Setup the equipment according to the following diagram for
calibrating the cold junction compensation. Note that a K type
thermocouple must be used. The programming for the controller input
and units can be any T/C type and set for F or C. Input type
programming does bot effect the cold junction calibration procedure.

Press the scroll key and the display will show
. Change the
simulated ohm's value to 300 ohms .Press scroll key for at least 5 seconds
and release scroll key. The display will blink a moment and two values
are obtained for SR1and REF1 (last step). Otherwise, if the display didn't
blink or if any value obtained for SR1 and REF1 is equal to
-199.9 or 199.9 , then the calibration fails.
