Accuracy Check of the Distance Measurement
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 metres; its length must be precisely known (e.g. the width of a room or a door
opening). The measurement should be carried out under favourable conditions,
meaning, the measuring distance must be indoors and 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 average value must not exceed
±4 mm over the entire measuring section in favourable conditions. Record the meas-
urements in order to be able to compare the accuracy at a later date.
Working with the Tripod (Accessory)
The use of a tripod is particularly necessary for larger distances. Position the measur-
ing tool with the 1/4" thread 13 onto the quick-change plate of the tripod 19 or a com-
mercially available camera tripod. Tighten the measuring tool with the locking screw
of the quick-change plate.
Set the corresponding reference level for measurement with a tripod by pushing but-
ton 4 (the reference level is the thread).

Error Message

If a measurement cannot be performed correctly, the error message "Error" appears
in the display. 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.
