Answer / vijay

T/C output is voltage . the voltage is dipance on the diff
detween the temperature of hot junction and cold function.
so the t/c junction is same temperature means it ll not
show the mv. you heat the hot jun then measur the mv inthe
output terminal and comare with standard chard before taht
check the terminal continty. then check the resistance of
the terminal if it is more the t/c is failure
