Temperature Measurement Accuracy
The temperature measurement is converted from the resistance measurement. The
Table 6 lists the temperature measurement accuracies for different wire
configurations.
Table 6 6301 Temperature Measurement Accuracy
The typical temperature noises from each wire configuration are listed at Appendix
7.5.
PFI
The PFIs(Programable Fuction Interface) are digital IO interfaces and are used for
general purpose IO, a trigger input/ output, a clock-in and clock out. In 6501, the PFI
can only be used for the external digital triggering and cannot be configured as output.
