4 Principle of Operation
Fig. 1 shows the LCR meter block-diagram. Voltage from the
voltage source through a limiting 100 Ωresistor is applied to the
DUT connected at points A and B. The amplitude and frequency
of the Test Signal V are adjustable. It is also possible to apply

© Copyright Siborg Systems Inc. 4
either positive or negative DC voltage to the DUT. A voltage drop
on the DUT is measured by DAu. The voltage drop on resistor Rj
measured by DAj is proportional to the current flowing through
the measured component. After digitizing the ADC signals the
impedance is calculated according to the formula DUT
impedance Z =Rj* Vau/Vaj.
Initial values of Impedance (offsets) obtained during calibration
with Open and Short probes are stored in the non-volatile
memory of the device and are considered in the calculation of
the impedance of the measured component thus eliminating the
offsets due to the device internal parasitics.
The measured component can be represented as one of the
following equivalent circuits:
(1) and (2): AC measurement series circuits, (3) and (4): AC
parallel circuits, (5,6,7) DC measurement of diodes, resistance
and capacitance.
Impedance in series circuits is Z = Rs + iXs and in parallel circuits
is Z = 1/(1/Rp + 1/iXp) where Xs (Xp) < 0 if the reactance is
Capacitive and at Xs (Xp) > 0 the reactance is Inductive.
4.1 Calculation of Parameters:
Capacitance C = 1/(2πf|Xs|) where f is the test frequency.
Inductance L = Xs/(2πf). Q = |Xs|/Rs. D = 1/Q. |Z| =
In automatic mode the device automatically selects the optimum
frequency and the equivalent circuit for measurements. Users
can also manually select measurement mode and frequency of

5 © Copyright Siborg Systems Inc.
the test signal can be selected a range of fixed values from 100
Hz to 100 kHz. Test voltage can be set to 1.0, 0.5 and 0.1 Vrms.
By passing direct current through the measured component, the
voltage and current can be measured. Using Ω’s law, the DC
current Resistance (RDC) is calculated.
By applying the DC voltage in forward and reverse direction, the
diodes are detected, and the polarity of p-n junction is
determined.
For capacitors larger than 40 mF the capacitance is calculated
using the voltage variation on the measured capacitor when it is
charging for a certain time interval and applied current.
The principle of the frequency meter is based on the counting of
pulses of the reference generator between the two ramps of the
input signal for a certain period of time (by default about 1
second). At the same time, the quantity of periods of the input
signal is counted too. Then the frequency fis calculated by the
formula f = M/N*frwhere M is the number of periods of the
input signal, N is the number of pulses from the reference
generator and fris the frequency of the reference generator.
The principle of measuring the voltage is based on comparing the
input signal with the reference voltage.

to a USB DC voltage source of 5V +/- 5%. The device screen is lit
when the device is charging, and it turns off when the charging is
complete.
6.5 Main and System Menu
The main menu is shown when the joystick is pressed. The main
menu is multi-levelled. Select the appropriate menu item by
moving the joystick up or down and pressing down to select.
To set the default operating mode (R-L-C-D, RDC+LED, Voltage,
etc.), press and hold the joystick for two beeps. This mode is
then stored in the device memory and will be activated when the
device is powered on next time.

7 Modes of Operation
7.1 R-L-C-D Mode
R-L-C-D mode is the default device mode and it is designated for
measurement of Resistors, Capacitors, Inductances and Diodes.
To select the mode, select R-L-C-D in the main menu. In order to
get access to the mode parameters (hidden sub-menu) push the
joystick to the right for one beep. A typical screen for R-L-C-D
mode looks as follows:

