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 capacitance 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 "+" terminal.
5-3.INDUCTANCE (L) MEASUREMENT PROCEDURE
(1) Set POWER switch to "ON" position.
(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 the 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 avoid
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.
5-4.CAPACITANCE(C) MEASURING PROCEDURE
(1) Set POWER switch to "ON" position.
(2) Select the range switch for the maximum expected capacitance.
(3) Fully discharge any capacitors.
