GUARD
The GUARD option is used to enable or disable guard. When disabled, the inner shell (shield) of the
triaxial connector (and cable) is connected to meter input LO. This mode is used for unguarded
voltage, current and charge measurements. When enabled, the inner shell (shield) of the triaxial
connector (and cable) is connected to guard, which follows the potential of meter input HI. This mode
is used for guarded voltage measurements.
Guard is only in effect when the instrument is in the volts function. In any other function, guard is not
used. The following menu items are used to control GUARD:
ON: Enable guard
