Operating Manual Isotest II T / II RT
1.2
General Characteristics
Both tester series II T with a fixed test high voltage and series II RT(-F) testers with
infinitely variable test high voltage up to 35 kV are characterised by the following
features:
•
Efficient, safe and reliable testing of coatings or sheathings of a wide range of
different types and thicknesses.
•
The possibility of testing all non-conductive and barely conductive materials for
leaks and pores.
•
The extremely short high-voltage pulses ensure that even the smallest pore
(channels) and flaws are reliably detected and indicated.
•
Thanks to the high pulse repetition frequency, testing speeds of up to 250 mm/s
are possible.
•
The test high voltage is set using a sphere gap in accordance with VDE 0433.
•
The constant adaptation of the power supply by the control electronics guaran-
tees a constant output voltage even under widely differing load conditions.
•
Assuming proper use of the tester (see 2.2), residual charges on the test object
can be neglected thanks to the very brief unipolar pulses.
•
Material testing is completely non-destructive. The load on the sheath material is
minimised by the very brief pulses.
•
Thanks to the sturdy design in conjunction with proven technology, the tester is
suitable for use under the arduous working conditions on construction sites.
•
More than 40 years of experience in the field of high-voltage testing are your
guarantee of proven and advanced technology.
