Explaination of thermocouple chart ?

  1. Dec 11, 2012 #1
    The Y axis represents the temperature of the measurement junction in a thermo couple chart and what does the X axis represents ?

    http://www.pyromation.com/downloads/data/emfk_c.pdf. This is a chart for K type thermocouple.

    Does it represent the temperature of the refernce junction , if yes then why only till 10 deg C.

    Both axes are temperature: The rows are steps of 10 and the columns are steps of 1.

    If you want to know the voltage at -255°C, you have to look in row "-250°C" and column "5" and get -6.425mV.
