Operation

Operation
In addition to the distance, the laser range finder can be used to determine the surface and
volume. It is also possible to perform indirect measurements; to add and subtract measured
values; save measured values; determine the minimum and maximum values and to alter the
reference point of the measurement depending on circumstances.
It is fitted with a spirit level to ensure level installation and a ¼ inch thread for a tripod stand, in or-
der to ensure the greatest level of measurement exactness over longer distances (up to 60 m).

Switching on and off

Press the (G) button to switch on. After approx. one second, the dis-
play shows measurement readiness as shown in the adjacent figure.
The flashing symbol indicates that the target laser has been
switched on.
Range finding is automatically pre-selected after activation.
The target laser is automatically switched off after approx. 30 seconds without measurements;
this saves energy.
To switch off the instrument, depress and hold the (F) button approx. one second.
The instrument switches off automatically after approx. three minutes without a measurement
having been performed.

Reference point

Depending on the measurement requirements, up to three different target points can be se-
lected with the (C) button to serve as the reference point for the measured distance.
Leading edge: Rear edge: Angle "corner":
To measure from a corner, select the reference point "corner" and open the target bracket on
the rear edge of the instrument. Apply the instrument with the target bracket in the corner in
order to measure the range from the targeted point.
