a. FUNCtion <name> [, <clist>]
Note that the <name> parameters in the table are enclosed in single quotes
(‘ ’). However, double quotes (“ ”) can instead be used. For example:
FUNC ‘VOLT:AC’ = FUNC “VOLT:AC”
Scan configuration — When using the <clist> command to configure a scan
channel, the scan channel must first be set to the appropriate function before
sending other commands to configure it. For example, to set scan channel 101
to use offset-compensated ohms, the following command sequence would be
sent:
FUNC 'FRES', (@101) ' Set scan channel 101 to
Ω4 function.
FRES:OCOM ON, (@101) ' Enable offset-compensated
ohms for scan channel 101.
If scan channel 101 was not first set for the Ω4 function, the following errors
will occur for the following operations:
• Error -221 (Settings conflict) will occur when trying to enable offset-
compensated ohms for that channel.
• Error +700 (Invalid function in scanlist) will occur when trying to query
the state of offset-compensated ohms for that channel:
FRES:OCOM ON? (@101)
Details on scanning are provided in Section 7.
b. FRESistance:OCOMpensated <b> [, <clist>]
The instrument does not have to be on the Ω4 function to enable offset-
compensated ohms. When Ω4 is selected, offset-compensated ohms will be
enabled.
When using the <clist> parameter to configure a scan channel for offset-
compensated ohms, that channel must already be set for Ω4. If set for another
function, a settings conflict (-221) will occur.
TEMPerature:TCouple:RJUNction:RSELect <name> [, <clist>]
c. To use the EXTERnal reference junction, the scan channel (101, 201, 301,
401, or 501) to be used for the measurement must already be configured to use
a thermistor or 4-wire RTD transducer. Otherwise, a settings conflict error
(-221) will occur. The TEMPerature:TRANsducer command is used to select
the transducer.
NOTE The following command can instead be used to select the reference
junction:
TEMPerature:RJUNction:RSELect <name> [, <clist>]
