Description Default
[SENSe[1]] Optional root command.
:VOLTage[:DC]:RANGe <n> [, <clist>] Select DCV range; <n> = 0 to 1010 (V). 1000
:VOLTage[:DC]:RANGe:AUTO <b>
[, <clist>]
Control DCV auto range; <b> = ON or OFF. ON
:VOLTage:AC:RANGe <n> [, <clist>] Select ACV range; <n> = 0 to 757.5 (V). 750
:VOLTage:AC:RANGe:AUTO <b> [, <clist>] Control ACV auto range; <b> = ON or OFF. ON
:CURRent[:DC]:RANGe <n> [, <clist>] Select DCI range; <n> = 0 to 3 (A). 3
:CURRent[:DC]:RANGe:AUTO <b>
[, <clist>]
Control DCI auto range; <b> = ON or OFF. ON
:CURRent:AC:RANGe <n> [, <clist>] Select ACI range; <n> = 0 to 3 (A). 3
:CURRent:AC:RANGe:AUTO <b> [,
<clist>]
Control ACI auto range; <b> = ON or OFF. ON
:RESistance:RANGe <n> [, <clist>] Select Ω2 range; <n> = 0 to 120e6 (Ω). 120e6
:RESistance:RANGe:AUTO <b> [, <clist>] Control Ω2 auto range; <b> = ON or OFF. ON
:FRESistance:RANGe <n> [, <clist>] Select Ω4 range; <n> = 0 to 120e6 (Ω). 120e6
:FRESistance:RANGe:AUTO <b> [, <clist>] Control Ω4 auto range; <b> = ON or OFF. ON
Channel list parameter:
<clist> = (@SCH)
where: S = Mainframe slot number (1, 2, 3, 4 or 5)
CH = Switching module channel number (must be 2 digits)
Examples: (@101) = Slot 1, Channel 1
(@101, 203) = Slot 1, Channel 1 and Slot 2, Channel 3
(@101:110) = Slot 1, Channels 1 through 10
1. The <clist> parameter is used to configure one or more channels for a scan. Each channel in the <clist> must be set to the function
specified by the range command. If not, a conflict error (-221) will occur. For example, VOLTage:AC:RANGe 1, (@101) is only
valid if scan channel 101 is set for the ACV function.
2. [:DC] is optional for the commands to set DCV and DCI range.
