:SYSTem:ERRor?
Syntax
:SYSTem:ERRor?
Description
Queries and clears an error message from the error queue.
Remarks
The error will be cleared when you read the error queue. You can also clear the error queue by using the
*CLS command or the *RST command; or by turning on/off the instrument.
Return Format
The query returns a string consisting of two parts separated by commas. The first part is the number of the
error message and the second part is the content of the error message. The content is a string enclosed by
double quotation marks. For example, -113,"Undefined header; keyword cannot be found". "-113" is the
number of the error message. "Undefined header; keyword cannot be found" (i.g. the content enclosed by
the double quotation marks) is the content of the error message.
