated
with new data. For example, if 0.1 is selected, the 574
will write data to the display once every six times an
Analog/Digital conversion is made, since the A/D
converter updates every 0.02 seconds, selections from
0.01 to 20.0 seconds are available. This parameter also
sets the transmission rate for continuous transmits.
Press <ENTER> to cycle through the available
selections. When the correct one is displayed, press
<SELECT> to advance to the next parameter.
P118.XX Zrnge
This parameter specifies how much zero can be removed
in terms of % of Full Scale. This is ideal for tank
weighing applications to prevent accidental ZERO
operations and for Canadian applications which have a
4% or less requirement. Press <ENTER> to cycle
through the available selections. When the correct one is
displayed, press <SELECT> to advance to the next
parameter.
P119.XX Linrz
This parameter enables or disables the Multi-Point
Linearization feature. Press <ENTER> to toggle
between the enable or disable selection. When the correct
one is displayed, press <SELECT> to advance to the
next parameter. When all selections are complete, press
<ZERO>. If any of the calibration related parameters
were changed, such as Full Scale, the 574 will now
prompt you to perform a calibration. If you wish to re-
calibrate, press <ENTER> and refer to the section on
Calibration operation.If you do not wish to perform a
calibration at this time, press <CLR> to skip the
calibration. If any changes were made, the system will
inform you and ask you to press <ENTER> to save the
modifications. To undo any changes, press <CLR>.
Then press <ENTER> again to exit the Setup Mode.
NOTE:
If you should decide to return to the Setup Mode during
the exit process , press any key other than <ENTER> or
<CLR>.
P120 to P129
govern the same basic weighing setup as P110 thru P119
except instead of applying to scale 1, it sets up scale 2.
P130 to P139
