2.3 Moving / positioning the height measuring instrument
By pressing the switch for the air bearing a ca. 9 µm high air cushion
inflates underneath the height measuring instrument, enabling the
operator to comfortably move and without jolting the height
measuring instrument into the desired position upon the base plate.
As soon as the switch for the air bearing is released, the air cushion
will deflate and the height measuring instrument will once again
stand firmly upon the base plate.

The pump for the air bearings should not be used continuously. This
pump is only to be employed as a short-term pump to position / move
the height measuring instrument.
