• Slowly raise the lifting table with the glass plate
up to the pins . The handle is in horizontal
position and points forward. The pendulum
must lift up equally with both balls, if not the
pins can be moved slightly in vertical direction.
In the lifted position the pendulum must swing
freely.
• Check the position of scale to the pendulum.
The completely stopped pendulum must point
exactly to the zero marking of the scale. If
not, check the tip of the pendulum. If twisted,
straighten it and position the pendulum with
the lifting table in the lowered position and then
raise it. Repeat this procedure three times to
assure an equal rest.
• Pull out the handle.
• Put the protective cover (mounting see chapter
9) onto the instrument. The case fi ts exactly
onto the edges of the base plate. Eventually fi x
the cover plates in the treads with a suitable
adhesive.
• Insert the handle through the opening in the
cover into the jack underneath the lifting table.
Check the bubble level once more, correct the
leveling if necessary.
The pendulum tester is now ready for operation.
