Testing Resistors
Resistance values ranging from 0.5Ω to 2MΩ can be
measured, with a minimum resolution of about 0.3Ω.
Resistance is measured using a DC signal with a peak voltage
of 1V (across an open circuit) and a peak current of about 3mA (through a
short circuit).
Resistor results: Following analysis, the
resistance value is displayed.
Low Resistance/Inductance
Low value inductors (<5µH) and low value resistors (<10Ω) are treated as a
special case by the Atlas LCR. This is because low value inductors and low
value resistors can exhibit very similar characteristics at the test frequencies
available from the Atlas LCR.
The following message is displayed:
Pressing the scroll-off button will
display the values of resistance and
inductance that the Atlas LCR has
measured.
The test frequency displayed is the
frequency used for the measurement of
the inductance.
Please note that probe compensation is particularly important when
analysing low value inductors, capacitors and resistors.
