Inaccurate measurements are also possible where the laser is pointed at target surfaces
diagonally.
Layers of air at different temperatures and indirectly received reflections can also influ-
ence the measured value.
Accuracy check of the distance measurement
You can check the accuracy of the measuring tool as follows:
– Choose a measuring section of approx. 3–10 m in length that is permanently un-
changed, the exact length of which is known to you (e.g. room width, door opening).
The measurement should be taken under favourable conditions, i.e. the measuring
section should be indoors with weak backlighting and the target surface for the meas-
urement should be smooth and reflect well.
– Measure the section ten times in succession.
The deviation of the individual measurements from the mean value must not exceed
±4mm over the entire measuring section in favourable conditions. Record the measure-
ments, in order to be able to compare the accuracy later on.
Working with the tripod (accessory)
The use of a tripod is particularly necessary for larger distances. Place the measuring tool
with the 1/4" thread(13) on the quick-release plate of the tripod(19) or a commercially
availablel camera tripod. Tighten it using the locking screw of the quick-release plate.
Set the corresponding reference level for measurement with a tripod by pushing the
[Func] button(7) (the reference level is the thread).
Error message
If a measurement cannot be performed correctly, the "Error" message appears in the dis-
play. Switch the measuring tool off and back on, and start the measurement again.
The measuring tool monitors correct functioning in every measure-
ment. If a defect is detected, the display will indicate only the symbol
shown opposite and the measuring tool switches itself off. In this
case, have the measuring tool checked by an after-sales service agent
for Bosch power tools.
