13.1.8 General Programming Recommendations
Initial instrument status before changing settings
Manual operation is designed for maximum possible operating convenience. In con-
trast, the priority of remote control is the "predictability" of the instrument status. Thus,
when a command attempts to define incompatible settings, the command is ignored
and the instrument status remains unchanged, i.e. other settings are not automatically
adapted. Therefore, control programs should always define an initial instrument status
(e.g. using the *RST command) and then implement the required settings.
Command sequence
As a general rule, send commands and queries in different program messages. Other-
wise, the result of the query may vary depending on which operation is performed first
(see also Chapter 13.1.6.1, "Preventing Overlapping Execution", on page 750).
