Details
Automatic range changes slow down the reading rate. By setting upper and lower measurement
range limits, you can prevent inadvertent range changes to ranges that you are not going to use. Note
that these limits can only be set for Auto V-source Ohms. They are not available for Manual V-source
Ohms.
The upper range limit is selected by specifying the maximum expected reading that you expect to
measure. For example, if the maximum expected reading is approximately 1 G
, let the parameter
(
<n>
) = 1e9.The lowest (most sensitive) range that can measure 1 G
is the 2 G
range. Thus, the 2
G
range is selected as the upper range limit. With this upper limit, the instrument cannot uprange to
the 20 G
(or higher) measurement range.
The lower range limit is selected by specifying the lowest expected reading that you expect to
measure.
