Resistance temperature measurements (RTDs and THERmistors) require the use
of Current Source Signal Conditioning Plug-Ons. The following table shows the
Current Source setting that must be used for the following RTDs and Thermistors:

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 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.
