Interface check

To perform the GPIB interface check, the power supply must be connected to the
controller via the GPIB; therefore, you need a GPIB interface card + software
GPIB drivers + a programming language.
The various parts of the following interface check must be executed sequentially.
Your power supply goes into the remote state when the first command is sent via
the GPIB. However, the results of programmed commands can still be monitored
on the display, e.g., the readback voltage and current. Also the text REM will be
displayed in the remote state.
The interface check consists of the following parts:
Check the GPIB address setting under the AUX menu.
