Protective measures against electrostatic discharge
NOTICE
Observe grounding measures
When working with electrostatic sensitive devices, make sure that the person, the
workplace and the packaging are properly grounded. This helps to avoid electrostatic
charging.
As a rule, only touch the ESD if this is unavoidable, for example for maintenance. When you
touch modules, make sure that you do not touch the pins on the modules or the PCB tracks.
In this way, the discharged energy cannot reach and damage the sensitive devices.
Discharge electrostatic electricity from your body if you are performing measurements on an
ESD. Do so by touching grounded metallic parts.
Always use grounded measuring instruments.
