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
LCR40
. This is because low value inductors and low value
resistors can exhibit very similar characteristics at the test frequencies
available from the
LCR40
.
The following message is displayed:
Pressing the
scroll-off
button will
display the values of resistance and
inductance
that
the
LCR40
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.
