1. Application
The Prüfball SPB is a two-pole voltage tester in
accordance with EN/IEC 61243-3.
You can use the Prüfball SPB to measure d.c. and a.c.
voltages within the nominal voltage range, specified
on the type plate. Furthermore you can use the
device to determine polarity, phase, phase sequence
and continuity.
Thanks to its high degree of protection (IP 65) the
Prüfball SPB may even be used in rain.

1.1 Intended use

This device is intended for use in applications as
described in the operating instructions only. Thus,
it is imperative to observe the notes on safety and
the technical data in conjunction with the ambient
conditions.
Any other form of usage is not permitted and can
lead to accidents or destruction of the unit.
Any misuse will result in the expiry of all guarantee
and warrantly claims.
2. Safety Precautions
The Prüfball SPB has been approved by VDE test
authorities for application of the VDE GS-symbol.
When used for its intended purpose, the safety of
the operator, as well as that of the instrument, is
assured.
In order to maintain flawless technical safety con-
ditions, and to assure safe use, it is imperative that
you read these operating instructions thoroughly
and carefully before placing your instrument
into service, and that you follow all instructions
contained therein.
Observe the following safety precautions:
 The voltages indicated on the Prüfball SPB are
rated voltages. The voltage tester may only be
used in systems working within these rated
voltage ranges.
 Faultless indication of display values is only
guaranteed between -15° and +45°C.
 Hold the instrument by the handgears only, to
avoid covering the display and not touching the
test electrodes.
 The maximum on-period is 120 s.
