The meter is a stable multimeter with 3 2/1 LCD displays , 9V drive by
battery. It's widely used on measuring Inductance, resistance,
capacitance, diode, transistor rest and continuity buzzer. It’s an ideal
tool for lab, factory and family.

2. SAFETY NOTE

The meter meets the standards of IEC1010. Read the operation
manual carefully before operation.
1 Do not input DC Voltage or AC Voltage.
2 The voltage below 36V is safety. To avoid electric shock, check

whether the test leads are connected correctly, whether the

insulation is good when measuring over 36DCV or 25ACV , .
3 Remove the test leads when changing function and range.
4 To select correct function and range, beware of error operation.

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.
