SCPI Command Reference
Select auto range
:AUTO <b>
[:SENSe[1]]:CURRent[:DC]:RANGe:AUTO <b>
Control auto ranging for amps
[:SENSe[1]]:VOLTage[:DC]:RANGe:AUTO <b>
Control auto ranging for volts
[:SENSe[1]]:RESistance:RANGe:AUTO <b>
Control auto ranging for ohms
Parameters
<b> =
0 or OFF
Disable auto range
1 or ON
Enable auto range
Query
:AUTO?
Query state of auto range
Description
This command is used to control auto ranging. With auto ranging enabled,
the instrument automatically goes to the most sensitive range to perform the
measurement.
When this command is used to disable auto range, the instrument remains at
the automatically selected range. When a range is manually selected, auto
range is disabled. See the previous command.
:LLIMit <n>
[:SENSe[1]]:CURRent[:DC]:RANGe:AUTO:LLIMit <n>
Set auto ranging lower limit for amps
[:SENSe[1]]:VOLTage[:DC]:RANGe:AUTO:LLIMit <n>
Set auto ranging lower limit for volts
[:SENSe[1]]:RESistance:RANGe:AUTO:LLIMit <n>
Set auto ranging lower limit for ohms
Parameters
<n> =
-105e-3 to 105e-3
Amps lower limit
-21 to 21
Volts lower limit
0 to 2.1e13
Ohms lower limit with PreAmp
0 to 2.1e7
Ohms lower limit without PreAmp
Query
:LLIMit?
Query auto range lower limit
Description
Auto range lower limits are intended primarily for SYST:RCM MULT sup-
port. See :
SYSTem subsystem
. The lower limit for all three functions is pro-
grammable and must be less than or equal to the upper limit. If the lower
limit is equal to the upper limit, auto ranging is effectively disabled. See
below. When autoranging is disabled, you can manually program the unit
for any range below the lower limit.
:ULIMit <n>
[:SENSe[1]]:CURRent[:DC]:RANGe:AUTO:ULIMit?
Query auto ranging upper limit for amps
[:SENSe[1]]:VOLTage[:DC]:RANGe:AUTO:ULIMit?
Query auto ranging upper limit for volts
[:SENSe[1]]:RESistance:RANGe:AUTO:ULIMit <n>
Set auto ranging upper limit for ohms
Parameters
<n> =
0 to 2.1e13
Ohms upper limit with PreAmp
0 to 2.1e7
Ohms upper limit without PreAmp
Parameters
:ULIMit?
Query auto range upper limit
Description
Auto range upper limits are intended primarily for SYST:RCM MULT sup-
port. See :
SYSTem subsystem
. For voltage and current, the upper limit is
controlled by the compliance range and, therefore, is available only as a
query. When autoranging is disabled, you can manually program the unit for
any range above the upper limit (ohms only).
