Resistor Connections
Table 5 shows which resistors are associated with each group of channels.
SCXI-1102/B/C Module
You can replace the 10
Ω
ground-referencing resistor networks
(factory-default configuration) in the BNC/TC-2095 with the 10 M
Ω
resistor networks supplied in the kit. The 10 M
Ω
resistor networks allow
the signal to be ground-referenced or floating. Channels with open
thermocouples saturate at all sample rates.
Use long-nose pliers to remove or replace the resistor networks in the
sockets. Be careful not to damage the network package. Make sure pin 1
of each network is in the correct socket. Refer to Figures 6 and 7 as needed.
