General Information
2.1.3 Electrostatic Discharge (ESD) considerations
Important Note: To minimize hazards and ESD risks, maintenance procedures not
requiring power to the analyzer should be performed with power removed.
Delicate internal electronic components can be damaged by static electricity, resulting in
degraded instrument performance or eventual failure.
The manufacturer recommends taking the following steps to prevent ESD damage to
the instrument:
• Before touching any instrument electronic components (such as printed circuit cards
and the components on them) discharge static electricity. This can be accomplished
by touching an earth-grounded metal surface such as the chassis of an instrument,
or a metal conduit or pipe.
• To reduce static build-up, avoid excessive movement. Transport static-sensitive
components in anti-static containers or packaging.
• To discharge static electricity from the body and keep it discharged, wear a wrist
strap connected by a wire to earth ground.
Handle all static-sensitive components in a static-safe area. If possible, use anti-static
floor pads and work bench pads.
2.1.4 Battery safety information
WARNING
An explosion can occur if the internal battery is replaced incorrectly.
Figure 1 shows the label that is displayed on the battery for the safety of the user.
