Changing the GPIB address
Every device on the GPIB bus must have a unique address. If you need to change
the multimeter's address, access the ADDRESS command from the command
menu (MENU keys), with the display showing:
You can enter the new address. For example, press:
1
You have now changed the address to 15. If you want to change the address back
to 22, repeat the above procedure (or use the Recall key) and specify 22 instead of
15.
Sending a remote command
To send the multimeter a remote command, combine the computer's output
statement with the GPIB select code, the device address, and finally, the
multimeter command. For example, to make the multimeter beep, send:
OUTPUT 722; "BEEP"
Notice the display's REM and LSTN annunciators are illuminated. This means the
multimeter is in the remote mode and has been addressed to listen (receive a
command).
Getting data from the multimeter
The multimeter is capable of outputting readings and responses to query
commands. As an example, have the multimeter generate a response to a query
command by sending:
OUTPUT 722;"ID?"
When you send a query from remote, the multimeter does not display the
response as it did when you executed the command from its front panel. Instead,
the multimeter sends the response to its output buffer. The output buffer is a
register that holds a query response or a single reading until it is read by the
