Measuring
Please make sure that the measurement is confi gured
and set up as described in the previous section,
including the calibration routine.
The measurement surface may be marked to guide
the orientation of the probe during a scan. Tape, or
a thin rigid grid may be helpful. A single-plane laser
device may also be useful to keep the probe on the
measurement plane, as shown in Figure 21.51.
Decide where to begin the scanning, and tap into
the correct surface. Pressing
START/STOP
will
automatically start at the lower-left segment of the
selected surface. Scan the segment, and press
START/STOP
to stop the measurement when the scan
is completed.
HINT: If an obstacle is encountered during a scan,
press the
key. The measurement will be paused.
If desired, some seconds of the measurement may
also be removed by using the cursors on the
displayed time graph, before pressing the key once
more to resume the measurement.
When the measurement is stopped, the Simple View
will be displayed, and the instrument will allow either to
accept the measurement using the
√ key, or discard the
measurement using the key. The measurement may
be reviewed as normal while waiting for accept. The next
section will describe how to review the results in detail.
If Scanning Direction is set to Both, the next press on the
START/STOP
key will start the second measurement
on the same segment. Otherwise, the next segment
will be scanned. The instrument will progress through
the segments one row at the time, from bottom to top,
always starting with the leftmost segment in each row.
Figure 21.52 shows the segment order progress.
