Problem
Possible Solution
Capacitance measured
when probes are open
circuit is not close to zero
(±1.0pF).
Perform a probe compensation.
Resistance and/or
inductance measured when
probes are short circuit is
not close to zero
(±1.2Ω, ±1.6µH).
Perform a probe compensation.
Component shown as
Components with an inductance of <10µH
and resistance of <10Ω will be shown as an
Inductor/Resistor because it is not always
possible to measure a discernible difference
at the test frequencies used.
Ensure probes are well connected to the
component under test for a few seconds and
allow the readings to settle.
Ensure that nothing else is connected with
the component under test. Make sure that
you are not touching the connections.
The LCR45 may have selected a mode that
is not optimum for your component, try a
manual mode.
The component value may be outside the
supported measurement range.
Measured value doesn’t
appear to be correct.
The component’s design frequency may not
correspond to the test frequencies used by
the LCR45.
Measured values vary
between readings.
The displayed resolution is higher than the
internal measurement resolution to avoid
rounding errors. Variations within the
quoted measurement resolutions are normal.
Calibration date is
approaching or has past.
Your LCR45 will carry on working after the
“Calibration Due Date” has past. The date is
simply a recommendation.
