range
AT281x sets the optimum
impedance range for the
impedance of the DUT
You don’t need to
select range.
The measurement
time is longer due
to the ranging time
Hold
range
Measurement is performed
with a fixed impedance range
No ranging time is
required
You need to select
a proper range
depending on the
value of the DUT.
Nominal
Range
AT281x sets the optimum
range depending on the
nominal value.
You don’t need to
select range. No
ranging time is
required
Valid only in the
sorting mode.
Available impedance range
The hold range has nine impedance ranges: 10, 30, 100, 300, 1k, 3k, 10k,
30k and 100k.
The impedance range is selected according to the DUT’s impedance even if the
measurement parameter is capacitance or inductance.
