[SENSe:]FUNCtion:CUSTom
[SENSe:]FUNCtion:CUSTom [<range>,](@<ch_list>) links channels with the
custom Engineering Unit Conversion table loaded with the DIAG:CUST:LINEAR
or DIAG:CUST:PIECE commands. 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 the 4 V dc range). 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 causes an error -222 “Data out of range.” 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
than 1 V dc or an input out-of-range condition will exist.
·
If an A/D reading is greater than the <table_range> specified with
DIAG:CUSTOM:PIEC, an overrange condition will occur.
·
If no custom table has been loaded for the channels specified with SENS:FUNC:CUST,
an error will be generated when an INIT command is given.
·
When Accepted: Not while INITiated
