9.2 Setting warning limits
If tolerance limits are breached, the workpiece
in question must either be reworked or, if unus-
able, scrapped. To avoid this and to quickly iden-
tify trends, warning limits can be set prior to the
tolerance limits being reached. Although work-
pieces that breach these warning limits are still
usable, the repeated and successive breaching of
these limits indicates that the production process
must be amended to prevent items produced at
a later stage from breaching tolerance limits.
1. Press the MENU key. The catalog of func-
tions and parameters item “FEATURE (1)” is
displayed.
2. Press the MENU key again. “FACTOR (1.1)” is
displayed.
3. Use the DATA and MASTER keys to select
“TOLERNCE (1.4)”.
4. Press the MENU key. “COLOR (1.4.1)” is dis-
played.
5. Use the MASTER and DATA keys to select
“WARN. + (1.4.4)”.
6. Press the MENU key. The current value of
the upper warning limit is displayed under
“WARN. +” with a flashing algebraic sign.
7. Change the algebraic sign and numerical
value of the upper warning limit as required
(see section “Changing numerical values for
parameter settings” in Chapter 0).
8. Once the algebraic sign and numerical value
have been set as required, press the START
key. This terminates the process and the set
value flashes.
9. Press the START key again to adopt the
flashing value as the current setting. The dis-
play then returns to the catalog of functions
and parameters item “WARN. + (1.4.4)”.
If at this point either the MASTER or DATA
key is pressed instead of START, the display
returns to the numerical input stage (cf. point
7). The indicated numerical value can be
changed again.
10. Press the MASTER key. “WARN. – (1.4.5)” is
displayed.
11. Press the MENU key. The current value of
the lower warning limit is displayed under
“WARN. –” with a flashing algebraic sign.
