V/A (i=3).
IGND(?){i}
The IGND command sets or queries the input shield grounding. The parameter i selects
Float (i=0) when the input ground is connected to the instrument ground with a 10 kΩ
resistor or Ground (i=1) when the input ground is connected to the instrument ground with
a 10 Ω resistor
ICPL(?){i}
The ICPL command sets and queries the input coupling. The parameter i selects AC (i=0)
or DC (i=1).
ILIN(?){i}
The ILIN command sets and queries the notch filter status. The parameter i selects to close
notch filters (i=0), open the 50Hz notch filter (i=1), open the 50Hz and 100Hz notch filter
at the same time (I=2) or open the 100Hz notch filter (i=3).
4.2.4 Sensitivity and Time Constants Commands
SENS(?){i}
The SENS command sets or queries the sensitivity. The parameter i is used to select a
different range.
