4.2 Using Level to Calibrate Height Plane
To ensure the accuracy of the measurement it is important
that the calibration of the height plane with the help of the
level is conducted correctly. For this reason follow the
following description carefully.
1.
Select a calibration point in accordance with the data
sheet.
2.
Turn the level so that the adjustable brass knob is
exposed and so that the level is in a straight line with
the measuring arm.
3.
Check the data sheet for the appropriate height
calibration reading. Take a suitable height calibration
rod and adaptor and push it into the socket on top of
the electronic measuring head. A twist-lock action will
secure the rod at the desired height.
4.
Take the measuring arm with magnetic attachment
connected and attach the magnet in the selected
mounting position making sure that the attachment is
firmly seated and that there is no play.
5.
Pull out and adjust the measuring tool so that the
measuring adaptor (socket) fits the calibration point.
6.
Now adjust the level by means of the adjusting knob so
that the bubble is exactly in the center, and between
the markings on the level.
