10.1.3.3. Use the [

] key to move to the “ SplitErr: ” field. Use the numeric keypad to
enter a number that will be used to determine the maximum amount of error
between the suggested solution and the available class weight placement
combination. The lower this number, the closer the two solutions will match, but
the longer it may take to generate a solution during the solution process. The
analyzer will warn you if the “SplitErr:” value is greater than 10% of the
difference between the first and second weight. You will have the option to accept
the recommended setting or ignore it.
10.1.3.4. Use the [

] key to move to the “ Num Wts: ” (number of weights) field. Use the
numeric keypad to enter a number corresponding to the total number of different
weights in this class weight set.
10.1.3.5. Use the [

] key to move to the “ Placement ” field. Use the [

] key to select
from “Continuous” or “Spread”. Selecting “Continuous” tells the analyzer to
match the suggested solution as closely as possible while keeping the installed
weights in consecutive positions. Selecting “Spread” allows the analyzer to insert
empty weight positions between weights, as needed, in an attempt to match the
suggested solution.
10.1.3.6. Use the [

] key to move to the “ Add/Remove ” field. The only selection in this
field is “Remove then Add”. You cannot edit this selection at this time.
10.1.3.7. Use the [

] key to move to the “ Name ” field. Use the keypad to enter a name or
part number to identify each weight in the class weight set.
10.1.3.8. Use the [

] key to move to the “ Wt ” (weight) field. This field defines the exact
weight of the individual class weights in the adjacent “Name” field. The unit of
measure is that which you defined in paragraph 10.1.1.9 above. Typically, the
first entry in this table will be a Null weight. A Null weight is one that may be
used to occupy a position when an actual balance weight is not required. It may
also be the smallest available weight in the class weight set or have a weight value
of 0. Normally, if this weight is required to occupy each location not containing a
trim balance weight, its weight value should be 0.
10.1.3.9. Use the [

] key to move to the “ Span ” field. This field defines the number of
positions or weight mounting locations that will be occupied by this class weight.
10.1.3.10. Complete a Name, Wt, and Span field for each of the available fields until the
chart is filled. If you find that you have specified too few or too many class
weights, use the [

] key to place the cursor in the “Num Wts:” field and adjust the
number accordingly. The number of available fields will be changed per this
