5.2 CONSIDERATION OF MEASUREMENT
(1) This LC METER is intended for measuring the capacitance value
of a capacitor, the inductance value of an inductor. It is not
intended for determining the “Q” factor for above reactive
components. Misleading readings may be obtained if the
measurement of the inductance or cap acitance of a resistor is
attempted.
(2) When measuring components in circuit, the circuit must be
switched off and de-energized before connecting the test leads.
(3) For all measurements, should connect BLACK test lead to “ -”
terminal and RED test lead to “+” ter minal.
5.3 INDUCTANCE (L) MEASUREMENT PROCEDURE
(1) Press the POWER button to turn the power on
(2) Select the range switch for the maximum expected inductance.
(3) Connect the alligator clips to the inductor leads.
(4) Read the display. The value is direct reading in th e electrical units
(uH, H) indicated at the selected switch. If DISPLAY show “1”. It
indicates on Out-of-Range measurement. If the display indicates
one of more reading zeros, shift to the next lower range scale to
improve the resolution of the measurement .
NOTE:
(a) If the inductance value is unmarked, start from the 2mH range and
keep increasing until the over range indication goes off and a
reading is obtained.
(b) Very low inductance measurement should be performed by using
extremely short leads in order to av oid introducing any stray
inductance.
(c)This instrument is not intended for determining the “Q” factor for the
inductor. Misleading readings may be obtained if the measurement
of the inductance of a resistor is attempted.
5
5.4 CAPACITANCE(C) MEASURING PROCE DURE
(1) Press the POWER button to turn the power on
(2) Select the range switch for the maximum expected capacitance.
(3) Fully discharge any capacitors.
(4) Connect the alligator clips to the capacitor leads.
(5) Read the display. The value is direct reading in the electric al unit
(nF, uF) indicated at the selected range switch. If DISPLAY show
“1”, It indicate on Out-of-Range measurement. If the display
indicates one or more leading zeros, shift to the next lower range
scale to improve the resolution of the measurement.
NOTE:
(a) If the capacitance value is unmarked, start from the 2nF range
and keep increasing until the over -range indication goes off and a
reading is obtained.
(b) A shorted capacitor will read over-range on all ranges. A
capacitance with low voltage leakage will r ead over range, or a
much higher value than normal.
An open capacitor will read zero on all ranges (possible a few pF
on 2nF range, due to stray capacitance of the instrument).
(c) Very low capacitance measurement should be performed by using
extremely short leads in order to avoid introducing any stray
inductance
(d) When using the optioned test leads, remember that the leads
introduce a measurable capacitance to the measurement. As a
first approximation, the test capacitance did measured by opening
the leads at the trips, recording the open circuit value and
subtracting the value.
(e) Capacitors, especially electrolytic, often have notoriously wide
tolerances. Do not be surprised if the measured value is greater
than the value marked on the capacitor, unless it is a close
tolerance type. However, value is seldom drastically below the
rated value.

5.5 RESISTANCE (Ω) MEASURING PROCEDURE
(1) Press the POWER button to turn the power on
(2) Select the range switch for the maximum expected resistance.
(3) Insert the black test leads into the “COM” jack, and the red one
into the “V/Ω/Hz” jack;
(4) Turn the range switch to resistance po sition, and then connect the
test leads at the two ends of the resistor.
(5) If DISPLAY show “1”, It indicate on Out -of-Range measurement. If
the display indicates one or more leading zeros, shift to the next
lower range scale to improve the resolution of the measurement.
Note:
(a) When input is open circuit, it will display status 1;
(b) When measuring resistance on line, ensure that all power of
circuit tested are turn down and all capacitor are discharged
completely;
(c) Never input voltage if in resistance measurement mode!
(d) It normal for resistance higher than 1MΩ that the reading data is
not stable for the first several seconds;
5.6 Transistor hFE
1. Press the POWER button to turn the power on
2. Turn the range switch to “hFE” position;
3. To determine the transistor ’s type, NPN or PNP, insert the emitting,
base and collector electrode into the corresponding jacks in testing
accessory.
5.7 DIODE AND CONTINUITY TEST
1. Press the POWER button to turn the power on
2. Insert the black test leads into “COM “jack, and the red one into the
“Ω ” jack;
3. connect test leads in parallel to the diode tested, with the red test
leads to the anode and the black to cathode, then the reading value
will be approximate forward voltage drop of the diode;
4. Connect pencils to two points of the circuit to be tested, if buzzer
sounds, then the resistance between the two points is lower than
7
(60±20) Ω.
5.8 DATA HOLD
Press HOLD, the peak value of current data will be keep displaying on
LCD; press it again to cancel this functio n.
6. MAINTENANCE
DO NOT try to verify the circuit for it’s a precision meter.
1. Beware of waterproof, dustproof and shockproof.
2. Do not operate and store the meter in the circumstance of high
temperature, high humidity, and flammability, explosive an d strong
