10.1.4.2. Use the [

] key to move to the “ Posn Type: ” field. This field will define the
terminology used to refer to the weight locations throughout the balance job. The
choices in this field are <Position>, <Hole> or <Blade>. After you exit this field
the remaining references will change to the selected term. Consequently, the
fields described in these instructions are identified generically as “Position”.
Your screen will display the actual term you selected in this field.
10.1.4.3. Use the [

] key to move to the “ Num Positions: ” (number of weight positions)
field. Use the numeric keypad to enter a number equal to the total number of
positions where balance weights may be attached for this balance plane only.
10.1.4.4. Use the [

] key to move to the “ Num Usable: ” field. Use the numeric keypad to
enter a number that will define the maximum number of positions that can be used
for installing weight on a single run. The number entered is limited to half of the
value in the “Num Positions:” field plus one with a maximum of 24. For example,
in the screenshot above, the number of weight positions is 22 (half of 22 + 1 =
12), the value entered in the “Num Usable:” field will be 12.
10.1.4.5. Use the [

] key to move to the “ Detail Reduce Usable? ” This field will let you
define whether the detail weight holes reduce the number of holes usable for trim
balance. In some cases, the “
Num Usable ” holes, paragraph 10.1.4.4 above, may
be reduced by the presence of detail weights. In this case, enter “Yes” and the
analyzer will reduce the number of available trim balance holes by the number of
holes occupied by detail weights. If this field is set to “No”, the analyzer will not
reduce the number of available trim balance holes by the number of holes already
occupied by detail weights. For example, with this field set to “Yes”, if there are
15 usable holes and four are already filled with detail weights, the analyzer will
only place trim balance weights in 11 holes. With this field set to “No” the
analyzer will be able to place trim weight in all 15 Usable holes. This field is only
available if the “Label Detail Wts:” field in 10.1.1.8 above is set to “Job” or
“Setup”
10.1.4.6. Use the [

] key to move to the “ RivetWt: ” field. Use the numeric keypad to
enter a value for the weight in grams or ounces (as defined in paragraph 10.1.1.9
above) of any attaching hardware used to secure the balance weight to the balance
plane.
10.1.4.7. Use the [

] key to move to the “ Radius ” field. This field will only appear if an
optional balance plane is identified in paragraph 10.1.1.5 above. Use the numeric
keypad to enter a value defining the radius of the weight locations on this balance
plane.
