B. SAFETY CONSIDERATIONS
WARNING!: Please follow manufacturers test
procedures whenever possible. Do not attempt to
measure unknown voltages or components until a
complete understanding of the circuit is obtained.
GENERAL GUIDELINES
ALWAYS
• Test the DMM 196 before using to make sure it is
operating property.
• Inspect 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 under test.
• Disconnect power to circuit, and then connect test leads to
the DMM 196, and then to circuit being measured.
NEVER
• Attempt to measure unknown high voltage.
• Attempt to measure current with the meter in parallel to
the circuit.
• Connect to the test leads to a live circuit before setting up
the instrument.
• Touch any exposed metal part of the test lead assembly.

3. EC Declaration of Conformity
This is to certify that model DMM 196 conforms to the
protection requirement of the council directive 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 50081-1 1992 Emissions standard
EN 50082-1 1992 Immunity standard
EN 61010-1 1993 Safety standard
EN 61010-2-031 1995 Safety standard
To ensure conformity with these standards, this instruction
must be operated in accordance with the instruction and
specifications given in this manual.
CAUTION:
Even though this instrument complies with the
immunity standards, the accuracy can be affected by
strong radio emissions not covered in the above
standards. Sources such as hand held radio
transceivers, radio and TV transmitters, vehicle
radios and cellular phones generate electromagnetic
radiation that could be induced into the test leads of
the instrument. Care should be taken to avoid such
situations or alternatively, check to make sure that
the instrument is not being influenced by these
emissions.
