The variable name is illegal. This message is displayed when you attempt to refer to a
variable that does not exist.
-213 Init ignored
Another measurement is being executed, so the measurement start request is ignored.
141 INSUFFICIENT MEMORY
Multiple processes are executed at the same time and the memory is exhausted, which
causes the last process to be aborted. For example, if you try to simultaneously execute an
HP Instrument BASIC program, print the screen, and transfer the data array, the memory of
the system is depleted and this message may be displayed. In this case, terminate some of
the processes and then perform the next operation.
-161 Invalid block data
Block data is expected but the given block data is invalid for some reason. (Refer to
IEEE488.2,7.7.6.2.) For example, the END message is received before the length of the
block data is reached.
-101 Invalid character
Invalid characters exist in the program message string. For example, for a correct program
message, "MEAS IRIM," an ampersand (&) is inserted by mistake as "MEAS&IRIM."
-141 Invalid character data
There are invalid characters in a character data element or the received parameter is not
valid. For example, although the correct program message is "MEAS LSR," a wrong
program message, "MEAS LSD," is received.
-121 Invalid character in number
An invalid character for the data type of the syntax analysis target is received. For example,
alphabetical characters exist in a decimal value, or "9" exits in octal data.
154 INVALID DATE
You attempt to specify the date of the built-in clock with the DATE key or the SETCDATE
command, but the date is out of range and, as a result, the setting you attempt to execute
becomes invalid. The available range is: 1900 to 2099 for year, 1 to 12 for month, and 1 to
31 for day. Also, you cannot specify a date that does not actually exist. Be sure to specify
correct date 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.
112 INVALID FILE NAME
When the recall command (RECD <string>) or the re-save command (RESAVD <string>)
is executed, a string that indicates a file name is not followed by a necessary extension and,
as a result, the command is ignored. Add a required extension and then perform recall or
re-save. This message occurs, for example, when you attempt to execute the recall or
re-save command without adding an extension (".STA", ".DAT", ".TXT") to a file name. It
also occurs when you attempt to execute re-save of a graphics file without adding an
extension (".TIF").
-103 Invalid separator
