UEi Test Instruments DM5B - Manual (Page 2)

Introduction
The DM5B digital multimeter is a pocket sized, hand held, battery
operated, voltage, current and continuity measurement instrument. It
provides the accuracy and numerous functions typically found in full
sized multimeters.
Features include
• 750 Volts AC & DC
• 5 Amps AC & DC
• Continuity
• Resistance to 30
• Megohms
• Autoranging
• Analog bar-graph
• Data hold
• Fuse protected current ranges
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.
• Always follow industry standard safety practices including protective
clothing, gloves and safety glasses when appropriate
• Do not attempt to measure any voltage that exceeds 1000 volts AC or
DC with this meter.
• Do not attempt to use this meter if either the meter or the test
leads have been damaged. Turn it in for repair at a qualified
repair facility
• Ensure meter leads are fully seated by making a quick continuity
check of the leads prior to making voltage measurements
• Keep your fingers away from the test lead’s metal probe
contacts when making measurements. Always grip the leads behind
the finger guards molded into the probes
• Use a current clamp adapter when measuring current that may
exceed 10 amps. See the accessories in UEi’s full-line ca t a l o g
• Do not open the meter to replace batteries or fuses while the
probes are connected
WARNING!
Exceeding the specified limits of this meter is dangerous and can
expose the user to serious or possibly fatal injury.
• Always turn off power to a circuit (or assembly) under test
before cutting, unsoldering, or breaking the current path -
Even small amounts of current can be dangerous
• Always disconnect the live test lead before disconnecting the
common test lead from a circuit
• In the event of electrical shock, ALWAYS bring the victim to
the emergency room for evaluation, regardless of the victim’s
apparent recovery - Electrical shock can cause an unstable heart
rhythm that may need medical attention
• Higher voltages and currents require greater awareness of
physical safety hazards - Before connecting the test leads; turn
off power to the circuit under test; set the meter to the desired
function and range; connect the test leads to the meter first, then to
the circuit under test. Reapply power
• If any of the following indications occur during testing, turn off
the power source to the circuit under test:
• Arcing
• Flame
• Smoke
• Extreme Heat
• Smell of Burning Materials
• Discoloration or Melting of Components
CAUTION!
Do not attempt to re m ove the meter leads from the circuit under test. The
leads, the meter, or the circuit under test may have degraded to the point
that they no longer provide protection from the voltage and curre n t
applied. If any of these erroneous re a d i n gs are observed, disconnect
power immediately and recheck all settings and connections.
