AMETEK CTS
3.5.
Interference to the environment
CAUTION: The AMETEK CTS interferences generators are instruments with a functionally
emission of electromagnetic interference during the test (e.g., ESD, EFT, conducted RF, etc.).
Therefore, a disturbance of the environment cannot be excluded.
The user has an obligation to use a suitable test environment in order to minimize influences to
CAUTION
the environment. This may require a suitable screening or to test in a shielded room.
Next should be considered during the test, that nearby are no disturbers such as (switching
relays or drives with frequency converters etc.) that can influence through their emission the
test.
3.6.
Testing
The generator can be operated locally from the front panel or remotely from the computer.
When it is necessary to observe the EUT during the test, it can be more comfortable to operate locally. The tester
is nearer to the EUT and therefore faster to switch off the test generator in EUT fail condition.
When the computer fails, the Test On button on the generator front or the Fail 1 input must be used for switching
off the test.
3.6.1.
Safety Precautions
The test area must be secured that only authorized test personnel may enter it.
Working alone with high voltages is dangerous.
The high voltages must be switched off when nobody is present.
Neither the EUT nor cables or accessories must be touched during the test.
Make sure all high voltage connections are adequately insulated to prevent accidental contact by you or
neighboring colleagues.
Keep one hand in your pocket when probing high voltage circuits or discharging capacitors. This reduces the peril
to touch the high voltage with both hands.
While working on the EUT, the test procedure should be stopped and the EUT disconnected from the voltage
power supply.
The EUT must be tested within a safety container or within a protected area. In extreme circumstances the EUT
may ignite or explode as a result of internal damage.
3.7.
Danger from EUT
WARNING: The device being tested may become defective and ignite due to the influence of
the applied test signal.
The stored energy inside the test simulator must be considerred. This energy can destroy or
damage the EUT even when the EUT operates under normal conditions.
WARNING
WARNING: Moving parts may move in an unexpected way due to the interference of the
applied signal.
Never approach a test setup that uses actuators or electric motors during the test run!
WARNING
Therefore, the operator shall take the following precautions:
As soon as the EUT ceases to operate as intended, the test shall be stopped immediately.
