1. SAFETY INFORMATION
This multimeter has been designed according to IEC 
1010 concerning electronic measuring instruments with
an overvoltage category ( CAT) and pollution 2.
Follow all safety and operating instructions to ensure
that the meter is used safely and is kept in good
operating condition.
1.1 PRELIMINARY
When using this meter, the user must observe all
normal safety rules concerning:
Protection against the dangers of electrical current.
Protection of the meter against misuse.
Full compliance with safety standards can be
guaranteed only if used with test leads supplied. If
necessary, they must be replaced with the same
model or same electronic ratings. Measuring leads
must be in good condition.
1.2 DURING USE
Never exceed the protection limit values indicated in
specifications for each range of measurement.
When the meter is linked to measurement circuit,
do not touch unused terminals.
When the value scale to be measured is unknown
beforehand, set the range selector at the highest
position.
Before rotating the range selector to change
functions, disconnect test leads from the circuit under
- 1 -

test.
When carrying out measurements on TV or
switching power circuits, always remember that there
may be high amplitude voltages pulses at test points
which can damage the meter.
Never perform resistance measurements on live
circuits.
Always be careful when working with voltages
above 60V dc or 30V ac rms. Keep fingers behind the
probe barriers while measuring.
1.3 SYMBOLS
Important safety information, refer to the operating
manual.
Dangerous voltage may be present.

Double insulation (Protection class )
1.4 MAINTENANCE
Before opening the meter, always disconnect test
leads from all sources of electric current.
For continue protection against fire, replace fuse
only with the specified voltage and current ratings:
F1: F 300mA/250V F2: F 10A/250V
If any faults or abnormalities are observed, the
meter can not be used any more and it has to be
checked out.

Never use the meter unless the back cover is in
place and fastened fully.
To clean the meter, use a damp cloth and mild
detergent only, do not use abrasives or solvents on
it.

3. OPERATING INSTRUCTION
3.1 MEASURING VOLTAGE
1. Connect the black test lead to the COM jack and the
red test lead to the V//F jack.
2. Set the rotary switch at the desired V or V ~range
position and connect test leads across the source or
load under measurement.
3. Read LCD display. The polarity of the red connection
will be indicated when making a dc voltage
measurement.
3.2 MEASURING CURRENT
1. Connect the black test lead to the COM jack and the
red test lead to the mA/Cx jack for a maximum of
300mA. For a maximum of 10A, move the red lead to
the A jack.
2. Set the rotary switch at μA/mA and A range position
to be used and push /~button to select DCA or ACA
measuring mode.
3. Connect test leads in series with the load in which
the current is to be measured.
4. Read LCD display. The polarity of read connection
will be indicated when making a DC measurement.
3.3 MEASURING FREQUENCY
1. Connect the black test leads to the COM jack and the
red test lead to the V//F jack.
2. Set the rotary switch at KHz position and connect test
leads across the source or load under measurement.
- 6 -

NOTE:
The input voltage should be between 200mV and 10V
rms ac. If the voltage is more than 10V rms, reading
may be out of the accuracy range.
3.4 MEASURING RESISTANCE
1. Connect the black test lead to the COM jack and the
red test lead to the V//F jack. ( NOTE :The polarity of
red lead connection is positive“”)
2. Set the rotary switch at desired range position and
connect test leads across the resistance under
measurement.
NOTE:
1. For resistance above 3.26M, the meter may take a
few seconds to stabilize reading.
2. When the input is not connected, i.e. at open circuit,
the figure “OL” will be displayed for the overrange
condition.
3. When checking in - circuit resistance, be sure the
circuit under test has all power removed and all
capacitors are full discharged.
3.5 MEASURING CAPACITANCE
1. Connect the black test lead to the COM jack and the
red test lead to the mA/Cx jack. (NOTE: The polarity of
the red lead is positive “+”.)
2. Set the function switch at nF or μF position to be
used.
3. Connect test leads across the capacitor under
- 7 -

measurement and be sure that the polarity of
connection is observed.
NOTE:
1. When checking in-circuil capacitance, be sure that
the circuit has all power removed and all capacitor are
fully discharged.
2. The range control mode in capacitance
measurement is manual ranging and only two ranges
(326nF, 32.6μF) are provided.
3. If range control button is used in this function
measuring, decimal points may be at incorrect
positions.
4. At the nF range, when the capacitor to be measured
is not connected to test leads, the LCD may not read
zero, but a few counts. These counts have to be
subtracted from measuring results.
3.6 TESTING DIODE & CONTINUITY
1. Connect the black test lead to the COM jack and the
red test lead to the V//F jack. ( NOTE: The polarity of
red lead connection is positive+.)
2. Set the rotary switch at /position and push the
/button to select continuity or diode test mode.
3. In continuity testing, if continuity exists (i.e.,
resistance less than about 50), built-in buzzer will
sound.
4. If diode test mode is selected, connect the red and
black leads to the anode and cathode of the diode
under test. The forward voltage drop of this diode in V
