Support Arms
If DIPLODE coil-field electrodes are to be used, a support is required; 2 support arms are
required when using capacitor field electrodes according to Schliephake .
In general, support arms which have only one joint close to the electrode are used - apart from
the double joint where the support arm is fixed.
For applications on high treatment couches or for other special treatment situations, flexible arms
(Fig. 4) with an additional lockable joint
(18)
in the middle of the arm can be used. These arms
are available for right and left operation.
Both types of support arm can be adjusted by means of a fixing knob
(19)
axial displacement
(20)
and rotatory displacement
(21)
.
The connecting cables and most electrodes are secured to the support arm head by means of plug
and socket connections. The large electrodes hole
(22)
accepts the electrodes which are locked in
position by a spring pin locking fixture.
To do this, move the sliders
(23)
on each side perpendicular to the hole so that the locking pin
(24)
does not prevent insertion of the electrodes.
Insert the adjuster pin of the Schliephake electrode into the hole
(25)
and plug socket end of the
electrode cable into the pin socket
(26)
underneath.

Applicators and applicator cables
Coil as well as capacitor-field applicators can be used with the
ULTRATHERM 908i
(see also
paragraph 7, Accessories).
2.4.1
Capacitor-field applicators
(distance applicators according to „Schliephake")
Three pairs of different diameters are available. The capacitor-field electrode consists of 2 caps
(27/28)
, screwed together with enclose an axially movable metal plate with shaft (the actual
electrode c). An adjuster pin
(30)
on the shaft enables the plate electrode spacing to be adjusted
in a defined manner.
The smaller cap
(28)
is fitted with a slotted bush
(31)
with an external thread with which the
metal plate shaft can be guided and by means of which the locking nut
(32)
can be secured. The
locking nut has 4 holes
(33)
around its periphery and a guide groove (
34
). The locking pin of the
support arm must engage in one of the 4 holes. The locking nut is slotted on one side
(35)
, so that
the entire electrode can be held by spring force in the support-arm head.
When the locking pin of the support arm is engaged, the electrode is disengaged by twisting the
two caps anticlockwise
(36)
. The desired electrode spacing can be axially adjusted
(38)
.
The electrode setting can then be secured by twisting the two caps clockwise
(37).
