The PM 6303 RCL meter is used for measurements of
resistances, capacitances and inductances. Providing
auto-function and auto-ranging facility the instrument
allows fast and high precision measurements of passive
components over a wide range.
The component under test is directly connected to the
instrument, either via a two-terminal test fixture, a
four-wire test cable or a four-terminal test adapter. The
measurement result, namely numerical value, dimension and
the equivalent-circuit symbol, is immediately displayed on a
large 4-digit liquid- crystal display (LCD), updated at a
rate of two measurements per second.
A microprocessor controls the measurement process,
computates the measurement value and transfers the result to
In the RCL AUTO mode the dominant component, either R, C or
L of the component under test is automatically selected for
display. RCL AUTO is also the default mode of the instrument
after power- on.
For an inductance e.g. with quality factor 500 > Q > 1 the
instruments indicates the measurement value of the series
inductance and as equivalent-circuit symbol the series
connection of a resistance and an inductance.
In addition to the RCL AUTO mode with display of the
dominating component 8 further parameters can be selected by
2 pushbuttons providing a stepping function, whereby the
appropriate parameter is marked by a LED:
Quality factor Q, dissipation factor D, parallel resistance
Rp* series resistance Rs, impedance Z,
parallel capacitance Cp or parallel inductance Lp, series
capacitance Cs or series inductance Ls* series capacitance,
internally biased Cs (2 V BIAS),
The instrument is especially suited for use in laboratories,
for quality control, service workshops and for education
