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 aer 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.
