2.1 Notes Regarding the High-Voltage Test
(only Feature F02 or SECULIFE ST
HV)
The KS13 cable set, or similar cable sets, may not be used for the high-voltage 
test. The high-voltage test may only be performed directly via the test socket!
Attention!
!
Do not hold the device under test in your hand during testing, 
especially when testing safety class II devices. 
Make sure that the device under test does not make contact 
with any equipment or persons during testing.
Liability Exclusion
In the event of sparkover, PCs operated in proximity to the test instrument may 
“crash” resulting in data loss. All data and programs should be suitably backed up 
before high-voltage testing is performed, and computers should be shut down if 
necessary. A crash may occur even if no RS 232 connection has been established.
The manufacturer of the test instrument assumes no liability for direct or 
consequential damage to computers, peripherals or data which occurs 
during high-voltage testing.
The manufacturer assumes no liability for defects at the device under test 
which result from high-voltage testing. As a rule, defects can only occur at 
devices under test which are not in compliance with applicable standards, 
which were previously damaged or which have been improperly repaired, 
because high-voltage testing is required for type and routine testing by 
IEC 61010-1/EN 61010-1 / VDE 0411, part 1, as well as EN 60335, 
EN 60601 and EN 60950.
