Resistor Selection for Current Measurement
By selecting different resistors, you can measure very large
current with low impedance or measure smaller current very
precisely. The table summarizes the approximate range, and
resolution (without over-sampling) for current measurements
using the included resistors.
Note that the range for the 0.1
Ω resistor is limited by the
power rating.
In addition to the included resistors, you can use any resistor
(rated for the maximum current and power you intend to
apply). In general, select a lower resistance for measuring
higher current or a higher resistance for lower current. For
very low resistance, a simple piece of wire will suffice.
