1, Select "JOG" mode in the "Machine" operating area.
2. Execute the tool change and alignment in the T, S, M window before
performing the measurement.
3. Press the "Meas. tool" softkey.
4. Press the "X" or "Z" softkey, depending on which tool length you want
to measure.
5. Scratch the required edge using the tool.
If you do not wish to keep the tool at the workpiece edge, then press
the "Save position" softkey.
The tool position is saved and the tool can be retracted from the
workpiece. For instance, this can be practical if the workpiece diameter
still has to be subsequently measured.
If the tool can remain at the workpiece edge, then after scratching you
can directly continue with step 7.
6. Enter the position of the workpiece edge in X0 or Z0.
If no value is entered for X0 or Z0, the value is taken from the actual
value display.
7. Press the "Set length" softkey.
The tool length is calculated automatically and entered in the tool list.
Whereby the cutting edge position and tool radius or diameter are
automatically taken into consideration as well.
