Description
This command queries the 34410A/34411A multimeter to determine
whether the front or rear input terminals are selected (via the front/rear
switch on the front panel).
The front/rear switch should not be toggled with active
signals on the terminals. This switch is not intended to be
used in this way, and may be damaged by high voltages or
currents, possibly compromising the instrument's safety
features.
