4. INDUCTANCE (L) MEASUREMENT
PROCEDURE
1)Slide the " LC/R select switch " ( 3-3, Fig. 1 ) to the " LC "
position.
2)Rotate the function switch for the maximum expected
inductance range.
3) Fully discharge any charged inductors.
4)Insert the tested inductor into socket " L/C Measuring
input terminal 1 " ( 3-5, Fig. 1 ). Alternatively, connect
the inductor to " L/C Measuring input terminal 2 " ( 3-6,
Fig. 1 ). via using the measuring alligators supplied .
Note :
a. If the inductance value is unmarked start with the
highest range and keep decreasing until a suitable
reading is obtained.
b. Measurement of very low inductance should be
performed using extremely short leads in order to
avoid introducing any stray inductance.
c. This instruments 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. CAPACITANCE (C) MEASUREMENT
PROCEDURE
1)Slide the " LC/R select switch " ( 3-3, Fig. 1 ) to the " LC "
position.
7
2)Rotate the function switch for the maximum expected
capacitance range.
3) Fully discharge any charged capacitors.
4)Observe polarity when connecting polarized capacitors.
5)Insert the tested capacitor into socket " L/C Measuring
input terminal 1 " ( 3-5, Fig. 1 ). Alternatively, connect
the capacitor to " L/C Measuring input terminal 2 " ( 3-6,
Fig. 1 ) via using the measuring alligators supplied .
6)The Display value indicated corresponds to the range
selected. If the Display shows " 1 ", it indicates an out
of range selected measurement, then select to the next
higher range.
Note :
a. If the capacitance value is unmarked start with the
highest range and keep decreasing until a suitable
reading is obtained.
b. A capacitor with low voltage leakage will read over
range, or a much higher value than normal. An
open circuit capacitor will read zero on all ranges
possibly a few pF on 2 nF range due to stray
capacitance of the instrument.
c. Measurement of very low capacitance should be
performed using extremely short leads in order to
avoid introducing any stray capacitance.
d. When using the test leads, remember that the leads
may introduce a measurable capacitance to the
measurement.
e. Capacitors, especially electrolytic type, often have
wide tolerances.
