Taking Readings Using The :Read? Command - Keithley 2182 User Manual

Taking readings using the :READ? command

This programming example demonstrates a simple method for taking and displaying (on the
computer CRT) a specified number of readings. The number of readings is specified by the
:SAMPle:COUNt command. When :READ? is asserted, the specified number of readings is
taken. After all the readings are taken, they are sent to the computer. Note that these readings are
also stored in the buffer.
The following program takes 10 readings on the DCV1 function and displays them on the
computer CRT.
