4.Description of impedance parameters
Impedance measuring instruments can be divided into DC impedance and AC impedance
according to different measuring signals. Generally, the multimeter measures DC impedance,
and HW-LCR06 digital bridge can measure DC impedance and AC impedance. Impedance is the
most basic parameter for evaluating electronic components and circuit systems. In DC mode,
the resistance of linear two terminal devices is defined by Ohm`s law. In AC mode, the
ratio of voltage to current is complex. An impedance vector includes the real part
(resistance R) and the imaginary part (reactance X). Impedance is expressed in the form of
R+jX in rectangular coordinate system, or amplitude | Z | and phase angle in polar coordinate
system ¥è The relationship between them is as follows:
Rs = |Zs| cos¥è
Xs = |Zs| sin¥è
Xs/Rs = tan¥è
¥è = tan-1(Xs/Rs)
If ¥è> 0, reactance inductive
If ¥è< 0, reactance capacitance 5.Measurement mode
Impedance can be measured in series and parallel modes. In parallel mode, impedance Z can
be expressed as mutual admittance of Y.
Y=G+JB, G is conductance and B is admittance.

8. Operation Guide
1). Automatic measurement:
When the instrument is turned on, the default state is the automatic identification
mode, Auto LCR, and the default frequency is 1KHz. In the automatic mode, the instrument
automatically recognizes the impedance characteristics of the object, and automatically
selects the main parameters and secondary parameters of L, C, R and their appropriate
series-parallel connection method.
The corresponding relationship between the main parameters and the secondary parameters
of the automatic mode is as follows:
Capacitance C Loss Factor D
Capacitance L quality factor Q
Capacitance R phase angle ¥è
In the automatic measurement mode, the series-parallel connection method depends on the
impedance of the measured object. When the impedance is high (>10K¥Ø), the parallel
connection method is automatically selected, and when the impedance is low (<10K¥Ø), the
series connection method is automatically selected.
2). Data Hold
Press the "HOLD" key for a long time during the measurement to enter the data holding, and the LCD displays the data holding symbol "HOLD". Press the "HOLD" key again to exit
the data holding and return to the normal measurement mode.
3). L/C/R mode measurement parameters
Manual L/C/R mode selects the corresponding parameters.
1) Main parameter selection, in the power-on state, the default is AUTO LCR, press
the "FUNC" key,cycle selection"ATUO LCR"-"ATUO L"-"ATUO C"-"ATUO R"-"DCR"? "ATUO LCR".
2) For sub parameter selection, press "SER/PAL" key in the corresponding main
parameter measurement mode to switch the series/parallel measurement mode, and press
"D.Q ¥è¡± Key to select sub parameters "D", "Q"¡°
¥è¡±¡¢ "ESR" (Note: if the series
measurement mode is "ESR" and the parallel measurement mode is "RP",)
The sub parameters cannot be set in "AUTO R" or "AUTO DCR" mode.
¨ç Measure the capacitance in the "AUTO LCR" mode. If the capacitance value is<5pF,
the equivalent parallel resistance Rp is used to replace the D loss factor for the sub
parameter;
¨è When entering the "AUTO R" or "AUTO DCR" measurement in the "AUTO LCR" mode,
some sub parameters will not be displayed on the LCD.
4). Measurement frequency
HW-LCR06 provides 5 frequency test points, 100Hz/120Hz/1KHz/10KHz/100KHz, the default
frequency is 1KHz when starting up, press the "FREQ" button to select different frequency
points for measurement.
Note: "AUTO DCR" mode is DC impedance measurement, the measurement frequency is
ignored.
5). Deviation ratio setting
The deviation setting is used to compare the deviation ratio of two components. The
main display is the main value of the tested component, and the secondary display is the
deviation percentage. The LCD main display value is automatically recorded as the nominal
value.
Percentage display range: -99.9%~99.9%
The displayed percentage is:
REL%=( DCUR-DREF)/DREF*100%
DCUR: the main parameter value of the component under test
DREF: Nominal value entered
If DCUR >2DREF or 2DCUR < DREF, the secondary display is "0L%", and the main display is the
main parameter value of the component under test.

or "AUTO DCR", and confirm the tested
The terminal has been connected to the measured component, press the "REL" key to
enter the deviation proportion measurement mode, and the LCD will display¡°
¥Ä¡± Symbol.
The main display is the main parameter value of the tested component, and the secondary
display displays the percentage deviation in percentage. Press the "REL" key again, the
main display will display the nominal value on the LCD¡°
¥Ä¡± The symbol flashes and the
sub display shows the percentage deviation. Press the "REL" key again to return to the
normal deviation measurement mode.
(2) Exit deviation measurement
Long press the "REL" key to exit the deviation measurement and return to the normal
mode. 6). Screening measurements
The screening measurement mode is used to quickly screen components whose main
parameters are within a certain range. Press the "FUNC" key to select the appropriate
mode, "AUTO L", "AUTO C", "AUTO R" or "AUTO DCR". Confirm that the test terminal has been
connected to the tested component. Long press "FREQ" for about two seconds, release the
key to enter the Screeninging mode, and the LCD will display the "Sorting" symbol. The main
display is "PASS", and the secondary display displays the main value of the tested
component and enters the nominal value.Replace the tested element. If it is within the
screening limit, the main display will display "PASS", the secondary display will display
the main value of the tested element, and the buzzer will ring once Limit range: the main
display "FAIL" and the secondary display display the main value of the tested element.
(1) Screening range setting
Screening limit mode can be set as: ±0.25%, ±0.5%, ±1%, ±2%, ±5%, ±10%, ±20%,
+80%~-20%.The default range is ±1%. In the main screening mode, press the "SETUP" button
to enter the setting, the "Range" symbol on the LCD will flash, press "ENTER" to confirm
and enter the main parameter value setting, the last digit of the main parameter on the
LCD will flash, Press the "

main parameter to the left, and the corresponding value can be adjusted , press the
"Enter" key to enter the Screening range setting, the "TOL±1%" symbol on the LCD flashes,
press the " " or " " key to adjust the Screening range value, press "ENTER" to confirm
the setting, and then the component can be screened Measurement.
(2) Exit Screening mode
Press the "Sorting" key to exit the sorting measurement mode and return to the normal
mode.
7). Calibration function
The calibration function can effectively reduce the distributed parameter interference
caused by the test line. The calibration function includes short circuit calibration and
open circuit calibration. The short circuit calibration can reduce the impact of contact
resistance and test line resistance on the measurement of low impedance components; Open
circuit calibration can reduce the influence of the distributed capacitance and resistance
of the test line on the measurement of high impedance components.
(1) Enter the calibration function
Start up and long press the "CAL" key to enter open circuit calibration. The LCD sub
display displays
. Then press the "CAL" key to start calibration. The LCD displays a
30 second countdown. When the countdown reaches 0, the LCD displays
.
It indicates that the open circuit calibration is completed. Press the "CAL" key, the
LCD sub display displays
, insert the probe, short-circuit the clamp, and press the "CAL"
key to open At the beginning of calibration, the LCD displays a 30 second countdown. When the
countdown reaches 0, the LCD displays
, indicating that the short circuit calibration
is completed, and then press the "CAL" key to return to the normal test mode.
Note: Open circuit calibration if LCD displays
, It indicates that the
calibration failed. Check whether the test terminal is in open circuit state, and
ensure that the open circuit is calibrated again.
