3. MEASURING INSTRUCTION
3.1 DC Voltage measurement
1) Connect the black test lead to "-" polarity and red test lead to
the "+" polarity.
2) Set the selector switch to desired "VEF" position, LCD display
scan and connect the probes across the source or load under
measurement or push SELECT key to AUTO DC test
3) Read the result from the LCD panel.
3.2 AC Voltage measurement
1) Connect the black test lead to "-" polarity and red test lead to
the "+" polarity.
2) Set the selector switch to desired "VEF" position, LCD display
scan and connect the probes across the source or load under
measurement or push SELECT key to AUTO AC test
3) Read the result from the LCD panel.
3.3Resistance measurement
1) Connect the black test lead to "-" polarity and red test lead to
the "+" polarity.
2) Set the selector switch to desired "ΩCAP " position, the
present function is SCAN mode; also push the SELECT to select
AUTO resistance measurement.
3) Connect the probes across circuit to be tested.
4) Read the result from the LCD panel.
Caution: Ensure that the circuit to be tested is "dead". Max.
input over-load: 250V rms＜10sec
3.4 Capacitance measurement
1) Connect the black test lead to "-" polarity and red test lead to
the "+" polarity.
2) Set the selector switch to desired "ΩCAP " position, the
present function is SCAN mode; also push the SELECT to select
AUTO capacitance measurement.
3) Connect the probes to the capacitance to be tested.
4) Read the result from the LCD panel.
Caution:
a) Capacitors should be discharged before being tested.
b) Max input over-load: 250V rms＜10sec
3.5 Diode test
1) Connect the black test lead to "-" polarity and red test lead to
the "+" polarity.
2) Set the selector switch to "ΩCAP " position. The present
function is SCAN mode; also push the SELECT to select MANU
diode measurement.
3) Connect the black and red test probe to the cathode (-) and
anode (+) ends of diode to be tested respectively, read the
forward voltage drop (junction) value from the display. If reverse
connected the probes to diode, display shows over-load.
Caution: Ensure that the circuit to be tested is "dead". Max input
over-load: 250V rms＜10sec
3.6 Audible continuity test
1) Connect the black test lead to "-" polarity and red test lead to
the "+" polarity.
2) Set the selector switch to "ΩCAP " position. The present
function is SCAN mode; also push the SELECT to select MANU
continuity measurement.
3) Connect the probes across circuit to be tested; the beeper
sounds continuously if the resistance is less than approx. 30Ω.
Caution: Ensure that the circuit to be tested is "dead". Max input
over-load: 250V rms＜10sec
3.7 DC/AC 30mA/300mA
1) Connect the black test lead to "-" polarity and red test lead to
the "+" polarity.
2) Set the selector switch to desired "mA" position, LCD
display scan and connect test leads in series with the
load under measurement or push SELECT key to AUTO
AC test.
3) Read the result from the LCD panel.
3.8 Electric Field Detector (EF mode)
1) Set selector switch to desired "VEF" position. Push SELECT
key to MAMU EF test.
2) Take the top of clamp to approach tested electric field (The
distance is Less than 1cm), When no or less electric field is
detected, the LCD shows “EF”. If the detector senses electric
field, the strength will be showed on LCD by “-“not digits type.
Level 1(weak) is “-“and the level 4(strong) is “----“. Additional
buzzer will be sounds. The buzzer frequency depends on the
strength of electric field also. The Faster beeper means the
stronger electric field (ac voltage) is sensed.
3.9 SCAN Mode Function
1) In voltage or current mode, the AC or DC signals auto
scanning.
2) In ΩCAP (passive component) mode, resistance
(including Continuity), capacitance or diode
measurements are allowed by fully automatic detection;
Note:
a) At measurement ACV or ACA, Don’t identify ac signal when
the ac signal less than 1~5% of range, lese push the SELECT
key to AUTO AC range test.
b) At measurement resistance, don’t test when the resistance
value more than 3MΩ, Please push the SELECT key to AUTO Ω
range test.
c) At measurement capacitance, Don’t test when the
capacitance value more than 600μF, Please push the SELECT
key to AUTO capacitance range test.
4.1 CARING FOR YOUR MULTIMETER
Your Digital Multimeter is an example of superior design and
craftsmanship. The following suggestions will help you care for
the multimeter so you can enjoy it for years.
1) Keep the multimeter dry. If it gets wet, wipe it dry immediately.
Liquids can contain minerals that can corrode electronic circuits.
2) Use and store the multimeter only in normal temperature
environments. Temperature extremes can shorten the life of electronic
devices, damage batteries and distort or melt plastic parts.
3) Handle the multimeter gently and carefully. Dropping it can
damage the circuit boards and cause and can accuse the
multimeter to work improperly.
4) When take current measurement, keep the cable at the
center of the clamp will get more accurate test result.
5) Keep the multimeter away from dust and dirt, which can
cause premature wear of parts.
6) Wipe the multimeter with a damp cloth occasionally to keep it
looking new. Do not use harsh chemicals, cleaning solvents, or
strong detergents to clean the multimeter.
7) Use only fresh batteries of the required size and type. Always
remove old or weak batteries. They can leak chemicals that
destroy electronic circuits.
8) Please take out the battery when not using for a long time.
4.2 battery replacement
1) Ensure the instrument is not connected to any external circuit.
Set the selector switch to "OFF" position and remove the test
leads from the terminals.
2) Open the cover of the battery cabinet by a screwdriver.
3) Replace the old batteries with the same type batteries.
4) Close the battery cabinet covers and fasten the screw.
