Keithley 6487 Reference Manual

12-4 SCPI Signal Oriented Measurement Commands Model 6487 Reference Manual
D) MEASure[:<function>]? Configure and perform “one-shot” measurement
<function> = CURRent[:DC] Measure current
This command combines all of the other signal oriented measurement commands to per-
form a “one-shot” measurement and acquire the reading.
When this command is sent, the following commands execute in the order that they are
presented.
• CONFigure:<function>
• READ?
When :CONFigure is executed, the instrument goes into a “one-shot” measurement mode.
