Read entire Safety Notes section regarding potential hazards and proper
instructions before using this meter. 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
To ensure safe operation and service of the tester, follow these instructions.
Failure to observe these warnings can result in severe injury or death.
WARNING
• Before each use, verify meter operation by measuring a known voltage or
current.
• Never use the meter on a circuit with voltages that exceed the category
based rating of this meter.
• Do not use this meter during electrical storms or in wet weather.
• Do not use the meter or test leads if they appear damaged.
• Ensure meter leads are fully seated and keep fingers away from the metal
probe contact when making measurements. Always grip the leads behind
the finger guards molded into the probe. For information on test lead shields
instructions on page 19.
• Do not open the meter to replace batteries while the probes are connected.
• Use caution when working with voltages above 60 DC or 25 AC RMS. Such
voltages pose shock hazards.
• To avoid false readings that can lead to electrical shock, replace batteries if
a low battery indicator appears.
• Unless measuring voltage or current, shut off and lockout power before
measuring resistance or capacitance.
• Always adhere to national and local safety codes. Use proper personal
protective equipment (PPE) to prevent shock and arc blast injury where
hazardous live conductors are exposed.
• 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 the circuit.
• In the event of electrical shock, ALWAYS bring the victim to the emergency
room for evaluation, regardless of victim’s apparent recovery. Electrical
shock can cause unstable heart rhythms that may need medical attention.
• If any of the following occur during testing, turn off the power source to the
circuit being tested: arcing, flame, smoke, extreme heat, smell of burning
materials or discoloration or melting of components.
WARNING
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 meter to the desired function and range; connect the test leads to
the meter first, then connect to the circuit under test. Reapply power. If an
erroneous reading is observed, disconnect power immediately and recheck all
settings and connections.
WARNING
This meter is designed to provide HVAC/R technicians with the capabilities they
need to diagnose and repair HVAC/R system. Observe all recommended
safety procedures that include proper lockout utilization and use of personal
protective equipment that includes safety glasses, gloves and flame resistant
clothing.

• Ensure the test lead shield is pressed firmly in place. Failure to use the CAT
IV shield increases arc-flash risk.
CAT II Measurement Locations
• CAT IV shields may be removed for CAT II locations. This will allow testing
on recessed conductors such as standard wall outlets. Take care not to lose
the shields.
WARNING: Test Lead category protections apply only to test leads and
should not be confused with the meter’s specific CAT rating. Observe the
maximum category protection indicated on the meter the test leads are
plugged into.
CAUTION: If the test leads need to be replaced, you must use a new one
which should meet EN 61010-031 standard, rated CATIII 1000V or better.
NOTE: DL599 works with UEi ATL58 test leads, ABP3 back probes and AAC3
alligator clips.
ABP3 Back Probes screw-on to test leads, after removing CATIV shields from
test leads. Back Probes come with covers on probe tips.
