Removal of the CJ sensor from the input
board terminal block to allow use of
channel 1 to measure resistive inputs
(Input type = RTD or Ohm).
It is recommended that when mixed inputs
are being used, thermocouples are wired
to the lowest channel numbers. If channel
1 is set to RTD or Ohm, then the CJ
sensor must be disconnected, as shown
above, and any other channel set to
Thermocouple must use an External Cold
Junction.
1. Prise cover off
2. Release terminals
11 and 12
3. Remove CJ sensor
