• Even moderate amounts of current can cause ventricular fibrillation
• Use insulated tools and gloves to avoid electrical shock
• Disconnect wiring from supply voltage before performing
continuity tests
• Disconnect the negative battery terminal when removing and
replacing starters, alternators, and other components that have
direct connections to the battery
Multimeter Safety Precautions
When making resistance measurements, ensure no voltage is present
in the component or wire being tested. When making voltage or
current measurements, ensure you don’t exceed the maximum rating
of the ACM6000.

Introduction
The ACM6000 DC/AC Clamp Meter instrument allows pocket sized
convenience for testing voltage, current flow, resistance, continuity
and temperature.
A voltage measurement does not always provide complete information
about the behavior of a circuit. A current measurement, in addition to
the voltage measurement, provides additional information to help you
make a correct diagnosis.
The instructions, recommendations and illustrations in this manual are
intended the basic information necessary to get you started on the path
to automotive electrical diagnostics.
State-of-the-art electronic test tools are not very effective without under-
standing basic automotive electrical diagnostics and basic electrical cir-
cuits. Training courses are usually available from local schools. For
additional information on domestic field training, contact the
UEI
Automotive Field Training Center at (770) 476 -1431 (8-5 PM, EST)
.
Custom contract training can be provided in your area.
Safety Notes
Before using this meter, read all safety information carefully. In
this manual the word
"WARNING"
is used to indicate conditions
or actions that may pose physical hazards to the user. The word
"CAUTION"
is used to indicate conditions or actions that may
damage this instrument.
WARNING!
Follow appropriate work area safety precautions
Automotive safety
When performing vehicle maintenance, work in a well-ventilated
area - route exhaust gases out of work area. Work in a well-lit
environment. Use supplemental work lights in service area.
•
DO NOT
wear jewelry (rings, watches, etc.) when
working on vehicles
• Wear approved safety eyewear at all times
• Avoid rotating fan blades, drive-belts and pulleys on
running engines
• Beware of electrical shock when working on vehicle wiring and
electrical systems
• Keep open flames and sparks away from batteries, engine fuels
and oils
