3.3.12
*ESR? – Event Status Register
*ESR? reads the Standard Event Status Register and clears it.
The
ESR is “sticky” in that it keeps its bits high until they are cleared even if the condition that caused
them to be set is no longer true.
The result is in the range 0 to 255.
There is no command to set the ESR.
Reading the ESR clears it. To clear the ESR without reading its contents, see
*CLS.
*ESR? is affected by FORMat:SREGister.
