4 Principle of Operation
Fig. 1 shows the LCR meter block-diagram. Voltage from the voltage source through a limiting 1 kOhm
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 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.
Values of Impedance obtained during calibration with Open and Short probes are stored in the non-
volatile memory of the device and are taken into account 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 in one of the following equivalent circuits:
[1] and [2]: series circuits
[3] and [4]: parallel circuits
Impedance in series circuits Z = Rs + iXs and in parallel circuits 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 Formulas to Determine the Parameters:
Electrical capacitance C = 1/(2πf|Xs|) where f is the test frequency.

LCR-Reader-MP Manual Siborg Systems Inc. 6
Inductance L = Xs/(2πf). Q = |Xs|/Rs. D = 1/Q. |Z| =
The device automatically selects the optimum frequency and the equivalent circuit for
measurements. Users can also manually select measurement mode and frequency of the test signal
can be selected from 100 Hz to 100 kHz. Test voltage can be set to 0.65 Vrms 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 (R) can be calculated [6].
By applying the DC voltage in forward and reverse direction, the diodes [5] are detected and the
polarity of p-n junction is determined.
Charging and discharging the capacitor [7] by changing the voltage on the measured component for
a fixed time interval to determine capacitance for capacitors above 40 mF.
The principle of the frequency counter is based on the counting 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 f is the number of periods of the input signal, M is the
number of periods of the input signal, N is the number of pulses from the reference generator and fr
is the frequency of the reference generator
The principle of measuring the voltage is based on comparing the input signal with the reference
voltage.

7 Modes of Operation
7.1 R-L-C-D Mode
This menu item is for measurement of Resistors, Capacitors, Inductances and Diodes. To select the
mode, select R-L-C-D in the main menu. A typical screen looks as follows:
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.
Capacitance Inductance
Resistance Diode
In automatic mode measurement of capacitance larger than 1 μF is made at 120 Hz, while ESR is
measured at 100 kHz. In this case the frequency of the test signal is not shown on the screen. For ESR
based rejection of electrolytic capacitors two tables are used, one for standard aluminum electrolytic
capacitors and the other for Low ESR capacitors.

LCR-Reader-MP Manual Siborg Systems Inc. 10
In this case two additional figures are displayed. The first number is the quality of the capacitor. 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 can be specified in the menu item
Large Cap/C-voltage.
Discharge Capacitors before testing!
7.1.2 Quick Controls
•Turn the jog-wheel clockwise* and hold for 1 beep to change the test parameters (more info
below)
•Turn the jog-wheel counter clockwise 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
•Turn the jog-wheel clockwise and hold for 2 beeps to eliminate the offset. If the probes are
shorted, parasitic resistance is obtained. If the probes are open, parasitic capacitance is
obtained. Please use LCR-Reader Calibration Board to set a proper distance between the test
leads (according to the component size) because the parasitic capacitance depends on the
distance.
•Turn the jog-wheel counter-clockwise and hold for 1 beep to toggle the signal level between
Auto and fixed 0.65Vrms
•If the probes are not connected to anything, press and hold up to 2 beeps to toggle the test
frequency between Auto and 100 kHz. If a part is connected to the probes, then relative
measurements are made showing the difference from the first measured component. Additional
symbol in the top-middle of the screen is displayed.
*When connected to the Capacitance is greater
than 1 μF range for the operating voltage
7.1.3 Open/Short Calibration
Before the first use, the device must be calibrated with Open and Short probes for each test frequency.
When the device is set to Auto-frequency the device automatically calibrates at 100Hz, 1 kHz, 10kHz,
and 100kHz.
To eliminate the offset, turn the jog-wheel clockwise, hold for 2 beeps and release. When measuring
small capacitances less than 100 pF, use LCR-Reader Offset Calibration Board included in the package.

LCR-Reader-MP Manual Siborg Systems Inc. 11
Insert the test leads at the distance of the size of the component and calibrate with open probes. Only
then measure the capacitor.
Before measuring small inductances (less than 1 μH) and resistances (less than 10 Ohm) wipe off the tips
of any dirt and oxides and calibrate with short probes.
7.1.4 Offset Calibration Board
The Offset Calibration Board provides a reliable method of determining the parasitic offset
between the tips. The dummy PCB uses holes to represent various sizes of components.
To use the board, place the tips into the corresponding holes to the size of component under
test; set open/short calibration by turning the jog-wheel clockwise and hold for 2 beeps and
release. The result is the actual value of the component.
7.2 R-L-C-D mode menu
7.2.1 Primary Parameter
In Auto mode the type of measured component is determined automatically: R: Resistor, L: Inductance,
C: Capacitor, D: Diode. Measurement mode can also be set manually to R, L, C, Z as the impedance.

