why temperature transmitter is showing ambienttemp.but 21.5ma.
alarm AO showing at the display &how to sloves this problem.

Answer Posted / carl_ellis

A short circuit (both thermocouple wires touching each
other) in the thermocouple extension wire leads will create
an ambient or near-ambient temperature reading, but I am
unaware of any temp transmitter that can detect that problem
and go to fault mode at 21.5mA.
