1. INTRODUCTION

The precise LCR meter series are automatic, user programmable instruments

that provide high reliability and great precision for measuring a wide variety of

impedance parameters. The frequency range of LCR-819/829 covers from 12Hz

to 100kHz, LCR-817/827 from 12Hz to 10kHz, LCR-816/826 from 100Hz to

2kHz, and LCR-821 from 12Hz to 200kHz. The basic accuracy is 0.1% for LCR-

827/829/816/826, 0.05% for LCR-817/819/821. The measured results can be

displayed on the high quality LCD monitor with decimal points and units. The

measured result resolution is five full digits for Inductance (L), Capacitance (C),

Resistance (R) and absolute value of impedance (|Z|) [four full digits for

Dissipation factor (D), Quality factor (Q), R with C, R with L, 2 digits after

decimal dot for phase angle (θ)]. In the meantime, the LCD monitor is also shown

the control status and parameters of settings. The keypads are easy for menu

programming. The LCR Meters’ test fixture (option) is a method of convenient,

reliable, guarded 4-terminal/2 wires connection of radial and axial leaded

components to the LCR Meters. Test conditions can be stored and recalled from

internal memory that will reduce the setup time for measurement preparing.

4. OPERATION

4-1. Connects to DUT

The LCR Meters utilize the structure of four wires measurement which allows

accurate, easy, and stable measurements and avoids mutual inductance and

interference from measurement signals, noise and other factors inherent with

other types of connections. For the accuracy of measurement, GOODWILL

produces the cable set and test fixture (option) for connection directly to the

front panel BNC connectors.

4-2. Start-Up

Connects the power cord of the LCR Meters to the mains socket-outlet. Presses

the

POWER button of front panel to apply the AC power to the LCR Meters.

4-3. Zeroing

In order to eliminate strayed capacitance and impedance of test cable during the

measurement, the LCR Meters should be zeroed to correct for test cable and/or

test fixture errors before taking measurements. The corrections are calculated

and stored in memory of the LCR Meters during the zeroing process. Open and

short circuit zeroing should be done for test cable and/or test fixture. For the best

accuracy, the test cable and/or test fixture should be zeroed once per day at least

and each time test cable or test fixture is changed in general.

The zeroing process of open and short circuits are following:

Open Circuit

z The test cable or test fixture should be open with no component connected. z Press MENU key. z Press F1 key to select “OFFSET” menu. z Press F1 key to select open circuit zeroing (the “CAP OFFSET” is indicated

on the adjacent LCD monitor.).

LCR-800 Series User Manual

z After the BAR at the bottom of LCD monitor is filled to the full, the zeroing

process is done.

z If the zeroing process is successful, a message of “OK” will appear on the

LCD monitor. If failed, a message of “FAIL” will appear on the LCD

monitor.

Short Circuit

z The test cable should be connected or test fixture shorted (using a clean

copper wire, as short as possible).

z Press MENU key. z Press F1 key to select “OFFSET” menu. z Press F2 key to select short circuit zeroing (the “R/L OFFSET” is indicated

on the adjacent LCD monitor.).

z After the BAR at the bottom of LCD monitor is filled fully, the zeroing

process is done.

z If the zeroing process is successful, a message of “OK” will appear on the

LCD monitor. If failed, a message of “FAIL” will appear on the LCD

monitor.

Test Condition:

Test voltage=According to the actual test voltage.

Test speed = According to the actual test speed.

R.H = OFF

C.V = According to the actual test status.

For the summary, the zeroing menu can be chosen through menu selection as

shown in Figure 4-1 above.

NOTE: The “Open Circuit” and “Short Circuit” have to pass the test,

otherwise, the accuracy of the LCR Meters will become worse.

4-4-2. Series & Parallel Equivalent Circuit

Impedance that is neither a pure resistance nor a pure reactance can be

represented at any specific frequency by either a series or a parallel combination

of resistance and reactance. Such representation is called “equivalent circuit”.

The component value of the “Primary Display” depends on which equivalent

circuit (series or parallel) is chosen. In normal, the component manufacturer

shall specify how a component is to be measured (usually series) and at what

frequency. Please refer to Figure 4-4.

Inductors from 1mH to 1H: Series, 1kHz.

Inductors greater than 1H: Series, 0.1kHz.

Capacitors less than 10pF: Parallel, 100kHz.

Capacitors from 10 to 400pF: Series or Parallel, 10kHz.

Capacitors from 400 to 1µF: Series, 1kHz.

Capacitors greater than 1µF: Series, 0.1 or 0.12kHz.

Resistor less than 1kΩ: Series, 1kHz.

Resistor from 1kΩ to 10MΩ: Parallel, 0.25kHz.

Resistor greater than 10 MΩ: Parallel, 0.03kHz

Unless for special reason, always select “Series” for capacitors and inductors.

This has traditionally been standard practice. For very small capacitance or

inductance, select a higher test frequency for better accuracy. For very large

capacitance or inductance, select a lower test frequency for better accuracy. For

dc resistance, select a lower test frequency to minimize ac effects.

Because the reactive component most likely to be represented in a low resistance

resistor is series inductance, the “Series” is selected for a resistor below about

1kΩ. If a resistor large than 10MΩ, select “Parallel” that because the reactive

component most likely to be represent in a high resistance resistor is shunt

capacitance. If the Q is less than 0.1, the measured Rp is probably very close to

the dc resistance.

LCR-800 Series User Manual

The total loss of a capacitor can be expressed in several ways, including D and

“ESR” (Equivalent Series Resistance). “ESR” is typically much larger than

actual “ohmic” series resistance of the wire leads and foils that are in series with

the heart of a capacitor physically, because ESR includes also the effect of

dielectric loss. ESR is related to D by the formula: ESR = Rs = D/ωCs. Where ω

represents “omega” = 2 pi time frequency.

Although it is traditional to measure series inductance of inductors, there are

situations in which the parallel equivalent circuit better represents the physical

component. For small “air-core” inductors, the significant loss mechanism is

usually “ohmic” or “copper loss” in the wire, therefore the series circuit is

appropriate. Nevertheless, for an “iron core”, the significant loss mechanism can

be “core loss”, therefore, the parallel equivalent circuit is appropriate which

being a better model of the inductor.

measurement per second respectively. The trade-off is accuracy vs. speed. LCR-

817/819 will take a more accurate measurement at a slower rate. The trade-off is

as follows

SLOW speed : More than 1 measurement per second, at 0.05% accuracy

(or better)

MEDIUM speed : More than 3 measurements per second, at 0.1% accuracy

(or better)

FAS T speed : More than 7 measurements per second, at 0.24% accuracy

(or better)

There are two available bias voltage modes: “Internal” and “External”.

Internal:

An internal DC 2 volts bias voltage will apply to the device under test.

External:

An external DC bias voltage between 0 and 30 volts can be applied to the device

under test. The external bias connection is located on the rear panel. The

maximum current is 200mA. The supply of bias voltage has to be floating, don’t

connect either side to ground. It’s better to wait approximately 1 second for

taking a reading after initiating a testing process, therefore, the device under test

will stabilize after bias voltage applied. The DC bias voltage should be applied

only to capacitors in general. If the DC bias voltage is applied to device of low

impedance, the unreliable testing results will occur. When the external bias is

applied, please join the function of C.V.ON (Constant voltage On) in use.
