heading used in this manual explains hazards that could damage the instrument.
WARNING 1: The power supply/signal conditioner should not be opened by anyone other than qualified service
personnel.
This product is intended for service by qualified personnel who recognize shock hazards and are familiar
with the safety precautions required to avoid injury.

This equipment is designed with user safety in mind; however, the protection provided by the equipment
may be impaired if the equipment is used in a manner not specified by PCB Piezotronics, Inc.
CAUTION 1: Cables can kill your equipment.
High voltage ElectroStatic Discharge (ESD) can damage electrical
devices. Similar to a capacitor, a cable can hold a charge caused by triboelectric transfer, such as that which occurs in
the following:
Laying on and moving across a rug.
Any movement through air.
The action of rolling out a cable.
Contact to a non-grounded person
The solution for product safety: 1) Connect the cables only with the AC power off. 2) Temporarily “short” the end of
the cable before attaching it to any signal input or output.
