Cntby
This menu is used to set up the display to
count by increments of 1, 2, 5, 10, 20, 50,
100, 200, 500, 1000, 5000, or 10000. For
example, a Cntby of 1 would show the
rightmost active digit on the display changing
by increments of 1. A Cntby of 100 would
show the rightmost three active digits on the
display changing by increments of 100 units.
Use Cntby to adjust the display to a resolu-
tion consistent with the accuracy of the
system and reduce display flickering.
Example: For a 10,000 lb maximum weight
with a Form of XXXXX, a Cntby of 1 would only
be meaningful if your system accuracy was
+/-.01% of maximum load. A more typical
accuracy would be +/-3%. Since 3% of
10,000 lbs is 300 lbs, a more realistic Cntby
for this system would be 200.
Note that the selection for Form affects how
the Weigh II interprets the Cntby value.
Table 4-1 shows some examples of how
these are related.
Form Cntby Example Value
(incremented digit
underlined)
xxx.xx 1 397.25
xxx.xx 100 397.00
xxxxx 1 39725
xxxxx 100 39700
xxxxxoo 1 3972500
xxxxxoo 100 3970000
Table 4-1. Interaction of Form and Cntby
The default value for Cntby is 1. The current
selection is indicated by an asterisk. The
Cntby function only affects the value seen on
the display. Setpoints, current outputs, and
serial outputs are unaffected by Cntby.
Follow this procedure to modify Cntby.
