SCPI commands

SCPI commands to source-measure and measure only are provided in Table 6, and the
commands to measure ohms are provided in Table 7.

*For manual ohms, you must configure the SourceMeter to source-measure. Table 11 provides a programming
example to measure ohms using the manual ohms method.

Programming examples

Source-measure example — Table 8 shows a typical command sequence to source 10V and
measure current on the 10mA range.

To measure V only, you must source I. To measure I only, you must source V.
The source must be set to 0V or 0A.
When measuring V only, DO NOT use auto range.
When measuring V only, voltage compliance MUST be set higher than the voltage being measured.