LCR-Reader-MP Manual Siborg Systems Inc. 12
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 < 1μF and ESR for C> 1 μF. Automatic secondary parameter selection
does not work if the Test Signal is set to Automatic, R is used as the secondary parameter in this case.
7.2.3 Test Frequency
This menu item allows to select the frequency of the test signal. In Auto mode, the device automatically
selects a frequency of 100Hz, 120 Hz, 1 kHz or 10 kHz, depending on the rating and type of the
component. Users can also manually select the test frequency. A higher frequency is used for measuring
small values of capacitances and inductances. Resistor measuring are always made at 1 kHz unless
RDC+LED Mode is selected. If 100 kHz frequency is required, press the jog-wheel and hold for 2 beeps.
7.2.4 Test Signal Level
For more stable readings, select 0.65Vrms or Auto signal level. Auto is best for measuring loose
components and in-circuit measurements of R, C, L. When measuring on boards, if at high test signal
level opens p-n junctions of semiconductors components causing an error in the measurements, then
the signal level is automatically reduced to 0.1 V peak-to-peak and the value is re-measured. In this case,
the screen shows the diode symbol and the direction of the p-n junction.
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.
7.2.7 Sound
The device will beep when the resistance is less than 10 Ohm or a short circuit is found.
7.2.8 C-Voltage
This setting has to be selected in the menu when evaluating electrolytic capacitors for rejection by ESR.
The voltage is written on the capacitor’s housing.
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.

LCR-Reader-MP Manual Siborg Systems Inc. 13
In order to set the default measurement mode when the device is turned on, select the mode, press the
jog-wheel 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 Large Cap
In this mode, capacitance and ESR of capacitors from 1 μF to 40 mF are measured. The capacitance is
measured at a frequency of 50Hz, and the capacitor's ESR is measured at the frequency of 100 kHz.
Discharge Capacitors before testing!
If open p-n junctions of semiconductor components cause an error in the measurements, then the
screen shows the diode symbol and the direction of the p-n junction is shown instead of the primary
parameter type.
If the resistance of the component is less than 10 ohms, there will be short beeps. Before the first
application in this sub-mode it is necessary to calibrate the device with both open and shorted probes.
For the rejection of electrolytes 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. Two additional numbers are
displayed on 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 selected operating voltage of the capacitor in menu under C voltage: 6.3, 10, 16,
2, 3, 50-63, 100, and 160+ Volts. This menu opens by clockwise turn of the jog-wheel.
7.2.11 Large Cap (1 uF to 40 mF) Settings
•Clockwise for 1 beep to open the mode menu.
•Clockwise for 2 beeps to make calibration eliminating the offset. Only short calibration is
required.
•Counter clockwise for 2 beeps to toggle the test signal level between 0.65 Vrms and 0.1
V peak-to-peak.
7.2.12 Super Large Cap > 40 mF Measurement
• When in the Large Cap mode, counter clockwise for 1 beep to switch to DC capacitance
measurement mode for Capacitors larger than 40 mF up to 680 mF. To speed up the settling
of the readings, short the capacitor leads for 2-3 seconds before the measurements. Counter
clockwise for 1 beep again to return to the normal Large Cap mode.

•Counter-clockwise for 1 beep to measure of a positive or negative pulse.
7.8 Signal Generator Mode
Sine, triangle, and rectangle signals are generated. The signal is applied to the device probes. It is
possible to adjust the span (peak-to-peak) of a signal from 0.1 to 2.8 V, a constant bias of ± 0.6 V *, and a
duty cycle of 5 - 95% in 5% increments. Parameters are stored when exiting the mode. On the right of
the screen from top to bottom: sweep, offset, duty cycle and the waveform icon. The frequency in Hz is
displayed in the center of the screen.
The self-shutdown time is 4 times longer than the default in other modes. An external decoupling
capacitor is required to supply a signal to a circuit under voltage. It should be connected to a probe
located closer to the side switch. The other probe is a common one. In this mode, the device does not
turn-off by "flipping" and the function of automatic change of 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.
