B.3 Extension Rod
Extension rods 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.
Warning !
There is
NO PROTECTION
against flash-overs, neither in the area of the
screwed section on the handle of the ISOTEST unit nor in the area of the
screwed section of the extension rod.
If for technical reasons it is not possible to exclude the possibility that the
tester could come into contact with the extension rod, then only the hand
protection
that is delimited by two plastic rings is to be used. (See Fig.
4.3.a)
Important !
Dampness and dirt on the extension rods and the handle can cause flash-
overs.
The extension rods 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 rods must be checked for mechanical damage
each time before they are used.
In the simplest case, an extension rod 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 rod is firmly
attached to the plastic nut of the handle. A locator tube
must be screwed into the
extension rod.
