5 Safety instructions
This product is conformed to the requirements of the following European Union regulations:
2004/108/EG (EMC Directive) and 2006/95/EG (low-voltage directive).
When using a product from LANGER EMV-Technik GmbH, please observe the following safety
instructions to protect yourself from electric shocks or the risk of injuries.
Read and follow the manual instructions and keep them in a safe place for later consultation. The
device may only be used by personnel who are qualified in the field of EMC and who are able to
work under the influence of disturbance voltages and (electric and magnetic) burst fields.
Observe the operating and safety instructions for all devices used in the set-up.
Never use any damaged or defective devices.
Carry out a visual check before using a measurement set-up with a Langer EMV-Technik
GmbH product. Replace any damaged connecting cables before starting the product.
Never leave a Langer EMV-Technik GmbH product unattended while this is in operation.
The Langer EMV-Technik GmbH product may only be used for its intended purpose. Any
other use is prohibited.
People with pace-makers are not permitted to work with this device.
In principle, the test set-up should always be operated via a filtered power supply.
Attention! Functional near fields and interference emissions may occur when operating
Pulse- and RF generators or in connection with field sources. The user is responsible for
taking measures to protect the correct function of products outside the EMC environment
of the test set-up (in particular against interference).
This can be achieved by:
observing an appropriate safety distance
using shielded or shielding rooms.
Attention! Measuring devices may be destroyed due to the simultaneous use of Pulse- / RF
generators and meas
uring devices, e.g. oscilloscope and spectrum analyzer. It is the user’s
responsibility to prevent damage from these instruments.
Protect measuring devices by:
Preconnection of filters in signal and supply lines
Using shielded lines
Shielding measuring devices
The shielding has to be done with highest care! One gap at a single spot can lead to the loss of the
whole shielding system effect!
The disturbances that are injected into the assemblies can functionally destroy (latch-up)
the device under test if their intensity is too high.
Protect the device under test by:
preconnecting a protective resistor in the IC power supply
increasing the disturbance step by step, stopping when a functional fault occurs
interrupting the power supply to the device under test in the event of a latch- up
Attention! Make sure that internal functional errors are visible from outside. The device
under test may be destroyed due to an increase in the injection intensity if the errors are
not visible outside.
Take the following measures if necessary:
monitoring of representative signals in the device under test
special test software
visible reaction of the device under test to inputs (reaction test of the device under test)
We cannot assume any liability for the destruction of devices under test!
