4.12. Distance
measurement with thresholds
The instrument measures distance continuously by
fixing two thresholds (a) and (b) in order to precisely
define the position of objects along a radial line
1. With the instrument in stand-by, press the
key to
select the type of reference (see § 4.2)
2. Press and hold the
key for 2 seconds to enter
the measuring section with dimensions. A flashing
indication of the size (a) appears on the display
3. Use the
or
keys to set the value of size (a)
between 5cm and 60m. Keep the keys pressed to
carry out a quick setting of the values. Confirm the
value of size (a) with key
. A flashing indication of
the size (b) appears on the display
4. Use the
or
keys to set the value of size (b)
between 5cm and 60m. Keep the keys pressed to
carry out a quick setting of the values. Confirm the
value of size (b) with key
. A flashing indication of
the dimension (a) appears on the display
5. Press the
key or the side MEAS key to
measure. The value of distance in real time is shown
on the resulting display
6. Slowly move the instrument along the radial line,
observing the measured value (see Fig. 13). The
instrument shows the arrows
or
to indicate the
direction in which to proceed and starts sounding at
a distance of 0,1m from the thresholds (a) and (b)
fixed, giving out a continuous sound when threshold
is reached. Measurement has a duration of approx.
1 minute and may be stopped by pressing the
or
key
