:SYSTem:KEY <numeric_value>
4-116
This value is stored in non-volatile memory. It is unaffected by power-on,
save/recall, and *RST.
If parity is enabled, the Counter sends/receives 7 data bits plus 1 parity bit. If
parity is disabled, the Counter sends/receives 8 data bits.
The response is in the following form: <error_number>,
"<error_description>".
The <error_number> is an integer in the range [-32768, 32767]. The negative
error numbers are defined by the SCPI standard; positive error numbers are
particular to this Counter. An error number value of zero indicates that the
Error Queue is empty.
The maximum length of the <error_description> is 255 characters.
The queue is cleared (emptied) on *CLS, power-on, or upon reading the last
error from queue.
If the Error Queue overflows, the last error in the queue is replaced with the
error -350, "Queue overflow". Any time the queue overflows, the least recent
errors remain in the queue and the most recent error is discarded. The
maximum length of the Error Queue is 30.
This query clears any displayed error message from the front-panel display.
The Error Queue is unaffected by *RST and save/recall.
