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

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
