H. Error Messages
-170 Expression error
An error not included in error numbers between -171 and -179 occurs during the syntax
analysis of equation data.
-171 Invalid expression
The equation data element is invalid. (Refer to IEEE488.2,7.7.7.2.) For example,
parentheses are not paired or a character violates the standard.
-178 Expression data not allowed
An equation data element is received where the 4287A does not accept any equation data
element.
-200 Execution error
A comprehensive execution error occurs for which the 4287A cannot detect further details
of the error. This error code simply indicates the occurrence of an execution error that is
defined in IEEE488.2,11.5.1.1.5.
-211 Trigger ignored
A trigger command or trigger signal is received and recognized by the 4287A, but it is
ignored due to the timing relationship with the 4287A. For example, this happens when the
4287A’s trigger system is not in the Waiting for Trigger state).
-213 Init ignored
Another measurement is being executed and the measurement start request (:INIT
command on page 287) is ignored.
-221 Setting conflict
A program data element complying with the syntax standard is analyzed, but the 4287A
cannot execute it at present.
-222 Data out of range
A data element (that does not violate the standard) is received out of the range defined for
the 4287A.
-223 Too much data
The received block, equation, or string type program data complies with the standard but
the amount of data exceeds the limit that the 4287A can handle due to memory or
device-specific conditions related to memory.
-224 Illegal parameter value
The value of the parameter is not allowed.
-230 Data corrupt or stale
The data is invalid or a newly initiated read operation has not been completed since the
latest access.
-256 File name not found
The specified filename is not found and, as a result, the command is not executed correctly.
For example, this happens when you attempt to read a file that does not exist on the disk.
This message is also displayed when you attempt to read a file on floppy disk drive, but no
floppy disk is correctly inserted in the drive.
