The previous minimal and maximal values are deleted by pressing the
button for clearing the internal memory 4.
Pressing the measuring button 2 ends the continuous measurement. The
last measured value is displayed in the result line c. Pressing the measuring
button 2 again restarts a continuous measuring run.
Continuous measurement automatically switches off after 5 min. The last
measured value remains indicated in the result line c.
Note: Indirect distance measurement is always less accurate than direct
distance measurement. Depending on application, greater measuring
errors are possible than with direct distance measurement. To improve the
measuring accuracy, we recommend using a tripod (accessory).
The indirect distance measurement is used to measure distances that
cannot be measured directly because an obstacle would obstruct the
laser beam or no target surface is available as a reflector. This measuring
procedure can only be used in vertical direction. Any deviation in horizontal
direction leads to measuring errors.
The laser beam remains switched on between the individual measurements.
For indirect length measurements, three measuring modes are available.
Each measuring mode can be used for determining different distances.
a) Indirect height measurement (see figure C)
Press the function-mode button 8 until the indication for indirect height
measurement appears
Pay attention that the measuring tool is positioned at the same height
as the bottom measuring point. Now, tilt the measuring tool around
the measurement reference and measure distance "1" as for a length
measurement.
The current measuring value is displayed in the result
line c. The maximal ("max") and the minimal ("min")
measuring value are displayed in the measured-value
lines a. It is always overwritten, when the current length
measurement value is less than the present minimal or
larger than the present maximal value.
