2Features and Functions
• Remote Interface Operation: Autoranging may be enabled or disabled for the
specified function using the following command:
SENSe:
<function>
:RANGe:AUTO {OFF>ONCE>0>ON>1}
where <
function
> = VOLTage:DC, VOLTage:AC, CURRent:DC,
CURRent:AC, RESistance, FRESistance, or CAPacitance
.
For <
function
> = FREQuency or PERiod, the range commands
affect the ac signal input voltage range.
The following command queries the autoranging feature status for the
specified <
function
>:
SENSe:
<function>
:RANGe:AUTO?
This query command returns “0” (OFF) or “1” (ON).
The following command manually sets the multimeter range for the
specified <
function
>:
SENSe:<
function
>:RANGe[:UPPER] {<
range
>>MIN>MAX>DEF}
A manual range may also be set using the CONFigure or MEASure
commands.
The following command queries the multimeter range setting for the
specified <
function
>:
SENSe:<

A Word About Ranging and Digits. The 34410A/11A/L4411A is capable of
displaying “6½ digits” for most measurements. The crossover is at a 20 percent
overload for the currently selected range. Let’s look at an example for dc
voltage with autoranging enabled. As the input voltage increases from just
below 1 volt to just above 1.2 volts, you might see the following progression of
readings on the front-panel display:
0.997,385 VDC
1.000,544 VDC
1.099,004 VDC
1.190,188 VDC
0.120,013 VDC
