[SENSe:]FUNCtion:CUSTom:TCouple
[SENSe:]FUNCtion:CUSTom:TCouple <type>,[<range>,](@<ch_list>) links
channels with the custom Engineering Unit Conversion table loaded with the
DIAG:CUST:PIECE command. The table is assumed to be for a thermocouple and
the <type> parameter will specify the built-in compensation voltage table to be used
for reference junction temperature compensation. SENS:FUNC:CUST:TC allows an
EU table to be used that is custom matched to thermocouple wire characterized.
Contact a VXI Technology System Engineer for more information on Custom
Engineering Unit Conversion for specific applications.

The <range> parameter: The VT1419A has five ranges: 0.0625 V dc, 0.25 V dc,
1 V dc, 4 V dc, and 16 V dc. To select a range, simply specify the range value
(for example, 4 selects the4Vdcrange). If a value is specified larger than one of
the first four ranges, the VT1419A selects the next higher range (for example, 4.1
selects the 16 V dc range). Specifying a value larger than 16 generates an error.
Specifying 0 selects the lowest range (0.0625 V dc). Specifying AUTO selects
auto range. The default range (no range parameter specified) is auto range.
·
If using amplifier SCPs, set them first and keep their settings in mind when
specifying a range setting. For instance, if the expected signal voltage is to be
approximately 0.1 V dc and the amplifier SCP for that channel has a gain of 8,
<range> must be set no lower than1Vdcoraninput out-of-range condition will
exist.
·
The <sub_type> EEXTended applies to E type thermocouples at 800 °C and
above.
·
The *CAL? command calibrates temperature channels based on Sense Amplifier
SCP setup at the time of execution. If SCP settings are changed, those channels
are no longer calibrated. *CAL? must be executed again.

*RST Condition: all custom EU tables erased
