B) REFERENCE JUNCTION COMPENSATION USING A Pt100 PROBE
CJ MODE =PROBE
In this mode, the reference junction T2 is outside the CL521 at a location where a PttOO
probe is also installed. The thermocouple is connected to the CL521 with copper wires
and the PtIOO probe is connected to the PtIOO terminals.

C) MANUAL REFERENCE JUNCTION COMPENSATION, CJ MODE = MAN
Reference junction temperature compensation is automatically set to 0°C, using the
external reference junction. The thermoelectric potential is connected to the CL521
using copper leads.
