General Information
The reception lens (15) and the laser beam outlet (16)
must not be covered when taking a measurement.
The laser measure must not be moved while taking a
measurement. Therefore, place the laser measure, as
much as possible, against or on a firm stop or supporting surface.
Influence on the Measuring Range
The measuring range depends on the light conditions
and the reflection properties of the target surface.
Influence on the Measuring Result
Due to physical effects, faulty measurements cannot be
excluded when measuring on different surfaces which
include:
ment. Hold down the function button (2) [Func]. Press
the plus button (6) [
scroll until the highlighted box appears over the icon
. Press the measure button (5) [ ]. Place the laser
measure on a table or surface and measure the grade.
Turn the laser measure 180° and measure the grade
again. The difference of the indicated reading may not
exceed 0.3°. If the deviation is greater, the laser measure must be recalibrated. Select . Follow the directions on the display.
After severe temperature changes or impacts, we recommend to check the accuracy and, if required, to recalibrate the laser measure. After a temperature change,
the laser measure must adjust to the new temperature
before calibrating.
Accuracy Check of the Distance Measurement
The accuracy of the distance measurement can be
checked as follows:
- Select a permanent measuring section with a length
of approx. 10 ft to 33 ft (3 m to 10 m); its length
must be precisely known (e.g. the width of a room
or a door opening). The measuring distance must
be indoors; the target surface for the measurement
must be smooth and reflect well.
- Measure the distance 10 times in a row.
The deviation of the individual measurements from the
mean value must not exceed ± 5/32” (± 4 mm). Log the
measurements so that you can compare their accuracy
at a later point in time.
Working with the Tripod (Accessory)
The tripod is particularly useful for measuring greater
distances. Position the laser measure with 1/4” thread
(14) onto the quick-change plate of a tripod (21).
Tighten the laser measure with the locking screw of the
quick-change plate.
Set the corresponding reference point for the measurement with a tripod by pushing the measuring reference
button (5) and using the plus button (6) [
button (3) [ ] to scroll until the highlighted box appears over the .
If a measurement is not done correctly, the error message “Error” appears in the display. Turn the laser
measure off and on again, and start the measurement
again.
