“Adjust Final Addition Aims at Run Time”, and

“Adjust Final Addition Aims - Method 2”

To help reduce the amount of corrective additions and/or for clients who want to solve additions calculations to company specs rather than working aims, Special Option #66 “Adjust Final Addition Aims at Run Time” has been developed.

This option, if activated, permits ABS to automatically change the working aims, either minimum, maximum or both, before calculating the least cost additions. The working aims are adjusted by ABS when:

• The acknowledged prelim chemistry is less than or greater than the company spec; then the working aim is moved to the company spec value;
• The acknowledged prelim chemistry is within the company spec and working aim; then the working aim is moved to the prelim chemistry value.

Assume the following condition:

To validate this feature, activate the Directory Editor program and set Special Option #66 to one of the following:

1. “L-ower” to permit adjustments to the minimum working aim;
2. “U-pper” to permit adjustments to the maximum working aim; or
3. “B-oth” to permit adjustments to both the minimum and maximum working aims.

The TAP program will highlight the aim, if changed, and display the following message on the prelim chemistry screen:

Highlighted Aims have been changed by you, or ABS

The second method to aid in the reduction of corrective additions and/or for clients who want to solve additions calculations to both company specs and working aims is Special Option #69 “Adjust Final Addition Aims - Method 2”.

With Method 2 activated, the working aims are adjusted by ABS when:

• The acknowledged prelim chemistry is within the company spec and the working aim; then the working aim is moved to the company spec value.
• The acknowledged prelim chemistry is outside the company spec; then the working aim is not changed.

This option works in conjunction with Special Option #66. To use this method, set Special Option #66 and #69 to either “YES” or “BOTH”. After these steps have been completed, whenever an additions solution is performed, the TAP program will adjust aims accordingly. Refer to the example below for specific information.

The aims will not be changed if:

• The company specs do not exist for the element, or;
• The company specs are not outside of the working aims, or;
• The working aims are exact.

NOTE: These Special Options are valid for both intermediate and final additions calculations.
