IMPORTANT SAFETY WARNINGS

WARNING

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.

• 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: arching, 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 for trade professionals who are familiar with the
hazards of their trade. 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.

A. Clamp: Measure inductive AC/DC current. Opens to 1.25” (31.7mm).
B. Conductor Alignment Marks: Use to aid the visual alignment of a

conductor when measuring inductive amperage. Greatest accuracy
is achieved when the conductor inside the clamp is centered at the
intersection of these marks.
C. Wire Separation Tab/ NCV sensor: Use to isolate an individual wire from
a bundle for testing. NCV sensor detects live voltage.

D. Test Lead Holder
E. Worklight: Lights clamp area in dark work environments.
F. Category Max Indicator: Maximum CAT Rating for clamp jaw.
G. Hand Guide: Used as a point of reference for the operator’s safety.
H. Clamp Lever: Opens and closes current clamp jaw.

NOTE: The clamp uses a high-tension spring to close the jaw. Do not
allow fingers or objects to become pinched in the base as the jaws close.

I. NCV Alert Light: Indicates voltage when in NCV (Non Contact Voltage)
mode and High Voltage alert.
J. Hold/Worklight/ Back light Button:

• Press to hold the reading on the display. Press again to return to live
reading.

• Press and hold to turn on Worklight and Back light. Press and hold
again to turn off.

• Worklight and Backlight turn off after 60 seconds.

K. NCV Button: Press and hold for Non-Contact voltage detection mode.
L. AC/DC Amps/ Microamps Button:

• Press to enter AC/DC Microamps (μA) mode; (AC/DC microamp
lower display).

• Press and hold to enter AC/DC Amps mode; (AC/DC Amps upper display).
M. Temperature Button:

• Press to enter temperature mode for T1 (upper temperature input jack).

• Press again to enter temperature mode for T2 (lower temperature input
jack).

• Press again to enter temperature differential mode (T1-T2).

• Press and hold to change temperature scale.
