SAFETY INFORMATION
The digital clamp meter has been designed
according to IEC1010 1 and IEC1010 2 032
concerning safety requirements for electrical
measuring instruments and hand-held current
clamps with double insulation overvoltage category
1000V CAT II 600V CAT III and pollution 2.
This meter complies with the requirements of the
following European Community Directives:
89 / 336 / EEC (Electromagnetic Compatibility) and
73 / 23 / EEC (Low Voltage) as amended by 93 /
68 / EEC (CE Marking).
However, electrical noise or intense electromagnetic fields in the vicinity of the equipment may
disturb the measurement circuit.
Measuring instruments will also respond to
unwanted signals that may be present within the
measurement circuit.
Users should exercise care and take appropriate
precautions to avoid misleading.

SYMBOL EXPLANATION
Important safety information, refer to the
operating manual.
Dangerous voltage may be present.
Earth ground.
Double insulation (Protection class 1000V
CAT II 600V CAT III).
SAFETY PRECAUTIONS
Follow all safety and operating instructions to
ensure maximum personal safety during the
operation and to ensure the meter is used safely
and is kept in good operating condition.
●
●
●
Read the operating instructions thoroughly
and completely before operating your meter.
Pay attention to WARNINGS, which will
inform you of potentially dangerous procedures. The instructions in these warnings
must be followed.
Always inspect your meter and test leads for

●
any sign of damage or abnormality before
every use. If any abnormal conditions exist
(i.e. broken test leads, cracked cases,
display not reading, etc.), do not attempt to
take any measurements.
Do not expose the instrument to direct
sunlight, extreme temperature or moisture.
Never ground yourself when taking electrical
measurements. Keep your body isolated
from ground by using dry clothing, rubber
shoes, rubber mat or any approved
insulating material.
You always are careful when working with
voltages above 60V dc or 30V ac rms. Keep
fingers behind the probe barriers while
measuring.
To avoid damages to the instrument, do not
exceed the maximum limits of the input
values shown in the technical specification
tables.
Never use the meter to measure voltages
that might exceed the maximum allowable
input value of any function.

MAINTENANCE
●
●
●
●
●
Never touch exposed wiring, connections or
any live circuit when attempting to take
measurements.
Before opening the case, always disconnect
test leads from all energized circuits.
Never use the meter unless the back cover
is in place and fastened completely.
Do not use abrasives or solvents on the
meter. To clean it using a damp cloth and
mild detergent only.
Qualified and trained service technicians
should only perform calibration and repair of
the meter.
GENERAL DESCRIPTION
The meter is an autorange professional clamp
meter with 5999 counts. For measuring DC and AC
voltage, AC current, Resistance, Capacitance,
Frequency, ADP, Diode, and Continuity Test with
battery operated.
There is the AC measurement to be RMS or TRUE
RMS about the meter. It is chosen as user buy.

Transformer jaws
Pick up the AC current flowing through the
conductor.
Rotary switch
Rotary switch is used to select functions.
HOLD button
When this button is pushed, the display will
keep the last reading and “ ” symbol will
appear on the LCD. Pushing it again returns
the meter to normal mode.

MAX/MIN button
Press the button to enter the MAX/MIN
Recording Hold mode. The maximum,
minimum values are then reset to the
present input. The readings are stored in
memory. “ MAX ” or “ MIN ” annunciator
turns on to indicate what value is being
displayed. Hold this button for more than 3
seconds to return to the normal operating
mode.
