Review the following safety precautions to avoid injury and prevent damage to
this product or any products connected to it. To avoid potential hazards, use this
product only as specified.
To Avoid Fire or
Personal Injury
Use Proper Power Cord. Use only the power cord specified for this product and
certified for the country of use.
Connect and Disconnect Properly . Connect the probe output to the measurement
instrument before connecting the probe to the circuit under test. Disconnect the
probe input and the probe ground from the circuit under test before disconnecting
the probe from the measurement instrument.
Ground the Product. When operating from AC power, this product is grounded
through the grounding conductor of the power cord. To avoid electric shock, the
grounding conductor must be connected to earth ground. Before making
connections to the input or output terminals of the product, ensure that the
product is properly grounded.
When operating with battery power, this product must still be grounded. To
prevent electric shock, always connect a grounding wire between the ground
terminal on the rear panel and earth ground.
Observe All Terminal Ratings. To avoid fire or shock hazard, observe all ratings
and markings on the product. Consult the product manual for further ratings
information before making connections to the product.
Connect the ground lead of the probe to earth ground only.
Replace Batteries Properly. Replace batteries only with the proper type and rating
specified.

Damage
General Safety Summary
CAUTION. Electrostatic discharge (ESD) can damage components in the
oscilloscope and its accessories. To prevent ESD, observe these precautions
when directed to do so.
Battery Recycling
Use a Ground Strap
. Wear a grounded antistatic wrist strap to discharge the static
voltage from your body while installing or removing sensitive components.
Use a Safe Work Area.Do not use any devices capable of generating or holding a
static charge in the work area where you install or remove sensitive components.
Avoid handling sensitive components in areas that have a floor or bench top
surface capable of generating a static charge.
Handle Components Carefully .
Do not slide sensitive components over any
surface. Do not touch exposed connector pins. Handle sensitive components as
little as possible.
Transport and Store Carefully.
Transport and store sensitive components in a
static-protected bag or container.
