Measuring dissipation factor/quality factor/phase angle
(D/Q/θ)
The dissipation factor (D), quality factor (Q), and phase
angle (θ) values can be displayed interchangeably by
pressing the key when the LCR meter is set to the
inductance, capacitance, or impedance measurement mode.
This setting is not applicable for DCR measurement.
Changing the test frequency
The test frequency is set to 1 kHz by default. Press the
key to select a desired test frequency.
Selecting parallel/series circuit mode (P/S)
The LCR meter can display parallel ( ) or series
( ) mode data for all ranges.
Press the key for more than 1 second to toggle the
parallel and series mode.
Series mode is set as the default setting. You can, however,
change this power- on behavior in the Setup menu. See
“Changing the initial power- on behavior” on page 56 for
more information on how to change the default measurement
mode (parallel or series) for subsequent power cycles.
