5. Capacitance Measurement by LCR Meter 4284A
The correct capacitance measurement method using a typical LCR meter 4284A and
measurement jig 16034E is described in this section.
5-1. Turn on the power of LCR meter
This measurement equipment requires warm-up time. Turn the power on for the meter 30
minutes before starting actual measurement.
5-2. Installing the measuring jig on the meter
Install the measurement jig on the meter as shown in Fig.12.
5-3. Setting the LCR meter
Setup measurement conditions using
“

”
screen (see Fig.13).
(1) FUNC
Cp-D,
(2) FREQ and LEVEL
See Table 1.

Note 1: If FREQ and/or LEVEL is not correctly set, you will not be able to correctly
measure the capacitance. These settings are explained in the following
example:
Example: Sample capacitor 1812 type X5R-characteristic 100
F
Correct settings for the frequency and AC voltage are
“
FREQ: 120Hz
”
and
“
LEVEL: 0.5Vrms
”
respectively (see Fig.14). If capacitance is measured using different conditions, such as1kHz
and 1Vrms, the capacitance will be incorrectly displayed, as being 20% lower than if measured
using the correct conditions as shown in Fig.15.
