IMPORTANT SAFETY WARNINGS
WARNING
Read entire Safety Notes section regarding potential hazard 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, AL
s apparent recovery. Electrical shock can cause unstable heart rhythms that may need medical attention.
victim’
•
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.
WAYS bring the victim to the emergency room for evaluation, regardless of
.
.
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.

Watt (Power Factor)
Measurement of Active, Apparent and Reactive Power; W,VA, VAr
The current path be measured directly (up to 10A maximum; up to
16A briefly for a maximum of 30 seconds) or with the help of current
transformers or current clamp transformers. The meter automatically
selects the range which allows for the highest possible resolution of the
applied quantities.
NOTE:
If the meter activates a measuring range which is too high during
automatic measuring range selection, this may be due to peak value
monitoring. Check the crest factor of the respective signal in Volts AC or
DC or Amps AC or DC.
Significance of the Power Factor:
±1: no phase shifting -(0 to 0.99): capacitive; +(0 to 0.99) inductive
• First disconnect supply power from the measured circuit or the power
consumer, and discharge any capacitors.

CATV 600V Measurement Locations
4mm
• Ensure the test lead shield is pressed firmly in place. Failure to use the CATIV shield increases arc-flash risk.
CATII 1000V Measurement Locations
18mm
• 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.

FCC/IC INFORMATION
NOTE: This device complies with Part 15 of the FCC Rules and CAN ICES-3(A).
Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired operations.
INFORMATION TO THE USER
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the
FCC Rules. These limits are designedto provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
