may be manually operated by the switch on
the front remote operation is normally required when the device is
operated as a turntable. Typical applications are the measurement of
the directional response of a microphone or a loudspeaker. The table
may be set up to rotate continuously and the angular position may be
logged, or the table may be set up to rotate in small steps.
The torque of the device is limited in order not to harm the user or
devices placed on or around the turntable. Still it can carry
considerable loads in any direction. Note therefore that the loads have
to be balanced around the turning axis. If a large or heavy object is
placed on the table, increase the acceleration time in order to reduce
the torque needed to produce the required acceleration.
The table will not be harmed by blocking its movement. The table
may be turned by hand, even when powered, to obtain a suitable
reference angle.
Since the angle may be controlled very accurately and even specified
as a number of rotations (e.g. specifying 3500° means about 9,7
revolutions)

applications. Sketches of applications for horizontal and vertical
movement are shown below.
