electronic components or impair their operability. Use a workplace with a grounded work-
ing surface purposely built for electrostatically sensitive devices!
• If you cannot guarantee that the dielectric strength of the measuring device can be main-
tained during the following steps, then an appropriate inspection test must be carried out
