Safe choice of accessories and testing electrodes
In order to provide for a safe and trouble-free testing it is
compulsory to consider all testing conditions and procedures
before choosing the necessary accessories and the right size
and type of the testing electrodes. The user is responsible for the
right choice of accessories and electrode size, for their proper
use as well as their related maintenance.
Functional Test:
Before beginning with the tests, establish contact between the
testing electrodes and the grounding terminal with the test
voltage enabled. When approaching the grounding terminal,
sparking should be observed. The distance at which sparking
occurs depends on the adjusted magnitude of the test voltage.
Alternatively, the functional verification can be performed on a
test pore. At the moment of the flashover the acoustic alarm
must be audible and the LED on the membrane-switch front
panel must be lit in red.
