7. OPERATING INSTRUCTIONS
7-1 Attention before operation
7-1-1 Check 9V battery. If the battery voltage is less than 7V, display will
show “ ”, the battery should be replaced at this time to ensure mea-
suring precision.
7-1-2 Pay attention to the “ ” besides the input jack which shows that the
input voltage or current should be within the specified value.
7-1-3 The range switch should be positioned to desired range for measu-
rement before operation.
7-2 Measuring DC Voltage
7-2-1 Connect the black test lead to COM jack and the red to VΩmA jack.
7-2-2 Set the rotary switch at the desired V range position.
7-2-3 Connect test leads across the source or load under measurement.
7-2-4 You can get reading from LCD. The polarity of the red lead connec-
tion will be indicated along with the voltage value.
NOTE:
1. When the value scale to be measured is unknown beforehand, set the
range selector at the highest position.
2. When only the figure’1’ or ‘-1’ is displayed, it indicates over-range situa-
tion and the higher range has to be selected.
3. “ ” means you can’t input the voltage more than 600V, it’s possible
to show higher voltage, but it may destroy the inner circuit or pose a
shock.
4.Be cautious against shock when measuring high Voltage.
7-3 Measuring AC Voltage
7-3-1 Connect the black test lead to COM jack and the red to VΩmA jack.
7-3-2 Set the rotary switch at the desired V~ range position.
7-3-3 Connect test leads across the source or load under measurement.
7-3-4 You can get reading from LCD.
NOTE:
1. When the value scale to be measured is unknown beforehand, set the
range selector at the highest position.
2. When only the figure’1’ or ‘-1’ is displayed, it indicates over-range situa-
tion and the higher range has to be selected.
3. “ ” means you can’t input the voltage more than 600V, it’s possible to
show higher voltage, but it may destroy the inner circuit or pose a shock.
4. Be cautious against shock when measuring high Voltage.
7-4 Measuring DC Current
7-4-1 Connect the black test lead to COM jack and the red to the VΩmA
jack for a maximum 200mA current, for a maximum 10A current,
move the red lead to the 10A jack.
7-4-2 Set the rotary switch at the desired A range position.
7-4-3 Connect test leads in series with the load under measurement.
7-4-4 You can get reading from LCD. The polarity of the red lead connec-
tion will be indicated along with the current value.
NOTE:
1. When the value scale to be measured is unknown beforehand, set the
range selector at the highest position.
2. When only the figure’1’ or ‘-1’ is displayed, it indicates over-range situa-
tion and the higher range has to be selected.
3. “ ” means the socket mA’s maximum current is 200mA and 10A’s ma-
ximum current is 10A, over current will destroy the fuse. Since 10A is
not fused, the measuring time should be less than 1 second to prevent
precision from affecting by circuit heating.
7-5 Measuring Resistance
7-5-1 Connect the black test lead to COM jack and the red to VΩmA jack.
7-5-2 Set the rotary switch at the desired Ωrange position.
7-5-3 Connect test leads across the resistance under measurement.
7-5-4 You can get reading from LCD.
NOTE:
1. When only the figure’1’ or ‘-1’ is displayed, it indicates over-range situa-
tion and the higher range has to be selected.
2. For measuring resistance above 1MΩ, the mete may take a few seconds
to get stable reading.
3. When the input is not connected, i.e. at open circuit, the figure ‘1’ will be
displayed for the over-range condition.
4. When checking in-circuit resistance, be sure the circuit under test has
all power removed and that all capacitors have been discharged fully.
5. The value scale to be measured is unknown beforehand, set the range
selector at the highest position.
7-6 Diode Testing
7-6-1 Connect the black test lead to COM jack and the red to VΩmA jack.
(the polarity of red lead is ‘+’)
7-6-2 Set the rotary switch at the range position.
7-6-3 Connect the red lead to the anode and the black lead to the cathode
of the diode under testing.
7-6-4 You can get a reading from LCD.
NOTE:
1. The meter will show approximate forward voltage drop of the diode.
2. If the lead connections is reversed, only ‘1’ will be displayed.
7-7 Continuity Testing
7-7-1 Connect the black test lead to COM jack and the red to VΩmA jack.
7-7-2 Set the rotary switch at the range position.
7-7-3 Connect test leads across two points of the circuit under testing.
7-7-4 If continuity exists (i.e. resistance less than about 50Ω),
built-in buzzer will sound.
NOTE:
If the input open circuit, the figure ‘1’ will be displayed.
8. Maintenance
8-1 Before attempting to remove the battery door or open the case, be sure
that test leads have been disconnected from measurement circuit top
avoid electric shock hazard.
8-2 To avoid electrical shock, remove test leads from measurement circuits
before replacing the fuse. For protection against fire, replace fuses only
with specified ratings: F-250mA/600V fuse.
8-3 Your must replace the test leads if the lead is exposed, and should
adopt the leads with the same specifications as origin.
8-4 Use only moist fabric or small amount of detergent but not chemical
solution for cleaning.
8-5 do not use the meter before the back cover is properly closed and
screw secured. Upon any abnormality, stop operation immediately and
send the meter for maintenance.
8-6 Please take out the battery when not using for a long time.

User information ex art. 26 D. 49/2014
The symbol labelled on the appliance (Annex IX D. 49/2014) indicates that
the rubbish is subject to “separate collection” and it has been placed on the
Italian market after the December 31, 2010.
The user must therefore assign or (have collected) the rubbish to a
treatment facility according to indications by the local administration, or
hand it over to the reseller in exchange for an equivalent new product. The
separate collection of the rubbish and the subsequent treatment, recycling
and disposal operations encourage the production of appliances made
with recycled materials and reduce negative effects on health and the
environment caused by improper treatment of rubbish.
In the case of very small WEEE (no external dimension more than 25 cm),
the user is eligible to get free of charge assignation to retail shops with sales
areas relating to EEE of at least 400 m².
