100 Multimeter Command Reference
The
command enables or disables the automatic input impedance mode for DC
INPut
voltage measurements.
INPut
:IMPedance:AUTO OFF|ON
:IMPedance:AUTO?
INPut:IMPedance:AUTO <
impedance mode for DC voltage measurements. When disabled (
multimeter maintains its input impedance of 10MΩ for all DC voltage ranges. This
is useful to prevent a change in input impedance, caused by changing ranges, from
affecting the measurements.
