8. Checking the measuring tool
8.1 Accuracy check
To prevent incorrect measurements, the accuracy
must be checked at regular intervals, e.g. before you
start work, or aer hard knocks or major changes in
temperature.
Step 1:
Switch on the electronic spirit level. Use the vial to accura-
tely align the unit to a wall, for example, until
the vial bubble is in the middle between the vial rings.
Step 2:
Wait 10 seconds. If the value displayed is > 0.05°,
the electronic spirit level must be recalibrated.
If mainly used for vertical measurements, the accuracy
check can also be undertaken with the vertical vial.
0° - 0.05° = OK
> 0.05° CAL.
