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, 0.05% for LCR-817/819, and 0.1% for LCR -816/826/821. 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 (?)). 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
lThe test cable or test fixture should be open with no component connected.
lPress MENUkey.
lPress F1 key to select “OFFSET”menu.
lPress F1 key to select open circuit zeroing (the “CAP OFFSET”is indicated
on the adjacent LCD monitor. ).

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.

Resistor less than 1kΩ: Series, 1kHz.
Resistor from 1kΩto 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 10M Ω, 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.
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

LCR-800 Series User Manual
14
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.

4-5-1. Bias Voltage
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.

4-5-2. Test Frequency
The numerical input of test frequency accepts up to 5 digits with decimal. User
can input any desired frequencies, however, the actual frequency executed for the
LCR Meters is always the closest one of the 504 available frequencies. The 504
frequencies can be calculated by the following formulas:
3kHz/n, where n range is from 13 to 250
(freq. 0.012 to 0.23077kHz)
60kHz/n, where n range is from 4 to 256
(freq. 0.23438 to 15kHz)
200kHz/n, where n range is from 1to 13 (freq. 15.385 to 200 kHz)
The “nominal value” of an available frequency can be calculated from the proper
one of the three formulas.
The range of test frequency between 12Hz and 10kHz is for LCR-817/827,
between 12Hz and 100kHz for LCR-819/829, between 100Hz and 2kHz for
LCR-816/826, and between 12Hz and 200kHz for LCR-821. To select the test
frequency, just key in the desired frequency via these numerical keys, the LCR

4-5-3. D/Q in PPM (parts per million)
If the value of D or Q is less than 0.0100, user can select DQ in PPM to improve
the resolution by a factor of 100. The units of D and Q in PPM are dimensionless
and expressed as a decimal ratio with the multiplier of 1000000. User can just
press compound key 4to select the unit of D or Q in PPM. To disable the DQ in
PPM feature, press the same key again.
4-5-4. Test Voltage
The range of test voltage is from 5mV to 1.275V in increments of 5mV. The
actualvoltage through the DUT is never more than the source voltage. The DUT
impedance and the source resistance of the LCR Meters decide the actual test
voltage. The smallest voltage through the DUT will be 20% smaller of the source
voltage in general. The programming of test voltage is as follows (Figure 4-10):
lPress MENUkey.
lPress F3key to select “SETTING”menu.
lPress F2key to select “VOLT” menu.
lInput the desired value via the numeral keys.
lPress ↵key
lAfter the BAR at the bottom of LCD monitor is filled full y, the “Test
Voltage”input is done.
4-5-5. Constant Voltage Source
If the DUT have to be measured at a particular test voltage, the LCR Meters
provides the constant voltage feature. After “Constant Voltage” is selected, The
LCR Meters will keep a source resistance of 25Ω. Therefore, the test voltage is
constant for any DUT impedance which large than 25Ω. If “Constant Voltage” is
selected, the measurement accuracy will cause a reduction by a factor of three.
User can just press compound key 1to select the feature of “Constant Voltage”.
To disable this feature, press the same key again.

4-5-6. Range Hold
If a DUT is removed from the test cable or fixture during the “Continuous” mode,
the feature of “Range Hold” can avoid range switching. Due to the test time can
be reduced, “Range Hold” is a useful utility for repetitive devices measurement.
User can just press compound key 0to select the feature of “Range Hold”. To
disable this feature, press the same key again.
4-5-7. Averaging
If this function is enable, the testing time will multiple by the number of tests
(from 1 to 255). Hence, the accuracy can be enhanced. The measurement time
will be increased to the contrary. The programming of “Averaging” is as follows
(Figure 4-11):
lPress MENUkey.

4-5-8. Memory
The LCR Meters have two memory functions: Recall and Store. The current
measurement conditions can be saved into the memory unit or recalled a
previously saved measurement conditions set from the LCR Meters memory.
There are 100 memory blocks totally. The programming of “Memory Store /
Recall” can be used as described below (Figure 4-12):
lPress MENUkey.
lPress F3key to select “SETTING”menu.
lPress F1key to select “MEMORY” menu.
lPress compound key 1to recall a previously saved memory block. or

lInput Signals
/I_E_TRIG: This signal is a measurement start signal. To start
measurement by setting low pulse to minimum 5us for
/I_E_TRIG signal. This is a low edge active.
/I_K_LOCK: This signal is to lock all front panel controls. The front panel
is disable when /I_K_LOCK is at low level, and enable
when /I_K_LOCK is at high level.

LCR-800 Series User Manual
32
lMeasurement Complete signal:
/O_INDEX: This signal will go the low level when analog measurement is
completed and will go the high level when next trigger is
active. The handler can then remove the DUT from the fixture
and replace it with another DUT during the time when
/O_INDEXis at low level.
lCompare Output Signals:
/O_BIN_1 -/O_BIN_13 : The GO judgment is active according to the
measured value judgment results (low level),
for example, if the comparator assigns a
component to BIN1, the /O_BIN_1 line will go
the low level till T4 (see Handler Interface
Timing). /O_BIN_2 -/O_BIN_13 are all
inactive (high level).
/O_P_HI: Main parameter failure: When the main parameter is greater than
Max, it will go the low level till T4 (see Handler Interface
Timing).
/O_P_LO: Main parameter failure: When the main parameter is lower than
Min, it will go the low level till T4(see Handler Interface
Timing).
/O_P_OVER: It will go the low level when main parameter is greater than
Max or is lower than Min.
/O_S_REJ,/O_S_OVER: It will go the low level when secondary is greater
than D_Max (if MODE=C/D) or is lower than
D_Min.
LCR-800 Series User Manual

lJudgment Complete Signal
/O_EOM: This signal becomes active (low level) when the measurement
and comparator judgment are completed, and all handler
interface output are stable. It will go the high level when next
trigger Signal (/I_E_TRIG) becomes active (low edge).
