11.4.4 Calibrator Status
Error Queue
If an error occurs due to invalid input or buffer overflow, its error code is sent to the error
queue. The error code can be read from the queue with the command FAULT?. The error
queue holds 5 error codes. When it is empty, FAULT? returns 0. The error queue is
cleared when power is reset or when the clear command *CLS is entered.
Input Buffer
Calibrator stores all received data in the input buffer. The buffer holds 250 characters. The
characters are processed on a first in, first out basis.
