[SENSe:]FUNCtion:CUSTom [<range>,](@<ch_list>)

DIAG:CUST:PIECE commands. Contact a VXI Technology System Engineer for
more information on Custom Piecewise Engineering Unit Conversion for specific
applications.

The VT1422A 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 that is larger than one of the first four
ranges, the VT1422A 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.
