Guidance and manufacturer’s declaration – electromagnetic immunity
The Solar Blue measurement system is intended for use in the electromagnetic
environment specified below. The customer or the user of the Solar Blue
measurement system should assure that it is used in such an environment.
When the Solar Blue system is exposed to electromagnetic (EM) disturbances,
the system may show abnormal behavior. For instance, the measured traces
may be become obscured, the software may crash or, in case of very high level
transient voltage events like for instance ESD, parts of the system may even
become defective.
