Remote Control Commands
Optical Power Meter 71
IEEE 488.2 Commands—Quick Reference
*RST
Description This command empties the step response list. It is only seen
when it is part of another multiple command. In the example
below, by adding this command after *IDN?, you will not be
able to access the answer. The *RST, in this instance, erases the
identification string. In addition, this command performs the
following operations:
1. Return to initial state before command was sent, and not
necessarily to previous settings.
2. Force the device to enter into an Operation Complete
Command Idle State (OCIS).
3. Force the device to enter into an Operation Complete
Query Active State (OQAS).
4. Initialize previous responses unless there has been a
program message terminator preceded by an *RST.
