11.3 Controlling the Instrument with Commands and Acquiring Data

For more information about communications commands and query notation (from the com-
munications message reference), see the Communications Command Instruction Manual
on the included application disc. When creating programs, the communications monitor
function can be used to display commands and their associated responses on the Mea-
surement screen.
IEEE 488.2-1987 standard (essential) commands can be used with the GP-IB interface.

When the output queue becomes full, a query error will be issued, and the output queue will
be cleared. Therefore, clearing the output queue and query error output from the dead-
locked condition
*3
as defined in IEEE 488.2 is not supported.
When the interface setting is set to the printer, proper command operation is not guaran-
teed. Do not send commands.

Instrumentation

Common Commands
*3 The situation in which the input buffer and the output queue become full, so that
processing cannot continue.
During remote control operation,
[RMT]
appears on the Measurement screen, and all
except the MENU key are disabled.
Pressing the [LOCAL] disables remote control and re-enables the operating keys.
In the local lockout state (GP-IB command LLO: Local Lock Out) selecting
[LOCAL]
on the
screen has no effect. In this state, send the
GTL
command, or turn the instrument off and
back on to re-establish local control.
If the Setting screen was displayed when remote control was enabled, the instrument
returns to the Measurement screen automatically.
