This clamp meter was designed with a view to complying with
the safety requirements of standard IEC 61010-1. Complies
with the 600V CAT III measurement category and Category
2 contamination requirements. Before using this measuring
instrument, please read this instruction manual and observe
the relevant safety precautions. CAT III: Measurements inside
buildings or plants. For example, fixed equipment, distribution
panel, cabling, bus bars, switches, surge protection distribution
box, etc. CAT II: Measurements on circuits that are directly
connected to low voltage circuits. For example, measurements
on household appliances, portable devices and similar
equipment. CAT I: Measurements on electric circuits that are not
directly connected to mains.
Warning!
These operating instructions contain the information
and warnings required for the safe use and maintenance of the
unit. Read and understand the instructions for use before using
the device. Failure to understand the instructions or observe
the warnings can result in serious personal injury or property
damage. For your safety, please use the probe cable included
with the clamp meter. Before use, please check that your
multimeter is intact and serviceable.

Maintenance
Do not attempt to remove the clamp meter’s outer casing. Before
opening the battery compartment lid, always unplug the probe
cables from the circuit and the clamp meter. The removal of
the clamp meter’s case as well as its calibration, maintenance
and servicing should only be performed by a specialist who is
completely familiar with the operation of the clamp meter and the
shock hazard involved. If not planning to use the clamp meter for
an extended period of time, please remove the battery and avoid
storing the unit in excessively warm or humid environments. Do
not use any abrasives or solvents on the device. Only use a
damp cloth or mild detergent for cleaning the unit.
During Use
• If the unit is used near strong electromagnetic interference,
please note that the measuring instrument’s operation can
become unstable or it may indicate malfunction.
• Never exceed the safety limits specified in the instructions for
each measurement range.
• Never use the unit without its rear panel fully attached.
• Remove from circuit and discharge the high voltage capacitors
before measuring resistance or interruption.
• Be very careful when working with bare cables or bus bars.
• If any irregular operation is detected on the clamp meter,
immediately switch it off and have it serviced.
• If the value to be measured is unknown, check the highest
possible measurement range on the multimeter, or whenever
possible, select the automatic measurement range mode.
• Before turning the selector dial, disconnect the probe cable from
the measurement circuit.
• Never perform resistance or interruption measurements on
energized circuits.
• When performing measurements on TV sets or circuits with
high AC, always remember that there might be high amplitude
voltage on the test points, which can damage the multimeter.
• If the voltage to be tested exceeds the effective value of 60 V
DC or 30 V AC, work carefully in order to avoid sustaining an
electric shock.
• If the battery symbol appears on the display, the battery must
be replaced immediately. Low battery voltage may result in
measurement errors, electric shock, or even injury.
• Keep your fingers away from the connecting sockets.
• Do not use the clamp meter in the presence of flammable gas,
vapours or dust.
• Before each use, check the unit in order to ensure proper
operation (e.g., using a known voltage source).
• When measuring CAT III voltage, the voltage may not exceed
600 V.
General description
This AC/DC clamp meter features a 4 digit, 7-segment display.
It can be used to measure direct current, alternating current,
DC voltage, AC voltage, resistance, frequency, capacity, duty
factor, diodes, and interruption. The minimum and maximum
measured reading can be saved. Capable of performing relative
measurements, has background illumination, and automatically
or manually switches measurement ranges. The reading can be
saved on the display. Switches off automatically.

If more than one secondary function is available at
any given dial setting, this pushbutton can be used
to toggle them. Each push of the button shifts to the
next function.
