Chapter 4

Defining Formulas

4–13

Using a sub-code: The operands can be defined so as to provide any of a

number of different types of results data. You do this by including a

sub-code – a decimal point and a number (refer to Table 4.C, page 4–14, for

the definitions of the valid sub-codes).

For example, to specify the pass/fail results from gage 5, in the example

above, you would enter the operand

GAGE5.2:

• Pick G on the formula entry keyboard – this will initially display the

operand

GAGE0 in the formula display area:

= ? GAGE0

Formula:

• Pick 5, then “.” (decimal point), then 2 – this will change the operand to

GAGE5.2.

= GAGE5.2

Formula:

You can see in Table 4.C, page 4–14, that the “.2” sub-code definition is

“Pass/fail condition for fault range (1 = pass, 0 = fail).” During inspections, then,

if gage 5 were to fail, the value 0 would be entered for the

Gage5.2

operand. Conversely, if gage 5 passes, the value of 1 is entered.

Listing operands: Some operators require that you enter one or more

operands in a parenthetical list following the operator. In these cases, when

you pick the operator, the “open” parenthesis is displayed. After you list the

operands (separated by commas), you then enter the “close” parenthesis.

For example, to average the results from gages 1 and 2, enter the formula:

AVG( GAGE1, GAGE2)

• Pick the AVG key on the formula entry keyboard (located on the

secondary key set). The formula keyboard display shows:

= AVG( ?

Formula:

• Pick G (on the initial key set), then 1, then “,” (comma), then G, then 2.

= AVG( GAGE1, GAGE2 ?

Formula:

• Pick “ ) ” (close parenthesis) on the secondary key set. The formula is

now correct in syntax at this point; the “?” disappears.

1 2 ... 23 24 25 26 27 28 29 30 31 32 33 ... 88 89
