Glossary
Coil : A coil is made of a multiple turns of wire on conductor / Core. It has the
property to oppose / resist changes in current. It is characterized by its Inductance.
Capacity : Characteristics of a Capacitor. The unit is the Farad (F).
Capacitor : Passive element consists of two conductors / plates separated by a
dielectric. The capacitor has the property of passing the AC while blocking the DC.
See also chapter capacity and reactance.
Test frequency : The frequency with which the measurement of parameters of
component is done. The value of a parameter sometime depend on frequency.
Range : Range of resistance that the instrument uses to perform measuring
function.
Impedance : Complex parameter defining a passive component. It include a real
part (resistance) in series with some imaginary part (reactance ). Standard or pure
resistance has no reactance, while perfect coils and capacitors have resistance.
Inductance : Property of a coil to oppose any change in current . The inductance of
a coil is in Henry (H).

Parameter : Electric property measured, The main or primary parameter is the
property of most commonly sought component (capacity, inductance, Resistance).
The second parameter of lesser importance characterized losses in the
component (quality factor, dissipation, phase angle).
Accuracy : The difference between the measured value and the true value of
component. The accuracy is expressed as a percentage for the principal
parameter. The accuracy depends on the value of the impedance and the
frequency. Typically the accuracy is a secondary parameter and is great
importance.
Accuracy Background : The accuracy of LCR bridge depends on a number of
parameters such as the frequency and impedance. The accuracy of the standard
programmed database is checked with precision instrument in optimum
conditions, i.e. at frequency of 1 kHz and for 100 and 10 k .  
Source Resistance : Resistance in series with the testing signal generator. This
resistance relates to the range of impedance.
Resolution : The smallest value that can be shown on the display of the
instrument. Do not confuse this with the accuracy.
Test Voltage : rms This is the value of the alternating voltage that generates a
current in the test component. Because of resistance and impedance of
component under test, test voltage is always less than specified value.

Power : When push button pressed , switches power ON to the
instrument.
Display : LCD displays the measured value & parameters selected, the
status of the instrument and different messages. In measuring mode the
normal primary value (L, C, R, | Z |) is displayed on the first line while the
associated secondary parameter (Q, D, X, ) is displayed in the second 
line. The position of the decimal point is adjusted according to the function
automatically. The symbol front of the main parameter indicates that 
measurement is a relative measure or an absolute deviation compared to a
nominal value. The presence of an arrow to the left of the first line indicates
that the instrument is in automatic mode. The presence of a single arrow to
the left of the second line indicates the instrument is placed in automatic
equivalent circuit / model mode. The range of impedance is shown right from
the second line. A letter ‘A’ form line number indicates that the instrument is in
the auto range. In manual mode or maintaining same range mode an “H”
becomes flashing. The frequency of testing is underway displayed on the
r i g h t
side of the second line. Test signal level is shown by HI and Lo on
first line on right side. Bias can be selected for biasing components and
shown by arrow on right side of display by arrow when signal is biased.
