7.1.5 Difference between manual operation and remote control
Differences between manual operation (local control) and remote control are ex-
plained below.
(1) Single functions of the following panel keys cannot be used in the remote con-
trol mode:
• Power switch
• Cursor keys
• Encoder
•
Set
•
Cancel
•
Enter
•
Shift
•
Next
(2) While parameters to be set are selected using the encoder to start changing the
parameters in the local control mode, commands are sent to directly change the
parameters in the remote control mode.
(3) To read set values and measurement results on the screen, a query command is
sent and read the responded value.
(4) Cursor movement, screen scroll, page expansion of menu, etc. are available
only in the local control mode.
(5) Setting and reading of GPIB address are available only in the local control
mode.
(6) Setting of the GPIB interface (settings of status byte, IEEE488.2, etc.) is avail-
able only in the remote control mode.
(7) Displayed unit on the screen may differ from the response unit for remote con-
trol. In the remote control mode, a value is always returned in a predetermined
remote control unit.
