The CEL-4627 Instrument Tripod has been
specifically selected for use with the CEL range of
acoustic instrumentation. It will locate equipment
securely at the heights required by various
measurement standards, including 1 metre outside
a building.

It is suitable for use with the complete
range of CEL Sound Level Meters that have tripod
mounting bushes, also with CEL-594 and CEL-6737
Outdoor Microphone Enclosures, and CEL
Preamplifiers.

A complete CEL-4627 Tripod consists of
the following items.

CEL-4627 Tripod,

CEL-4621 Preamplifier Adaptor,

CEL-3058 Carrying Case,

060108/HB Instructions.
When your tripod is delivered, check that all items on the schedule have been supplied.

The CEL-6690 Extension Pole Set (3 x 70 cm sections) is available for use with the heavier
CEL-525/530 series of preamplifiers, with or without the CEL-594 Outdoor Protection System. Similarly,
the CEL-6737 Outdoor Microphone Protection System can be used with the tripod (refer to
CEL-594/CEL6737 Users Instructions). The CEL-6690, CEL-594, and CEL-6737 must be ordered
separately.

The tripod legs and
centre column are locked and
released by the single large
handle on the knuckle joint. To set
the tripod up, grasp the centre
column with one hand and turn
the handle counter-clockwise to
release the knuckle joint.

Release the knuckle
joint only enough to free the
moving parts without losing some
degree of friction on the joints.
This will enable you to keep
control of the legs and centre
column, otherwise the legs will
be more difficult to control.

Due to the large degree
of freedom of the legs and centre
column it is important to hold the
centre column before releasing
the knuckle joint. As with most
unique designs, a little practise
will develop your own techniques
for using this equipment.

The centre column of the tripod is fitted
with both 1/4" and 3/8" BSW threaded studs and by
rotating the column around the joint either stud can
be used.

The heading figure shows a sound level
meter attached directly to the 1/4" stud. However
when attaching sound level meters with pressed
aluminium cases, care must be taken not to
overtighten them.

Figure 1 shows an arrangement attached
to the 1/4" stud which uses the three sections of the
CEL-6690 Extension Poles Set to position a
microphone 1 m from the outside wall of a building.
Similar arrangements for light weight microphones
and preamplifiers are shown in Figure 2. These use
the CEL-4621 Preamplifier Adaptor (supplied)
attached to the 3/8" stud to allow measurements to
be made in a variety of positions. The preamplifier
clamp can be rotated allowing the microphone to be
pointed in different directions.

The similar outdoor Microphone
Enclosures CEL-594 and CEL-6737 are shown in
Figure 3.The centre column of the tripod should be
rotated so that it is vertical and the pipe sections of
CEL-6690 attached to the 1/4" stud. It is important to
ensure full weather protection by keeping the centre
columns vertical. When using high vertical
extensions such as these on the tripod, it is also
important to ensure that the legs are well extended
to give the tripod maximum stability and that all locks
are secure. If strong winds are anticipated, the tripod
should be secured to the ground by tie lines to
prevent damage to the instrumentation.
