Command Syntax

:SYSTem:DEFault

Description

Returns FlexOTO and any connected extended module ( DCA-M) to its default settings. It is a good practice to set FlexOTO to its default state at the start of each program. This is the same actions as using the *RST common command.

An autoscale is not performed.

Use of an *OPC? query to pause program execution while waiting for this command to execute.
