J. Sourcing Resistance Into a RTD Transmitter
1. As described previously in section F the PCL1000 can source resistance
in a RTD Transmitter or measuring device. In many cases the unit under
test will require a 3 or 4 wire connection to achieve best accuracy. Refer
to Figure 10 for connection information.