9 © Copyright Siborg Systems Inc.
7.1.1 Measurements
When the measured component is connected to the test leads,
the screen displays information depending on the component
and the selected settings in the R-L-C-D mode menu.
Inductance Capacitance
Resistance Diode
In automatic mode, measurement of capacitance larger than 0.9
μF by default is made at 120 Hz, while ESR is measured at 100
kHz. In this case the display looks
as follows. The frequency is not
shown on the screen, but two
additional numbers are displayed indicating the capacitor
parameters described below.
The main criterion for rejection of electrolytic capacitors is the
value of ESR that varies amongst the types of capacitors and
manufacturers. Two ESR tables have been compiled with typical
ESR values for various capacitances/voltages, one for regular
electrolytic capacitors and the other for Low ESR capacitors
(presented below in Supplement A and B). These are indicative
values and should only be used for a rough estimation of the
capacitor performance. In this case besides the measured ESR
value, two additional numbers are displayed in the right top
portion of the screen. The first number indicates quality of the
capacitor measured as a ln(Rs/Rt) where Rs is the measured ESR
value and Rt is the value from the table. For standard aluminum
capacitors a positive number indicate rejection, and for Low ESR
values above -10. The 2nd number is the selected operating
voltage of the capacitor. It should be specified in the menu item
Large Cap/C-voltage. It should also be kept in mind that the
measured capacitance may be significantly lower than the
original data from the data sheet due to evaporation of the
electrolyte and other degradation mechanisms. In such cases the
table cannot be used for accurate capacitor evaluation.
If you wish to measure capacitance larger than 0.9 μF at a
specific frequency you have to adjust frequency by pushing the
joystick to the left for one beep or select frequency in the R-L-C-
D parameter sub-menu by pushing the joystick to the right for
one beep to activate the hidden sub-menu. In this case both the

© Copyright Siborg Systems Inc. 10
capacitance and the secondary parameter (ESR or D) are
measured at the same selected frequency.
Discharge Capacitor!
7.1.2 Quick Controls
•Push the joystick up and hold for 1 beep to change the primary
impedance type (more info below, Section 7.2.1)
•Push the joystick to the right and
hold for 2 beeps to make
Open/Short calibration and
eliminate the offsets.
•Push the joystick left and hold for 1 beep to change the test
frequency. The frequency changes cyclically Auto-100Hz-
120Hz-1kHz-10kHz-100kHz. If the frequency is selected from
the menu in the range 20-75kHz, the frequency changes
cyclically 20kHz-30kHz-40kHz-50kHz-60kHz-75kHz-100kHz
•Push the joystick down and hold for 1 beep to change the test
signal level cyclically Auto-1.0-0.5-0.1 Vrms
7.1.3 Relative (Tolerance) Measurements
In order to initiate Relative (Tolerance) measurement mode,
connect the measured reference component to the probes, push
the joystick up and hold for 2 beeps. The reference value will be
recorded, and further measurements will show the measured
value as well as the percentage deviation from the reference
value. To cancel Relative measurements, push the joystick down
for two beeps.
7.1.4 Open/Short Calibration
Before the first use, the device must be calibrated with Open and
Short probes for both RDC+LED (for a correct diode parameter
extraction) and R-L-C-D mode for each test frequency. When the
device is set to Auto-frequency the device is automatically
calibrated at 100Hz, 120 Hz, 1 kHz, 10kHz, and 100kHz.
If the probes are shorted, parasitic resistance is obtained. If the
probes are open, parasitic capacitance is obtained. Please use
LCR-Reader Capacitance Calibration Board to set a proper
distance between the test leads for Open circuit calibration
(according to the component size) because the parasitic
capacitance depends on the distance between the test leads.
Short circuit calibration is very crucial for small resistance and
inductance and large capacitance. Open circuit calibration is
crucial for small capacitance and large resistance.
To eliminate the offset, push the joystick to the right, hold for 2
beeps and release. When measuring small capacitances less than
100 pF, use LCR-Reader Offset Calibration Board included in the
package for the open calibration. Insert the test leads at the

11 © Copyright Siborg Systems Inc.
distance of the size of the component and calibrate with open
probes. Only then measure the capacitor.
Before measuring small inductances (less than 10 μH) and
resistances (less than 10 Ω) wipe off the tips of any dirt and
oxides and calibrate with short probes.
7.1.5 Capacitance Offset Calibration Board
The Capacitance Offset Calibration Board provides a reliable
method of determining the parasitic offset between the test
leads. The dummy PCB uses holes to represent various sizes of
components.
To use the calibration board, place the test leads into the holes
corresponding to the size of component under test; make open
calibration by pushing the
joystick to the right, hold for 2
beeps and release.
7.2 R-L-C-D mode menu
To open the hidden R-L-C-D mode
settings push the joystick to the right
and hold for 1 beep, the following
menu will appear. The menu tree is
shown in detail in the following
diagram:
7.2.1 Primary Parameter
In Auto mode the type of measured component is determined
automatically: R: Resistor, L: Inductance, C: Capacitor, D: Diode.

