Cold-junction temperature input configuration
This input is present if the device has a thermocouple input. It is automatically used for cold-junction temperature
compensation. The parameter
yc
defines whether this input (its measurements) would also be available for
assignation to alarms and indication on front panel display in normal mode.
parameter
yc
VALUE
COMMENT
YES
The input for compensation of cold-junction thermocouple temperature is also used
for alarms and is displayed in normal mode.
no
The input is used only for compensation of cold-junction thermocouple temperature.
It is not available for alarms and is not displayed in normal mode.
default value:
no
