In the settings mode AC with current feed, an open-circuit current-fed voltage of about 30 V is
present at the BNC sockets, which can cause damage to other (non-current-fed) sensor types. For that
reason, this mode should only be set for appropriate sensors. It is assured that no current feed is
active when the device is started. This state remains in effect until the measurement is first prepared,
no matter what is set in the user's interface.

When a channel is not active, there will be no current-fed voltage in the settings mode AC with
current feed as of firmware version 2.7R3.
