Introduction
Configuration Errors
Command module error messages associated with system installation and
configuration are listed in Table 5-3. These errors are displayed if a terminal or a
printer is connected to the R S-232 port of the command module.
If a printer or terminal is not used, error messages can be read from the system
instrument error queue, using SYST:E R R ?. E xecuting the SYST:E R R ?
command reads the oldest error message from the instrument’s error queue and
erases that error from the error queue. An example program follows.
Example: Reading the Error Queue
This program reads all errors (one error at a time, oldest to newest) from the
system instrument’s (command module) error queue. After reading each error,
that error is automatically erased from the queue. When the error queue is
empty, this program returns: + 0,"No error".

Operating System Errors
(No error num bers)
System Errors: Generally halts instrum ent operation. Read errors from a term inal
connected to the RS-232 port of the com m and m odule.
