General information
The Prüfball SPB is provided with a thread on both
test electrodes. You may only use original accessories
from the manufacturer, e.g. test probes for overhead
lines, insertion prods, pin prods, adapters etc.
Attention!
The connection between test probe and voltage tester
has to be controlled in each case! Check function at a
known voltage source or by self-test.
Only a perfect mechanical connection ensures safe
contact and thus an unambiguous voltage test.
Safety instructions
Only qualified personnel with appropriate
protective equipment may do these workings.
Observe the minimum object distance to other
plant components that are energized or earthed
and use personal protective equipment as speci-
fied by national accident prevention regulations
(in Germany: DGUV 3 or EN 50110-1).
Hold the instrument by its handles only to avoid
covering the display or touching the extension
probes.
Voltage testers and test probes etc. must be kept
dry and clean.
Voltage testers and test probes etc. may not be
used when they are damaged.
Additional safety instructions
Insertion prod SPB-S20-A
Insertion prods may only be plugged to un-
covered cables into single wires otherwise there
is risk to short circuit.
Insertion tests damage the wire insulation.
Tests may only be performed at test points that
are sealable afterwards, e.g. at junction sleeves.
Pin tip SPB-S70
Secure functioning can only be ensured with
contact positioned in the front. Test points at
the side must be visibly connected (not suitable
for sockets).
