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.
