From the instrument's interface settings, the following can be selected as the ter-
minator for response messages.

Separators
(1) Message Unit Separator
Multiple message can be written in one line by separating them with semicolons
";".
• When messages are combined in this way and if one command contains an
error, all subsequent messages up to the next terminator will be ignored.
• A query error occurs if a query command is combined with an immediately fol-
lowing semicolon and subsequent command.
(2) Header Separator
In a message consisting of both a header and data, the header is separated from
the data by a space " ".
(3) Data Separator
In a message containing multiple data items, commas are required to separate
the data items from one another.
