• 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
• Read the safety precautions associated with the equipment being
tested and seek assistance or advice when performing
unfamiliar tasks.
• Keep your fingers away from the test lead metal probe contacts
and bus-bars when making measurements. Always grip the
instrument and test-leads behind the hand guards (molded into
the probes).
• 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.

C o n t rols and Indicators
1.
C l a m p :
Used to measure inductive AC and DC current.
Opens to 1 1/2” (40 mm).
CAUTION!
The clamp uses a high-tension spring to close the jaw.
DO NOT
allow
fingers or objects to become pinched in the base as jaw closes.
2.
Conductor Alignment Marks:
Used to aid in the visual
alignment of a conductor when measuring inductive ampera g e .
Greatest accura cy is achieved when the conductor inside the clamp
is centered at the intersection of these marks.
3.
Hand Guard:
Used as a point of reference for the operator’s safety.
WARNING!
Always keep your hands and fingers behind the hand guards when
measuring current on exposed conductors. Contact may result
in serious safety.
Introduction
The DL49 is a hand-held, battery powered, digital multimeter with clamp-
on current measuring ca p a b i l i ty. This instrument is ideal for anyone that
needs to make quick, accurate measurements of voltage, resistance, and
AC or DC inductive ampera g e .
Features include
• UL listed 3111-1
• Six measurement functions
1. AC inductive amps (to 400 amps)
2. DC inductive amps (to 400 amps)
3. AC Volts
4. DC Volts
5. Ohms
6. Continuity (with audible alert)
• Autoranging
• AC amperage peak-hold
• Data hold for volt, ohm, and amperage functions
• Low battery indicator
• Auto continuity
• Auto power off
• Rugged construction
• Surge protection
• Compact size for easy access to tight areas
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!
Exceeding the specified limits of this meter is dangerous and can
expose the user to serious or possibly fatal injury.
•
DO NOT
attempt to measure any voltage that exceeds 600 volts
with this meter - UEi offers numerous alternatives for measuring
high voltage and current
• Voltages above 60 volts DC or 25 volts AC may constitute a
serious shock hazard
•
DO NOT
attempt to use this meter if either the meter or the test
leads have been damaged. Send unit in for repair by a qualified
repair facility
• Test leads must be fully inserted prior to taking measurements
• 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
• When measuring high voltage, disconnect the power source before
making test lead connections. Connect the test leads to the meter
first then to the circuit under test. Reapply power
