WORKING ADVICE

General Information
The reception lens 12 and the laser beam outlet 11 must not be covered when taking a measurement.
The measuring tool must not be moved while taking a measurement (with the exception of the continuous measurement
function). Therefore, place the measuring tool, as far as this is possible, against or on the measuring points.
Measurement takes place at the center of the laser beam, even when target surfaces are sighted at an incline.
Influence Effects on the Measuring Range
The measuring range depends upon the light conditions and the reflection properties of the target surface. For improved
visibility of the laser beam when working outdoors and when the sunlight is intense, use the laser viewing glasses
(accessory not included) and the laser target plate (accessory not included), or shade off the target surface.
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be excluded when measuring on different surfaces. Included here
are:
- transparent surfaces (e. g., glass, water),
- reflecting surfaces (e.g., polished metal, glass),
- porous surfaces (e.g. insulation materials),
- structured surfaces (e.g., roughcast, natural stone).
If required, use the laser target plate (accessory not included) on these surfaces.
Also, air layers with varying temperatures or indirectly received reflections can affect the measured value.
MESSAGE CODE
Message code Possible Cause
Err10 Battery too low
Err15 Out of range
Err16 Received signal too weak
Err18 Background brightness too high
Err26 Out of display
Accuracy Check of the Measuring Tool
The accuracy of the measuring tool can be checked as follows:
-Select a permanently unchangeable measuring section with a length of approx. 3 to 10 meters; 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 after another.
The deviation of the individual measurements from the mean value must not exceed ±2mm (max.).Log the
measurements, so that you can compare their accuracy at a later point of time.

MAINTENANCE AND SERVICE

Store and transport the measuring tool only in the supplied package. Keep the measuring tool clean at all times.
Do not immerse the measuring tool in water or other fluids.
Wipe off debris using a moist and soft cloth. Do not use any cleaning agents or solvents.
Maintain the reception lens 12 in particular, with the same care as required for eye glasses or the lens of a camera.
. When switching off the measuring tool, the value in the memory is retained
Remedy
Change batteries
Measure target within the range
Use light color target; Hold quick measure more steady
Use dark colored target
so that is indicated in the display.
