take a digital multimeter.. put it in mV Mode and place the
leads in to the thermocouple terminals .. check the mV IS
showing 0.01 for ktype (26degree celcius)... then hold the
measuring junction of the thermocouple in ur hand ..then
observe the changes.. it will vary slightly..
Note:- thermo couple leads are case sensitve(+/-) there are
different colour codes(for ktype yellow and red wires are
used cu, al yellow= positive, red= negative..)
