ACCORDING to European standards,
openly operated measuring and testing
equipment has to be checked
regularly. Therefore, spark testers are
tested with regard to the accuracy of
the supplied high-voltage, the short
circuit current and function (sensitivity).
The Sikora spark tester Spark 6030 HF
offers (optionally) a three-step self-test
and calibration system including the
Sikora App for mobile monitoring and
analysis of the measuring results. As
each test probe has to be calibrated,
the testing module has to be controlled
regularly as well.
To support this process, Sikora
developed the module of the Spark
6030 HF further. New is the
easy-to-change module that combines
all testing functions and which can
easily be exchanged from an additional
opening in the housing of the Spark
6030 HF.
In order to meet the requirements of
the ISO 9001 standards, Sikora
recommends a yearly calibration of the
spark tester by simply exchanging the
test module.
Due to the fact that all functions are
directly mounted at the module, the
complete module is exchanged for
calibration. Therefore, a submission of
the complete device to Sikora as well
as the assignment of a service
engineer is not necessary.
As for the previous version of the
module, the sensitivity and short
circuit current tests are generated.
For the sensitivity test, 20 discharges
are simulated in 20 seconds. All of
these discharges have to be
completely detected by the spark
tester.
For the short circuit current test, an
error caused by the contact of a user
and the bead chain electrode during
the operation is simulated. Here, a
defined value must not be exceeded in
order to guarantee the safety of the
user.
The calibration module measures
continuously the accuracy of the
testing voltage. The standard for spark
testers requests an accuracy of ±5 per
cent. The test is successful if this
criterion is met.

Tecno Impianti Srl of Italy is a major
designer and manufacturer of wire
drawing machinery for different sectors
of the wire industry.
Its newest feature is the redesign of its
successful wet wire drawing machine
Model TI-310. The machine is to be
utilised for production of CO2 welding
wire. It will work with a horizontal
spooler and the line will be completed
with coppering tank and dancer.
The drawing machine Model TI-310 is
equipped with 11 wet drawing passes
plus one dry drawing pass at the
entrance, 310mm capstan and major
sized cone-holding shafts.
Tecno Impianti is also present in the
wire drawing machinery sector with
its TR Series of straight-line
multi-pass wire drawing machines,
the MV Series of vertical bull-blocks,
the inverted bull-block Model MVC
and the MO Series of horizontal-axis
wire drawing bull-blocks for CHQ
wire.
All its machines are designed and
manufactured by the company,
equipped with components of leading
brands and can be offered in many
different models and configurations,
with a tailor-made concept.
