3. EC Declaration of Conformity
This is to certify that Snap-on Model EEDM575D con-
forms to the protection requirements of the council direc-
tive 89/336/EEC, in the approximation of laws of the
member states relating to Electromagnetic compatibility
and 73/23/EEC. The Low Voltage Directive by application
of the following standards:
EN 61326 1997+A1+A2:2001
EN 50082-1 1992 Immunity Standard
EN 61010-1 2001 Safety Standard
EN 61010-2-32 2001 Safety Standard
EN 61010-2-032 1995 Safety Standard
To ensure conformity with these standard, this
instrument must be operated in accordance
with the instructions and specifications given in
this manual.
CAU ION: Even though this instrument complies
with the immunity standards, it’ s accuracy can be
affected by strong radio emissions not covered in
the above standards. Sources such as hand-held
radio transceivers, radio and V transmitters, vehi -
cle radios and cellular phones generate electro -
magnetic radiation that could be induced into the
test leads of this instrument. Care should be taken
to avoid such situations or alternatively, check to
make sure that the instrument is not being influ -
ence by these emissions.
CAU ION: Please follow manufacturers test pro -
cedures whenever possible. Do not attempt to
measure unknown voltages or components until a
complete understanding of the circuit is obtained.

B. SAFETY CONSIDERATIONS
WARNING:Please follow manufacturers test pro-
cedures whenever possible. Do not attempt to mea-
sure unknown voltages or components until a com-
plete understanding of the circuit is obtained.
Read instructions before operating:
Be sure these instructions accompany the tool when
passed from one user to a new or inexperienced user.
Equipment is used in a manner not specified by the
manufacturer, the protection provided by the equip-
ment may be impaired.
GENERAL GUIDELINES
ALWAYS
• Test the EEDM575D before using it to make sure it is
operating properly.
• nspect the test leads before using to make sure there are
no breaks or shorts.
• Double check all connections before testing.
• Have someone check on you periodically if
working alone.
• Have a complete understanding of the circuit
being measured.
• Disconnect power to circuit, then connect test leads to
the EEDM575D, then to circuit being measured.
NEVER
• Attempt to measure unknown high voltages.
• Attempt to measure DC microamps with the meter in
parallel to the circuit.
• Connect the test leads to a live circuit before
setting up the instrument.
• Touch any exposed metal part of the
test lead assembly.