© Copyright Siborg Systems Inc. 12
In addition to the component type selection test signal level is
also adjusted when in-circuit measurements are made (see
below 7.2.4). Measurement mode can also be set manually to R,
L, C, Z and Large Cap. The last mode is only for measuring
capacitance values larger than 0.5 μF (see section 7.2.10 below).
7.2.2 Secondary Parameter
In Auto mode for inductors quality Q factor is displayed for Q>1
and series Resistance Rs for Q<1, and for capacitors, loss tangent
for C < 0.5 μF and ESR for C >0.5 μF. Automatic secondary
parameter selection does not work if the Test Signal is set to
Auto, Rs or Rp are used as the secondary parameter in this case.
7.2.3 Test Frequency
This menu item allows to manually select the frequency of the
test signal. In Auto mode, the device automatically selects a
frequency of 100Hz, 1 kHz or 10 kHz, depending on the rating
and type of the component. For electrolytic capacitors 120 Hz is
used for capacitance measurements and 100kHz for ESR. Users
can also manually select the test frequency. A higher frequency
should be used for measuring small values of capacitances and
inductances as well as ESR. Lower frequencies are used to
measure large inductance and capacitance values. Resistance
measurements are always made at 1 kHz unless RDC+LED mode
is selected.
7.2.4 Test Signal Level
For more stable readings, select 1.0 Vrms or Auto signal level.
Auto is best for measuring loose components and in-circuit
measurements of R, C, L. When measuring a component on a
PCB, high test signal may open p-n junctions of semiconductor
components. This, in turn, may cause error in the measurements.
In order to avoid effect of the p-n
junctions, the signal level is
automatically reduced to 0.1 V
peak-to-peak and the impedance is
re-measured. In this case, the screen shows the diode symbol
and the direction of the p-n junction as shown below.
7.2.5 Period
Increased measurement time results in more stable readings,
reduced time results in faster updates on the screen.
7.2.6 SER/PAR Mode
This is used to select the equivalent circuit depending on the
characteristics of the element. For Capacitance measurements in
Automatic equivalent circuit regime and Auto signal level Serial
circuit is used for impedance values lower that 100 Ohms. If
signal level is not in the Auto regime, serial equivalent circuit is

13 © Copyright Siborg Systems Inc.
used for impedance values lower than 1 kOhm. For inductance
only serial mode is used unless parallel mode is explicitly
specified.
7.2.7 Sound
The device will beep when the resistance is less than 10 Ω, or a
short circuit is found.
7.2.8 Cap-Voltage
This setting must be selected in
the menu when evaluating
electrolytic capacitors for
rejection by ESR value. The
voltage value should be taken from the capacitor’s housing. If
OFF is selected, the capacitor parameters such as the capacitor
quality according to the table and nominal voltage will not be
shown on the display
7.2.9 Sample Hold
When selected, the device will hold measurement data on the
screen. A beep will sound when the measurement is made, and
the values are held on the screen after the component has been
disconnected from the device. The device will only reset when a
new component is measured, or the test probes are shorted.
In order to set a default measurement mode that will be
activated when the device is turned on next time, select the
mode, press the joystick and hold for 2 beeps. This measurement
setting will be stored in the device’s non-volatile memory for all
other measurements until selecting other parameters or Default
in the menu.
7.2.10 Default
By selecting Default, the R-L-C-D mode parameters are reset to:
•Primary Parameter is Auto
•Secondary Parameter is Auto
•Frequency is Auto
•Signal Level - 1.0 Vrms
•Measurement Time: 0.5 seconds
•Equivalent Scheme is Auto
•Sound is On
•C-voltage is Off
•Data Hold is Off
If you hold the joystick up to 2 beeps, then all parameters are
stored in the non-volatile memory and will be loaded when the
device is powered on.

7.2.11 Large Cap
In this mode, there are two sub-
modes, one for capacitance values
from 0.5 μF to 40 mF and the other
from 40 mF to 1 F. In the first mode
the capacitance is measured at a frequency of 120 Hz, and the
capacitor's ESR is measured at the frequency of 100 kHz. The
other mode is for capacitance values from 40 mF to 1 F and the
capacitance is measured using DC while ESR is still measured at
100 kHz. To toggle between the modes, push the joystick left for
1 beep.
Discharge Capacitor!
Before the first application in this sub-mode it is necessary to
additionally calibrate the device with both open and shorted
probes.
For the rejection of electrolytic capacitors based on ESR, two
tables are stored in the memory of the device, one for standard
aluminum capacitors and the other for Low ESR capacitors
(Supplement C and D, Section 14.2 and 14.3). Two additional
numbers are displayed at the top-right corner of the screen in
this case: the first number is the quality of the capacitor. For
standard aluminum capacitors, positive values indicate rejection,
and for Low ESR rejected values are above -10. The second
number is the selected operating voltage of the capacitor in
menu under C voltage: 6.3, 10, 16, 20, 30, 50-63, 100, and 160+
Volts.
7.2.12 Large Cap (0.5 μF to 40 mF) Settings
•Push Joystick right for 2 beeps to make calibration eliminating
the offset. Only short calibration is required.
•Push Joystick to the left to toggle between lower than 40 mF
and higher than 40 mF capacitance measurements. To speed
up the settling of the readings, short the capacitor leads for 2-
3 seconds before the measurements.

