Range and digits
Range
The selected measurement range affects the accuracy of the measurements as well as the
maximum signal that can be measured. Note that with the output off, dashed lines are displayed
(i.e., --.---- µA), to indicate that measurements are not being performed.
Available ranges
The SourceMeter consists of a mainframe and a Remote PreAmp. The mainframe can be
used with or without the Remote PreAmp. However, when not using the Remote PreAmp, the
lower current ranges and higher resistance ranges are not available. Table 6-1 lists the available
ranges for the SourceMeter.
