Device Clear

Device Clear

The full capability of the Device Clear IEEE 488.1 interface function is implemented in the Counter. This function allows a device to be initialized to a cleared state. The device-dependent effect is described below.

In response to either the Device Clear message or the Selected Device Clear message, the Counter:

∙clears the input buffer and Output Queue,

∙resets the parser, execution control, and response formatter,

∙clears any command that would prevent processing a *RST or other commands,

∙disables the effect of a prior *OPC command, and

∙terminates the holdoff action of a *WAI, *OPC?, or data query (:MEASure query, :READ query, :FETCh query, :CALC:DATA?, :CALC2:LIM:FAIL?) waiting for pending operation to complete.

Also, a front-panel initiated diagnostic or calibration may be aborted (for example, if the front-panel diagnostic or calibration is waiting for user input).
