HOW TO USE THE INTERFACE
The GPIB (IEEE-488) and USB interfaces are included as standard with this instrument.
However both interfaces cannot be used at the same time. Select either one.
6.1
Interface Selection
The interface can be selected and set only from MENU on the front panel.
1. Because the setting of the interface selection is saved in the nonvolatile memory, the setting does not
change even if the power is turned off or the interface is reset.
2. The address specific to the instrument is set in the interface. To identify each DMM on the USB inter-
face, the address of the USB interface (USB.ID) is set.
The address is displayed by turning off the power or using the address setting in MENU.
The interface setting item and the initial setting when shipping are shown below.

Response to the *IDN? Command (7451A/61A Only)
This instrument has changed its model name from “AD7451A/AD7461A” to “7451A/7461A.” Accord-
ingly, the response to the *IDN? command has also been changed. Note that an old model name response
can also be set to maintain the compatibility with the application software.
The new model name is set when the instrument is shipped.
A new or old model name response setting does not change by the initialization command or the factory
shipment initialization operation.
The new model name response to the *IDN? command is applied to software revision C00 or later.
