Remarks
This command affects both 2-wire and 4-wire resistance measurements. All
FRES and RES commands affect the equivalent settings for all resistance
measurements.
Selecting a discrete range will disable autoranging.
If the input signal is greater than can be measured on the selected range
(manual ranging), the instrument gives an overload indication: "OVLD"
from the front panel or "+9.9E+37" from the remote interface.
The instrument enables autoranging after a Factory Reset (*RST
command) or an Instrument Preset (SYSTem:PRESet command).
