Chapter 2
Handling, Storage & Shipping
This chapter addresses procedures for handling electrostatic discharge (ESD) sensitive
equipment, as well as procedures for unpacking, inspecting, and storing of the system.
Caution: This system is an ESD sensitive instrument. Use proper ESD
protective equipment and procedures. Failure to comply with ESD procedures
can result in circuit damage.
ESD Procedures
The instrument contains electronic components that can be damaged from discharges
of static electricity. Ordinarily, handling the circuit boards by their edges will not
damage the circuits.
Caution: Do not touch the circuit board components.
Observe the following when installing, setting up, servicing, troubleshooting or
repairing the instrument:
1. Use an antistatic bag. Most instrument subassemblies ship in a special antistatic
bag. When not installed, keep the assembly in the bag as often as possible.
2. Remove ESD-sensitive subassemblies only under the following conditions:
a. When standing at a designated static-free workstation, or when the bag is
grounded at a field site.
b. After the conductive area of the container has been neutralized.
c. After making firm contact with an antistatic mat and/or firmly gripping a
grounded individual.
3. Personnel handling ESD-sensitive devices should be neutralized to a static-free
workstation by means of a grounding wrist strap connected to the station or to a
good grounding point at the field site.
4. Do not allow clothing to make contact with ESD sensitive devices.
5. Avoid touching edge connectors and components.
6. Avoid partially connecting ESD-sensitive devices. Floating leads can damage these
devices, especially the power supply connector.
7. Ground all test equipment.
8. Avoid static charges during troubleshooting.
