4. Extension bars
Extension bars can be supplied in the following forms:
With electrode clamping device (Fig. 4.3.b
) and without electrode
clamping device (Fig. 4.3.b
).
In lengths of 500 mm and 1000 mm.
There is
NO PROTECTION
against flash-overs, neither in
the area of the screwed section on the handle of the
ISOTEST
®
unit not in the area of the screwed section of the
extension bar.
If for technical reasons it is not possible to exclude the
possibility that the tester could come into contact with the
extension bar, then only the hand protection
that is
delimited by two plastic rings is to be used. (See Fig. 4.3.a)
Dampness and dirt on the extension bars and the handle
can cause flash-overs.
The extension bars and the handle of the ISOTEST
®
unit
must therefore be kept completely clean and dry. This
applies in particular if contact by the tester cannot be
excluded completely.
In addition, the extension bars must be checked for
mechanical damage each time before they are used.
In the simplest case, an extension bar is connected with an electrode
clamping device to the handle of the ISOTEST
®
unit (Fig. 4.3.a). When
doing this, it is necessary to ensure that the plastic tube at the end of the
extension bar is firmly attached to the plastic nut of the handle. A locator
tube
must be screwed into the extension bar.
