4 Principle of Operaon
Fig. 1 shows the LCR meter block-diagram. Voltage from the
voltage source through a liming 100 Ω resistor 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
either posive or negave 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 proporonal to the current flowing through
the measured component. Aer digizing the ADC signals the
impedance is calculated according to the formula DUT
impedance Z =Rj* Vau/Vaj.
Inial values of Impedance (offsets) obtained during calibraon
with Open and Short probes are stored in the non-volale
memory of the device and are considered in the calculaon of
the impedance of the measured component thus eliminang the
offsets due to the device internal parasics.
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
Capacive and at Xs (Xp) > 0 the reactance is Inducve.
4.1 Calculaon of Parameters:
Capacitance C = 1/(2π f |Xs|) where f is the test frequency.
Inductance L = Xs/(2π f ). Q = |Xs|/Rs. D = 1/Q. |Z| =

In automac mode the device automacally selects the opmum
frequency and the equivalent circuit for measurements. Users
can also manually select measurement mode and frequency of
the test signal can be selected a range of fixed values from 100
Hz to 250 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 Ohm’s law, the DC
current Resistance (RDC) is calculated.
By applying the DC voltage in forward and reverse direcon, the
diodes are detected, and the polarity of p-n juncon is
determined.
For capacitors larger than 40 mF the capacitance is calculated
using the voltage variaon on the measured capacitor when it is
charging for a certain me interval and applied current.
The principle of the frequency meter is based on the counng of
pulses of the reference generator between the two ramps of the
input signal for a certain period of me (by default about 1
second). At the same me, the quanty of periods of the input
5 © Copyright Siborg Systems Inc.

signal is counted too. Then the frequency f is calculated by the
formula f = M/N* f
r where M is the number of periods of the
input signal, N is the number of pulses from the reference
generator and f
r is the frequency of the reference generator.
The principle of measuring the voltage is based on comparing the
input signal with the reference voltage.
5 Safety Measures and General Instrucons
For safe and reliable operaon of the device, follow these rules:
1. Never do measurements in a live circuit
2. Never apply voltage to the probes
3. Never measure Charged Capacitors
4. Do not make measurements while the device is charging
5. Charge the baery using a USB port of a computer or a DC

7. This device is designed for indoor use only.
8. To prevent injury from sharp ends of the test leads,
transport the device in the case provided.
9. Do not touch non-insulated test lead surfaces during
measurements, it will affect the result. Keep fingers on the
insulated surfaces of the handles.
10. Replacement of the baery must be carried out by a
specialist. Baeries must be recycled or disposed of
separately from regular household waste. Do not burn the
baery.
6 Device Controls
The device is controlled by a 4-way joysck. Joysck funcons are
different when it is held for 1, or 2 beeps. Figure below shows
the joysck locaon on the housing with arrows indicang the
push direcons and the number of beeps required to call the
funcon.
The arrows show the direcon of the joysck push. A single
arrow denotes holding for one beep, two arrow heads denote
holding for two beeps before releasing.

(default). The automac turn-off me seng can be changed
in the menu: System /Power/Time Off
6.3 Charging the Baery
The device is powered by a Li-Po baery with 3.7 V rated voltage.
The baery icon on the display shows the remaining charge of
the baery. This icon will blink when
the device’s power is below 3.6 V and
will automacally turn off at 3.5 V.
Informaon about the baery voltage can be displayed by
selecng: System/Power/Baery Voltage
Charge the baery by connecng it via a micro-USB cable
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.
6.4 Main and System Menu
The main menu is shown when the joysck is pressed. The main
menu is mul-levelled. Select the appropriate menu item by
moving the joysck up or down and pressing down to select.
To set the default operang mode (R-L-C-D, RDC+LED, Voltage,
etc.), press and hold the joysck for two beeps. This mode is then
stored in the device memory and will be acvated when the
device is powered on next me.

7 Modes of Operaon
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
joysck to the right for one beep. A typical screen for R-L-C-D
mode looks as follows:

7.1.1 Measurements
When the measured component is connected to the test leads,
the screen displays informaon depending on the component
and the selected sengs in the R-L-C-D mode menu.
Inductance Capacitance
Resistance Diode
In automac mode, measurement of capacitance larger than 0.9
μ F 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
addional numbers are displayed indicang the capacitor
parameters described below.
The main criterion for rejecon of electrolyc 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
electrolyc capacitors and the other for Low ESR capacitors
(presented below in Supplement A and B). These are indicave
values and should only be used for a rough esmaon of the
capacitor performance. In this case besides the measured ESR
value, two addional numbers are displayed in the right top
poron of the screen. The first number indicates the 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 posive number indicates rejecon,
whereas for Low ESR values above -10. The 2nd number is the
selected operang 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 evaporaon of
the electrolyte and other degradaon mechanisms. In such cases
the table cannot be used for accurate capacitor evaluaon.
If you wish to measure capacitance larger than 0.9 μ F at a
specific frequency you have to adjust frequency by pushing the
joysck to the le for one beep or select frequency in the R-L-C-D
parameter sub-menu by pushing the joysck to the right for one
beep to acvate the hidden sub-menu. In this case both the
capacitance and the secondary parameter (ESR or D) are

measured at the same selected frequency.

