Secondary Parameter (SEC)
The secondary display of the LCR meter is used to display measured values of four parameters,
which provide additional information about the component being tested. These parameters
are: D (Dissipation factor), Q (Quality factor), θ (Phase angle), and ESR (Equivalent series
resistance).
To change between these measurements parameters, press the button. The parameters
for measurement will change and repeat upon each button press. On the screen, the indicators
“D”, “Q”, “θ” or “ESR” will be displayed to indicate which secondary mode the meter is in.
Auto Detect Mode (AUTO)
Auto detect function will automatically select the corresponding primary parameter and its
secondary parameter and suitable series/parallel equivalent mode of L, C, R. The selection is
done by evaluating the impedance property of the component according to the test result. This
mode is convenient for the measurements of mixed or unknown components.
Enable Auto Detect 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, each primary parameter has a secondary parameter associated with it,
shown below:
Table 1- Auto LCR Mode
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.
