TERMS AND CONDITIONS OF WARRANTY
SebaKMT accept responsibility for a claim under warranty brought forward
by a customer for a product sold by SebaKMT under the terms stated
below.
SebaKMT warrant that at the time of delivery SebaKMT products are free
from manufacturing or material defects which might considerably reduce
their value or usability. This warranty does not apply to faults in the
software supplied. During the period of warranty, SebaKMT agree to repair
faulty parts or replace them with new parts or parts as new (with the same
usability and life as new parts) according to their choice.
This warranty does not cover wear parts, lamps, fuses, batteries and
accumulators.
SebaKMT reject all further claims under warranty, in particular those from
consequential damage. Each component and product replaced in
accordance with this warranty becomes the property of SebaKMT.
All warranty claims versus SebaKMT are hereby limited to a period of 12
months from the date of delivery. Each component supplied by SebaKMT
within the context of warranty will also be covered by this warranty for the
remaining period of time but for 90 days at least.
Each measure to remedy a claim under warranty shall exclusively be
carried out by SebaKMT or an authorized service station.
This warranty does not apply to any fault or damage caused by exposing a
product to conditions not in accordance with this specification, by storing,
transporting, or using it improperly, or having it serviced or installed by a
workshop not authorized by SebaKMT. All responsibility is disclaimed for
damage due to wear, will of God, or connection to foreign components.
For damage resulting from a violation of their duty to repair or re-supply
items, SebaKMT can be made liable only in case of severe negligence or
intention. Any liability for slight negligence is disclaimed.
Since some states do not allow the exclusion or limitation of an implied
warranty or of consequential damage, the limitations of liability described
above perhaps may not apply to you.

ELECTROMAGNETIC COMPATIBILITY
OF THE HIGH VOLTAGE TEST SETS T 26/1 A, T 26/1 B
The high voltage test sets T 26/1 A and T 26/1 B comply with the
requirements of EN 55011 concerning conducted emission voltages on the
mains supply.
The requirements concerning radiated electromagnetic fields in accordance
with EN 55011 are fulfilled up to a voltage of 110 kV.
Voltages above 110 kV result in exceedings of the limits in the frequency
range 30 ... 120 MHz. These disturbances are caused by principle of
operation and cannot be prevented by any technical procedure.
During operation of the equipment an appropriate distance to any
susceptible instrument or installation has to be kept.
