4 Principle of Operaon
Fig. 1 shows the LCR meter block-diagram. Voltage from the
voltage source through a liming 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 posive or negave 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 proporonal to the current flowing through
the measured component. Aer digizing the ADC signals the
impedance is calculated according to the formula DUT
impedance Z =Rj* Vau/Vaj.
Inial values of Impedance (offsets) obtained during calibraon
with Open and Short probes are stored in the non-volale
memory of the device and are considered in the calculaon of
the impedance of the measured component thus eliminang the
offsets due to the device internal parasics.
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
Capacive and at Xs (Xp) > 0 the reactance is Inducve.
4.1 Calculaon 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 automac mode the device automacally selects the opmum
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 direcon, the
diodes are detected, and the polarity of p-n juncon is
determined.
For capacitors larger than 40 mF the capacitance is calculated
using the voltage variaon 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 counng 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 quanty 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 Instrucons
For safe and reliable operaon 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 baery using a USB port of a computer or a DC
charger 5 V +/- 5%. Do not use damaged cables or chargers.
6. Do not stretch the handles for more than 20mm between
the test leads.
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 baery must be carried out by a
specialist. Baeries must be recycled or disposed of
separately from regular household waste. Do not burn the
baery.
6 Device Controls
The device is controlled by a 4-way joysck. Joysck funcons are
different when it is held for 1, or 2 beeps. Figure below shows
the joysck locaon on the housing with arrows indicang the
push direcons and the number of beeps required to call the
funcon.
The arrows show the direcon of the joysck push. A single
arrow denotes holding for one beep, two arrow heads denote
holding for two beeps before releasing.
6.1 Turning on the Device
Press the joysck and hold for 1 beep.

6.2 Turning Off the Device
The device will turn off in the following cases:
1. Press the joysck and hold it unl the display shows
“Shutdown”.
2. The device turns off if it has been inacve for 120 seconds
(default). The automac turn-off me seng can be changed
in the menu: System /Power/Time Off
6.3 Charging the Baery
The device is powered by a Li-Po baery with 3.7 V rated voltage.
The baery icon on the display shows the remaining charge of
the baery. This icon will blink when
the device’s power is below 3.6 V and
will automacally turn off at 3.5 V.
Informaon about the baery voltage can be displayed by
selecng: System/Power/Baery Voltage
Charge the baery by connecng 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 joysck is pressed. The main
menu is mul-levelled. Select the appropriate menu item by
moving the joysck up or down and pressing down to select.
To set the default operang mode (R-L-C-D, RDC+LED, Voltage,
etc.), press and hold the joysck for two beeps. This mode is then
stored in the device memory and will be acvated when the
device is powered on next me.

7 Modes of Operaon
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
joysck 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 informaon depending on the component
and the selected sengs in the R-L-C-D mode menu.
Inductance Capacitance
Resistance Diode
In automac 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
addional numbers are displayed indicang the capacitor
parameters described below.
The main criterion for rejecon of electrolyc 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
electrolyc capacitors and the other for Low ESR capacitors
(presented below in Supplement A and B). These are indicave
values and should only be used for a rough esmaon of the
capacitor performance. In this case besides the measured ESR
value, two addional numbers are displayed in the right top
poron 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 posive number indicates rejecon,
whereas for Low ESR values above -10. The 2nd number is the
selected operang 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 evaporaon of
the electrolyte and other degradaon mechanisms. In such cases
the table cannot be used for accurate capacitor evaluaon.
If you wish to measure capacitance larger than 0.9 μ F at a
specific frequency you have to adjust frequency by pushing the
joysck to the le for one beep or select frequency in the R-L-C-D
parameter sub-menu by pushing the joysck to the right for one
beep to acvate the hidden sub-menu. In this case both the
capacitance and the secondary parameter (ESR or D) are
