Next, run a series of measurements and record the results.... First measure the temperature of vigorously boiling water, then immerse the t/c junction into a large glass containing crushed water-ice, then back to the boiling water.
Compare the recorded results and note the variation. Head over to your Elevation Tables and note the corrective factor you need to use for your current Elevation then see how far the results differ from the empirical data. I doubt you will find a significant variation and I feel pretty sure that repeatability will also be very tight. For our purposes, this is a very reliable and accurate method to use with variability held to quite tight tolerances which Im sure you will confirm should you decide to undertake the simple experiment outlined above.
Sure, if youre going to use the same t/c and DMM for measurements that range from one extreme of the K-Type t/cs capability to the other then there are calibration steps that need to be taken to ensure the results are meaningful. This is absolutely unnecessary within the range of 0-100°C though. Hope this helps a bit mate
