It is important that printed circuit boards and integrated circuits are handled only when
adequate antistatic precautions have been taken to prevent possible equipment damage.
The OCX 8800 is designed for industrial application. Treat each component of the system
with care to avoid physical damage. The probe may contain components made from
ceramics, which are susceptible to shock when mishandled.
