Problem
|
Cause and Solution
|
|
|
Capacitance measured when probes are
open circuit is not close to zero (±0.6pf)
|
Slight variations in open circuit
capacitance are normal, perform a probe compensation
procedure.
|
|
|
Resistance and/or inductance
measured when probes are short circuit is not close to
zero (±1.2 ohms, ±1.6uH)
|
Slight variations in short circuit
resistance and inductance are normal, perform a probe
compensation procedure.
|
|
|
Measured value doesn't appear to be
correct.
|
Ensure probes are well connected to
the component under test for the entire duration of
the analysis.
Ensure that nothing else is
connected with the component under test. Make sure you are
not touching the connections.
The component value may be
outside the supported measurement range.
The component's design frequency
may not correspond to the test frequencies used by the
Atlas LCR.
|
|
|
Measured values vary slightly
between tests.
|
The displayed resolution is finer than the internal measurement resolution to avoid rounding
errors. Small variations within the quoted measurement
resolutions are normal.
|
|
|
Calibration date is approaching or
has past.
|
Don't worry, the Atlas LCR will
carry on working after the "Calibration Due
Date" has past. The date is simply a recommendation
and may be required for the purposes of satisfying your
own quality procedures. Click here
if you would like us to recalibrate your unit.

|
|
Probe(s) has become detached.
|
The probes simply fit to the test
leads using square-pin connectors to allow for various
accessories. Simply push them back together.
|
|
|
Display shows "Low Resistance
and Inductance" when testing some components, why
won't it measure them?
|
It will measure them. This message
is displayed when the Atlas LCR is measuring a low
resistance and low inductance component and cannot be
certain whether it is an inductor or a resistor (as they
can have very similar properties at low values). Simply
press scroll on the unit and you will see
the measurements.
