done by judging the impedance property of component according to the test result. It
is quite convenient for the measurements of mixed and unknown components.
Enable Auto LCR Mode
Long press of AUTO button will activate auto LCR mode. The “AUTO” indicator on
LCD indicates that auto LCR mode is activated.
In auto LCR mode, the match of secondary parameter with primary parameter is
shown as below:
Table1-Matching relations between primary and secondary
parameters in auto LCR mode
Primary Parameter
Secondary Parameter
Capacitance (C)
Dissipation (D)
Inductance (L)
Quality Factor (Q)
Resistance (R)
Phase Angle (
θ
)
In auto LCR mode, series or parallel equivalent mode is selected in accordance with
the magnitude of impedance. Parallel mode is selected at high impedance and series
mode at low impedance.
Disable Auto LCR Mode
Long press the AUTO button again will disable auto LCR mode. In addition, this
mode will not continue through changing the primary and secondary modes,
series/parallel equivalent mode and frequency mode.
“AUTO” indicator on LCD will disappear when auto LCR mode is turned off.
6.9 Measurement Rate (RATE)
There are two selectable measurement rates in this instrument: fast and slow. The
rate of fast measurement is about 4~5times/sec and slow measurement is
approximate 1.5 times/sec. The stability of slow measurement is higher than fast
measurement.
The fast and slow rates can be directly switched by pressing RATE button. “FAST ”
indicator will be displayed on LCD at fast rate and “ SLOW ” indicator at slow rate.
6.10 Series/parallel Equivalent Mode
For the presence of non-ideality and distributed parameters of components, actual
components are frequently taken as combined network of ideal components. In
general, there are two simple equivalent models used in LCR meters, which are
series model and parallel model.