capacitance measurements. To speed up the settling of the
readings, short the capacitor leads for 2-3 seconds before the
measurements.
• Push Joystick down for 1 beep to toggle the test signal level
between 1.0 Vrms and 0.1 V Vrms Discharge Capacitors
7.3 RDC+LED Mode
This mode is designed to measure DC resistance, parameters of
Diodes/LEDs, and diode leakage currents. Besides, it allows
measuring a shunt resistor on a board that can be used for
evaluating the current via that shunt in a live circuit.
• Press joystick to open the main menu, select RDC+LED mode
and press the joystick again.
• Before making any measurement, push the joystick to the right
for 2 beeps to calibrate with open and short probes to
eliminate the offsets.
Four sub-modes can be selected: Auto, Diode, R test at 1.3 V DC,
R test at 100 mV DC.
7.3.1 Auto Mode
To select the Auto Mode push the joystick down.
In the Auto mode resistances and diodes are automatically
detected. For resistors the bottom line displays the resistance of
the connected element, at the top the current Ir flowing through
it. For diodes, the polarity of the diode, the voltage drop in the
open state and the reverse current Ir are displayed.
7.3.2 Diode Mode
To select the Diode Mode push the joystick left. If you push left
once again, the diode polarity reverses.
Diode mode is used for LED/diode parameter extraction using DC
bias. It is recommended for in-circuit characterization of p-n
junctions. The screen displays the voltage drop in the open state
when the forward bias is applied. If the reverse bias is applied,
OL is displayed instead. Push the joystick to the left and hold for
1 beep to change the polarity of the probes.
7.3.3 R test at 1.3 V and R test at 100mV
To select the R-test Mode push the joystick up, resistor symbol
will be displayed in the top left corner. If you push up again, the

© Copyright Siborg Systems Inc. 16
test voltage toggles between 1.3 and 0.1 Volts. The applied
voltage is indicated by the pulse height in the top row of the
screen.
These modes are used to measure DC resistance, recommended
for in-circuit detection of resistors. It also allows measuring the
selected shunt resistor on the board that could be later used for
current measurements. In order to set the shunt resistor value,
push the joystick down until 2 beeps while measuring the shunt
resistor.
7.4 Voltage Mode
This mode is to measure DC and AC voltage. The device
automatically detects the polarity of the DC voltage. The upper
line of the display shows the values
of the RMS voltage that is equal to
the DC voltage for a DC bias. The
second line shows the peak-to-
peak voltage range which is zero for a DC bias.
7.4.1 Controls
•Push Joystick up for 1 beep to toggle the current/voltage
measurement mode.
In this mode, the voltage value measured on the shunt resistor is
converted into a current and displayed on the screen. In the
upper line of the screen the value of shunt resistance is
displayed, taking into account the input resistance of the device,
and the lower line shows the value of the current. To enter the
resistance of the shunt into the device memory, go to the
RDC+LED mode and select the 1.3 V mode. With the circuit de-
energized, connect the shunt resistor and push the joystick
down, hold for 2 beeps.
•Push the joystick to the left for 1 beep to turn on and off the
capture mode of the maximum and minimum voltage values.
In this mode the device continuously records and displays
minimum and maximum values of the voltage/current as well
as the instant value.

7.7 Signal Generator Mode
Only Sine wave signal is generated.
The signal is applied to the device
probes. It is possible to adjust the
span (peak-to-peak) of the signal from 0.1 to 3.0 V. Parameters
are stored when exiting the mode. On the right of the screen the
voltage span and the waveform icon are shown. The frequency in
Hz is displayed in the center of the screen.
In this mode, the turn-off time is 4 times longer than the default
in other modes. An external decoupling capacitor is required to
supply a signal to an active circuit. It should be connected to the
Blue probe. The Red probe is common, virtual ground. In this
mode, the device does not turn-off by "flipping" and the function
of automatic change of the display orientation (left/right hand) is
disabled. It is recommended to use LCR-Reader Kelvin Probe
Connector to simplify the device operation in this mode.