7.1.2 Quick Controls
● Push the joysck up and hold for 1 beep to change the primary
impedance type (more info below, Secon 7.2.1)
● Push the joysck to the right and
hold for 2 beeps to make
Open/Short calibraon and
eliminate the offsets.
● Push the joysck le 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 joysck down and hold for 1 beep to change the test
signal level cyclically Auto-1.0-0.5-0.1 Vrms
7.1.3 Relave (Tolerance) Measurements
In order to iniate Relave (Tolerance) measurement mode,
connect the measured reference component to the probes, push
the joysck 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 deviaon from the reference
value. To cancel Relave measurements, push the joysck down
for two beeps.
7.1.4 Open/Short Calibraon
Before the first use, the device must be calibrated with Open and
Short probes for both RDC+LED (for a correct diode parameter
extracon) and R-L-C-D mode for each test frequency. When the
device is set to Auto-frequency the device is automacally
calibrated at 100Hz, 120 Hz, 1 kHz, 10kHz, and 100kHz.
If the probes are shorted, parasic resistance is obtained and
accounted for. If the probes are open, parasic capacitance is
obtained. Please use LCR-Reader Capacitance Calibraon Board
to set a proper distance between the test leads for Open circuit
calibraon (according to the component size) because the
parasic capacitance depends on the distance between the test
leads. Short circuit calibraon is very crucial for small resistance
and inductance and large capacitance. Open circuit calibraon is
crucial for small capacitance and large resistance.
To eliminate the offset, push the joysck to the right, hold for 2
beeps and release. When measuring small capacitances less than
100 pF, use LCR-Reader Offset Calibraon Board included in the
package for the open calibraon. Insert the test leads at the
© Copyright Siborg Systems Inc. 10

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 ps of any dirt and
oxides and calibrate with short probes.
7.1.5 Capacitance Offset Calibraon Board
The Capacitance Offset Calibraon Board provides a reliable
method of determining the parasic offset between the test
leads. The dummy PCB uses holes to represent various sizes of
components.
To use the calibraon board, place the test leads into the holes
corresponding to the size of the component under test; make
open calibraon by pushing the
joysck 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
sengs push the joysck to the right
and hold for 1 beep, the following
menu will appear. The menu tree is
shown in detail in the following
diagram:
11 © Copyright Siborg Systems Inc.

7.2.1 Primary Parameter
In Auto mode the type of measured component is determined
automacally: R: Resistor, L: Inductance, C: Capacitor, D: Diode. In
addion to the component type selecon 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 secon 7.2.14 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. Automac secondary
parameter selecon 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 you to manually select the frequency of
the test signal. In Auto mode, the device automacally selects a
frequency of 100Hz, 1 kHz or 10 kHz, depending on the rang
and type of the component. For electrolyc 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 juncons of semiconductor
components. This, in turn, may cause errors in the
measurements. In order to avoid
the effect of p-n juncons, the
signal level is automacally
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 direcon of the p-n juncon as shown
below.
7.2.5 Period
Increased measurement me results in more stable readings,
reduced me results in faster updates on the screen.
7.2.6 SER/PAR Mode
This is used to select the equivalent circuit depending on the
characteriscs of the element. For Capacitance measurements in
© Copyright Siborg Systems Inc. 12

Automac equivalent circuit regime and Auto signal level Serial
circuit is used for impedance values lower than 100 Ohms. If
signal level is not in the Auto regime, serial equivalent circuit is
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 Source Impedance
Auto – 100 R – 1600 R
7.2.9 I-V Curve
When this mode is selected, the device will switch to Analog
Signature Analysis (ASA or I-V tesng). This is a troubleshoong
technique where current-limited AC sine wave is applied across
two points to locate damaged and marginal components.
The display plots the voltage across the device under test as the
horizontal axis and the current as the vercal axis. Different
signatures are produced depending on the current flow as the
applied voltage changes.
The four basic signatures are displayed Resistance, Capacitance,
Inductance and Semiconductor:
Resistance is displayed as a straight line at an angle from 0 to 90
degrees with the slope
depending on the resistance.
The higher the value of
resistor, the closer the line
will get to the horizontal (an open circuit)
Capacitance is displayed as a circle or ellipse. A low value
capacitor will have flaened,
horizontal ellipcal
signatures; a capacitor with
high values will have
flaened, vercal ellipcal
signatures. Signature of an ideal capacitor would be nearly a
perfect circle.
Inductance is displayed as circular or somewhat ellipcal due to
parasic resistance.
Inductors are displayed as
flaened, horizontal ellipses;
an ideal inductor would
produce a perfect circle.
Inductors generally require low source impedance and higher
test frequencies to display a nice ellipcal signature.
13 © Copyright Siborg Systems Inc.

