K
eep A
way From Live Circuits
Operating personnel must not remove instrument covers
. Component replacement and internal
adjustments must be made by qualied maintenance personnel. Do not replace components
with the power cable connected. Under certain conditions
, dangerous voltages may exist even
with the power cable removed. T
oavoid injuries
,always disconnect power and discharge
circuits before touching them.

Do not exceed the operating input power, voltage, and current level and signal type
appropriate for the instrument being used, refer to your instrument's operation manual.
Caution
Electrostatic discharge (
esd
)candamage the highly sensitive microcircuits in
your instrument. ESD damage is most likely to occur as the test xtures are
being connected or disconnected. Protect them from ESD damage by wearing a
grounding strap that provides ahigh resistance path to ground. Alternatively
,
ground yourself to discharge any static charge built-up by touching the
outer shell of any grounded instrument chassis before touching the test port
connectors
.
Never touch the test clip contacts
.
Use awork station equipped with an anti-static work surface
.
