4.0 Description
The KD1E range of neon and digital potential indicators
are comprised of the following features:-
4.1 The units consist of an element manufactured
from a high quality PVC grade 7 tube that conforms
to BS3506. The tube supports and isolates a chain
of high value internal resistors.
4.2 The total encapsulation of the load element
prevents any internal tracking or leakage.
4.3 A handguard in the form of a fl ange (neon type) or
display housing (digital type) on the handle section
of the unit prevents the operators’ hands from
straying towards the high voltage ends of the
potential indicator.
4.4 Type neon indicator. The neon indicator is
enclosed in a fl exible transparent sleeve that
prevents the transmission of any outside shocks to
the glass envelope of the neon.
4.5 Type neon indicator. The neon’s are visible
through a viewing window located in the PVC tube
above the handguard.
4.6 Type digital indicator. The voltage display is
incorporated into the handguard housing.
4.7 An external domed or fl at type (model specifi c)
ensures a positive contact with any terminal
required to be tested.
4.8 An insulated earth cable is connected to the
potential indicator through the handle section. The
earth cable is a permanent connection on neon
indicator models but is detachable on digital
models. This earth cable is fi tted with a suitable
clamp that allows the operator to reference the
potential indicator to a suitable earth.
4.9 Labels present on the equipment and accessories
are there to ensure safe use of the equipment.