Semiconductors/diodes are
displayed as two or more line
segments that resemble a
right angle showing both
forward and reverse bias. The vercal segment displays the
forward bias region and the turn-on voltage and drop; the
horizontal part of the curve is the reverse voltage region where
the diode is effecvely an open-circuit and non-conducng.
Shorts are displayed as vercal lines because the current flow is
theorecally infinite; an open circuit would display as a horizontal
line due to the current always being zero.
7.2.10 Cap-Voltage
This seng must be selected in
the menu when evaluang
electrolyc capacitors for
rejecon 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
7.2.11 Data 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 aer 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
acvated when the device is turned on next me, select the
mode, press the joysck and hold for 2 beeps. This measurement
seng will be stored in the device’s non-volale memory for all
other measurements unl selecng other parameters or Default
in the menu.
7.2.12 Power Save Mode
On/Off/Exit
7.2.13 Default
By selecng 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
© Copyright Siborg Systems Inc. 14

● Sound is On
● C-voltage is Off
● Data Hold is Off
If you hold the joysck up to 2 beeps, then all parameters are
stored in the non-volale memory and will be loaded when the
device is powered on.
7.2.14 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 sll measured
at 100 kHz. To toggle between the modes, push the joysck le
for 1 beep.
Discharge Capacitor!
Before the first applicaon in this sub-mode it is necessary to
addionally calibrate the device with both open and shorted
probes.
For the rejecon of electrolyc 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, Secon 14.2 and 14.3). Two addional
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, posive values indicate rejecon,
and for Low ESR rejected values are above -10. The second
number is the selected operang voltage of the capacitor in
menu under C voltage: 6.3, 10, 16, 20, 30, 50-63, 100, and 160+
Volts.
7.2.15 Large Cap (0.5 μF to 40 mF) Sengs
● Push the Joysck right for 2 beeps to make calibraon
eliminang the offset. Only short calibraon is required.
● Push Joysck to the le to toggle between lower than 40 mF
and higher than 40 mF capacitance measurements. To speed
up the seling of the readings, short the capacitor leads for 2-3
seconds before the measurements.
● Push Joysck down for 1 beep to
toggle the test signal level
between 1.0 Vrms and 0.1 Vrms
15 © Copyright Siborg Systems Inc.

7.2.16 Super Large Cap > 40 mF Measurement
• Push the Joysck right for 2 beeps to make calibraon
eliminang the offset. Only short
calibraon is required.
• Push Joysck to the le to toggle
between lower than 40 mF and
higher than 40 mF capacitance measurements. To speed up the
seling of the readings, short the capacitor leads for 2-3
seconds before the measurements.
• Push Joysck 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
evaluang the current via that shunt in a live circuit.
• Press the joysck to open the main menu, select RDC+LED
mode and press the joysck again.
• Before making any measurement, push the joysck to the right
for 2 beeps to calibrate with open and short probes to

To select the Auto Mode push the joysck down.
In the Auto mode resistances and diodes are automacally
detected. For resistors the boom 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 joysck le. If you push le
once again, the diode polarity reverses.
Diode mode is used for LED/diode parameter extracon using DC
bias. It is recommended for in-circuit characterizaon of p-n
juncons. 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 joysck to the le and hold for 1
beep to change the polarity of the probes.

7.3.2 R test at 1.3 V and R test at 100mV
To select the R-test Mode push the joysck up, resistor symbol
will be displayed in the top le corner. If you push up again, the
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 detecon 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 joysck down unl 2 beeps while measuring the shunt
resistor.
7.4 Signal Generator Mode
Only Sine wave signals are
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 exing 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 me is 4 mes longer than the default
in other modes. An external decoupling capacitor is required to
supply a signal to an acve 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 funcon
of automac change of the display orientaon (le/right hand) is
disabled. It is recommended to use LCR-Reader Kelvin Probe
Connector to simplify the device operaon in this mode.
